« on: February 26, 2017, 03:36:07 AM »
I'm trying to make sure I understand all the items I need to do an LS3 swap in my 78 403 TA before I actually go through with it.  I plan to do the swap ASAP.

I like the Holley adapter plates and cross member.  I feel they are well made and well thought out.  The set centers the engine/trans within the chassis at about a 3 degree angle (I believe).  They have sales every so often.  The motor mounts required with their engine mounts are standard typical Chevy style clam shell used in the 70's and 80's.

I bought an '11 Corvette motor complete and it's accessory drive.  Everything fit's well.  The AC bracket/compressor does not fit, but it's not compatible anyway with VA.  I thought I read that Pace Performance sells the Corvette brackets, water pump, balancer and alternator in a package for a deal.  It's been a while since I looked into it. 

I used Aeroquip fuel lines and fittings.  I had 1 leak at a 90 at the fuel rail (Summit fitting).  All worked well, but I am switching to conifer (copper nickel) now.  I just like the neater/cleaner look.  If you do go with the flexible line, PTFE lined is the recommended to avoid seeping of fuel. 

For your temp guage to work, you'll need to get an adapter and thread the original sender from your current motor onto the passenger side of the head.  Oil pressure can be read at the top rear of the valley cover if it isn't used by your harness (I'm not familiar with the E-Rod harness).  If the E Rod harness uses the sensor mounted there, you can tap the cover near the filter to thread the sensor there. 

Driveshaft will have to be custom made after measuring.

You may need the Corvette fuel filter which creates a returnless fuel system. As for fuel line, I installed plastic ones like a new car has. I bought the tubing from Napa along with the press in fittings. The only place for leaks would be the filter as this is one piece of tubing.

Radiator and fan I pulled from a 4th gen firebird. It fits right in like it belongs there. The AC condenser from the same car fits really nice as well.

Oil pan I used was a stock 4th gen part as well. Fits great in the frame.

I guess I need to add a few more things to my list:


Fuel lines (re-circulating or returnless)
Fuel tank vent line from the tank to the evaporative emissions canister
Pure line from the canister to the engine purge solenoid
Air induction system that incorporates the mass airflow sensor
Exhaust system behind the catalytic converters

Question...

Does the "x" in "LSX" mean a variable? So that is can be a generic reference to any LS engine, like LS3, LS7?  Or is there an engine that is specifically an LSX?

The Ls3 stock is a returnless system.  No need to run a return a line.  Either use a modern (5th gen Camaro) style pump assembly or you can run a Corvette regulator. 

I plumbed my vapor line into a Finch canister.  Can't help on this one.  If you have the stock charcoal canister, you can run it to that.

Air Induction: I used Spectre swap cold air induction kit.  You can either buy a mount and have it welded to their tune or buy one from them with it already done. 

You can plump it all to your existing exhaust and see how it sounds and performs from there.

The oil pan you have listed is just a Hummer pan I believe.  I read that a Corvette pan wouldn't fit and considered that pan.  I decided to see where my Corvette pan would interfere by dropping the motor in.  I was surprised at how well it fit.  Like it was made for the car.  The Hummer pan has a greater slope to it if I remember right.  It is also deeper and would most certainly hang below the cross member.  I don't see how that pan would/could fit on our cars....at least using Holley mounts.  I only have crappy pics of the clearance.

The shakers are a little different for some of the different years.

Just a couple of hours ago I showed your shaker adapter to the shop that will be doing my swap.  They really like your kit.  They'll be ordering it on my behalf in the next few weeks when my car goes in for work.

The GM part number you listed for the oil pan is the muscle car pan as GM refers to it. That pan will not work in the 2nd gen f-body with out hanging below the cross member.

I used the BRP LS swap kit in 2 different cars now. My 73 Formula and my buddies 73 Camaro. In my car I used the Headdmen headers made to go with the BRP kit and a Griffen rad w/fans. I also used Dirty Dingo f-body brackets with truck spacing to get everything low in the engine bay. On my buddies 73 Camaro we used the cheap $200 stainless steel swap headers and a set of Dirty Dingo brackets that placed the acc. in close to the stock Pontiac pos.

I have a build thread here on the forum http://transamcountry.com/community/index.php?topic=73408.280

I will head down tomorrow or Monday to spotweld your airbox together - I usually store them in pieces as they are pretty bulky when built.

I have a build thread here on the forum http://transamcountry.com/community/index.php?topic=73408.280

I'll be getting a lot of parts from BRP hot rods:
http://www.brphotrods.com/products/2nd%20gen%20F%20products/index.html

206-0002-60         LS and 4L60E to 4L70EMount and Crossmember Kit $489
000-6200-00         F-body Oil Pan $399
613-9005-0A        70-81 Camaro LS Radiator (Auto trans) with fans           $925.00
206-6682-04       78-81 Camaro/ 79-81 Firebird Tank kit - 255 LPH pump    $569.00


I did not order yet.  But shipping seemