424 Oldsmobile Stroker 403
« on: August 04, 2018, 06:02:03 AM »

Just picked up the 424 cubic inch stroked roller Oldsmobile 403 from the machine shop.  Took 20 months to get all the parts and machine this motor.  Did it twice. 

Not many out there like this one. 
Bored and Honed to .024 using torque plates
Decked to .008
Align honed and clearanced
Stroked 1967 olds 330 forged crank stroked to 3.510
Custom forged pistons by Racetec. 
Metric ring pack 1.5 mm 1.5mm 3.0mm
Scat small block chevy small journal rods 6inch
Custom lunati roller cam
Roller lifters
Halo girdle from J&S machine
Holley dominator intake cut and decked.

1970 small block 350 Heads bulit and ported by Champion Racing in Florida. 

Special thanks to Mark Remmel (CutlassEfii) on Realoldspower for all the parts.  Thanks to Precision Engines in Austin, Tx for all the time and efforts. 

There is a bunch of machine work and time test fiitting cranks and such.  There is thousands in machine work.  I stated two years back this would be a max effort 403 which is now a 424 cubic inch small block.

I hope your Holley intake works better than the Torker I had on my 425 decades ago - quite the pig low end.

The Holley small block dominator is the only single plane intake for the Oldsmobile that was made.  Long out of production. Torker was not made for small blocks. I have a paper thin performer that 1lb of aluminum was ported out that I have on another car.    I am running a 298mm torque converter with fuel injection and the combo is well thought out.  Will all specs later and should not be a pig.

I hope so - my 425 had ported heads, headers, M21, 3.90 and a Mondello cam.  Eddy later made a T2 for the BBO IIRC that supposedly ran much better.

The dominator runners are narrow which slows the port velocity.  The cam is 227/232 @.050 with .561 intake and .551 exhaut on 112 center.

Okay, I see you have a 3.510 Stroke Crankshaft to yield 424 ci.  Does anyone know if anyone has taken a 4" crankshaft and put it in a .030 over 403, to yield 482 cubes?  This would be 4.381 Bore X 4" Stroke.  Years back they used to take Olds 350 Diesel Blocks and then take a 3.975" Crankshaft from a late 60's (maybe 1967) Olds 400 or 425 big blocks, and then cross-mill the 3.975" crankshaft to make a 4" crankshaft for a Small Block Olds.  For an Olds 350, you could get around 440ci.  Question is, can you fit a 4" crankshaft in a 403 to result in a 482ci small block, without anyone pointing out that the 403 has windowed webs? 

also, on this 424ci, will you have dyno numbers available in the future?  What is the compression?

Just when I thought my 421 stroker was risky from my 403 :)  Mine has tons of torque and power.  Excited to see what you end up with from this build.

This is an awesome build for sure!

I've always wanted to see someone utilize the Olds 307 computer controlled distributor and GM TBI on one this type of build.

Wicked engine. I wish I'd done something similar with mine, it was certainly the plan but there was no engine guy or parts suppliers who took much interest so I ended up with something that cost a fortune for mediocre outcome. Disappointing all round, hard to argue with the anti 403 crowd. But this one sticks it to them.

Funny someone asked about the 4” stroke crankshaft.  I have one new billet.  I won’t put it in a 403.  It will go into an Olds Diesel block.  Yes, you can take a 425 olds crank and cut down the counterweights and fit it into the Olds Diesel.  I considered it.  Though its not as nice as a brand new billet and nearly the same cost.  I already got screwed on my stroked  330 used crank which cost me $750+ to get a virgin one stroked and narrowed for sbc rods and then another align hone on the block.  Not doing that again as Olds stuff is a fortune. 

To answer the above post on the 403 - the deck is .008.  The heads were cut to 63cc’s.  I am using cometic MLS head gaskets.  Compression calculations are 9:71.  I know approximately what the motor will do as modeled it after this one.  https://m.youtube.com/watch?v=3gwx36SQ3vs

That stroker 403 was done in Dallas Tx.  Just up from me.  Granted this, one has BB heads, but I put big valves in my heads and ported them to paper thin.  The choke point will be the intake/exhaust as That 424 is going into my Dad’s 10th Anniversary Trans Am and it will look all stock.  I actually need to tame this motor down.  The trans is rock solid and so is the rear. The details are in the restorations section of this forum

It was the last 403 we will build as it was a lot of time and money.  Everything was custom and was a lot more money than initially expected.  The machine work was done twice on the short block and heads were done twice too.  Lesson learned - used parts were junk and had to find replacements. 

No more 403’s will be built as I said last year.  Blocks are extremely hard to find and so are parts. Just sold a set of 350 #6 heads to the shop that did my motor.  Still have a set of forged TRW old stock new inbox pistons .030 and a set of KB’s that I will sell as well.  Probably have a set of 4’s, 5’s amd 6’s that are good heads too.  Just have to check inventory.  Have an old set of 4A’s I have pocked ported i the 80’s that need to go too.  Plus a new custom erson cam setup for a mild 350HP build that has to go too.

thanks. Mike

This is the 4” small block billet crank - No you WILL NOT find one anywhere online.  Its a game changer as now as any small block Olds can push 425+ cubes and 500HP.  Its not a joke.  I have this crank.  Just find an Olds 350 and make HP.  403 will be 482 cu in.  Not recommended. 

Go on classicOldsmobile.com and talk to cutlassefi.  aka Mark Remmel.  Mark is very helpful and patient.  All the parts and head work Mark has done for me.  Not cheap...

Marks crank would make killer power in a 403! Would you not recommend it even with a girdled bottom end?

nice build, sounds expensive.

I am finally getting back to working on my car and plan on building/having the motor built this winter. J&S are somewhat local to me so debating having him build it. is it possible to get 400-500 hp out of it at a reasonable cost?

400 hp is easy.  KB pistons,  BB heads, RPM intake, and good cam.  This would not be terrible on the budget.  Define reasonable? 

Yes, the stroker 403 was expensive as nothing was off the sheld - well maybe the scat chevy rods since chevy parts are cheaper by a 2x to 3x factor. 

It would have been about $1500 less if the first crank would have worked out and not doing it twice.  Mind you, its not just the crank...it’s another align hone for the replacement crank plus balance job too.  Everything on this build was custom (crank, pistons, rings, and roller cam) which makes it quite a bit more money.

Let's see, I think you mentioned in this thread that you have 1970 small block heads, so I assume that these are #6 Heads.  You mentioned that they have been milled down to 63cc and that the compression of your 403 (now 424ci) will be 9.7:1.  Have you had these heads flowed, and if so, what is the CFM at .500 lift and at .600 lift for the intake and exhaust?  Also, what size intake and exhaust valves are in these Heads?  2.00?  2.07?

Checking pushrods.  Stock is about .050 took long.  Ordered a set of Manley 8.200.  Everything is custom.  Measured and thought out.  Even had a set of 1/4 valve cover spacers made.  Stock look.

8k is about where you will end up.  Just depends on what you do on your own.  I have a set of KB’s new in box .039.

An Olds 425 V8 has 3.000 inch diameter main journals. Larger than a 403.
The Thrust main checks are wider than a 403.
A 350 D Olds V8 has the Large 3.000 inch main journals.

So you can not physically drop a 425 V8 crank into a 403 block.

I have a 1965 Olds 425 Super Rocket V8 in my 1963 Pontiac Grand Prix.
Fit it with some minor work.
Runs like a bat out of hell on fire.

         424ci SBO is looking good.  Keep sending the pictures as you progress.  So, you have 424 cubic inches, 9.7:1 compression, 2.125" intake valves in 64cc #6 heads, and a cam that specs out with a Duration of 227/232 @.050 with Lift of .561 intake and .551 exhaust on 112 center.  Forget, is this a hydraulic roller?  I think you mentioned that the heads flow 244 @ .500 lift and 254 @ .600 lift.  So, if you do get .561 lift out of you cam, you should be right around a flow of 250 cfm on the intake side. 
         I think you mentioned that this is going in a 10th Anniversary TA.  Will this engine have headers and perhaps a Pypes 2 1/2" Dual Exhaust?  What Carburetor do you plan to use and cfm?  Any plans on timing?  Just curious what Horsepower and Torque numbers you hope to get with this combination. 
         Also, is this 424ci SBO being backed by a TH350?  What rear end ratio will the TA be running?

Hydraulic lunati roller.  200r4 billet transmission 298mm lock up converter  built by Dave Husek
3:23 rear end. 2.5 pypes with Thornton W/Z manifolds.  I have a set of super comp headers too, but going for a stock look and headers are there for later.  Need to keep it a bit tame for a while given it’s my Dads car.  The motor will easily put down 450hp and being that it’s stroked it will rev fast. 


The fuel system is a fuel injection system in tank with Fitech. 
Ignition is one of Rocky Rotella’s Sun Tuned HEI.  He did it for me about 15yrs ago. 
10th Anniversary Trans Am which is posted in the projects and restorations section
A lot has gone into this restoration.  No expense spared.  Doing it right

Is that a Pontaic 455 ? No, olds 403 with a stroker crank, chevy rods, and custom pistons.  Sure it will start a conversation.  Considering I will be using a Pontiac 400 air cleaner housing.  This will get everyone confused. 

Honestly,  it was either Ford Blue or Pontiac blue from KBS.  So, went Pontiac blue.  Close enough to the genre and timeframe these cars were built.  Never said it was going to be 100 point restoration. 
Original 4WD brakes are gone now and so is the brake system.  All hydroboost with 1LE upfront and S10 brakes in the rear.  Sometimes, captain’s call.

Dude, you should reconsider that Paint choice!  Puke Blue?  LOL   :shock:  You should go with 1970-72 Oldsmobile Blue Metallic for the Block and then Pontiac Light Blue Metallic for the Valve Covers, Water Pump, and other accessories.  Just joking, you can paint it any color you want! 

So, are you going to dyno-test this bad boy before it goes in the car?  Or put it on a Chassis Dyno when everything is hooked up and ready to go?

The motor took too long already and about 6 months behind given the machine shop delays/crank replacement.  The plan was to dyno the motor as would really like to know myself.  Though not important to the overall plan since its not going to be raced. 

The paint is what it is now and KBS piant shoots like an oil based paint then has a long cure time.  The valve covers were shot in GM corporate blue out off a rattle can.  The KBS paint will be on the block / intake for  life unless cooked / bead blasted off now. Not overly concerned about being the pontiac blue and it was either this or rattle can.  Rattle can lasts about a year at most and then burns/flakes off from my experience.  I suppose to be Era correct it should have been a gold painted Olds motor since  major parts used are 1967 or 1970 expect for the block.

What can you share about that FiTech Unit sitting on top of the 424ci SBO motor?  Since I have a Holley 750cfm Vacuum Secondary Carb on my 403,  I am curious how the FiTech works and how programmable/flexible it is to adjustments to make for a better running motor.  Are you able to dial in an AFR (Air-Fuel Ratio) around 14 or wherever a 403 runs best and produces the best vacuum at idle?  Can you elaborate on the pros and cons of this FiTech and what cfm it flows?  And, all the components (linkage, etc.,...) needed to make it work, going back to and from the Fuel Tank?

I posted the FiTech a couple of years back when I ran one on another 403.  It’s basically a electric carburetor.  Starts up and idles no warm up..ect.  It has an O2 sensor that goes into the exhaust.  It has a self learn I pretty much left it alone since.  I think for all those pros/cons details look fitechs site or join their FB page.  Its not a complete EFI system with infinite options like an AEM ECU/Fast system.  By the time you get into something like AEM you are well beyond DIY.  FiTech are simple throttle body injection and DIY.  These a good option if you just want to bolt on and go.  Same can be likely done with a well tuned carb using a wide band sensor and enough dyno time. 

The fuel system is an efi tank with a walbro 255 fuel pump in the tank.  AN6 Fragola PTFE line from rear of tank to 3/8 Alum fuel line at the subframe and AN6 for the return back to tank.  At the Fitech there is a prefilter from Earls and that is AN6 with alum line to pushlock Fragola to AN6.  The biggest expense is the tank and all the lines and fittings.  Hard part was all the tube to AN adapters and making all the lines. 

The throttle bracket is a holley for 700r4 as I have a 200r4.  The linkage for it is all based on a holley so dont see any concerns.  Now, on a stock intake if you find my old post the TV/Detent hit the egr boss on the edelbrock performaner.  Ground the inake a bit. 

Right now I dont know what this 403 will do with this setup/Cam and how the FiTech will respond.
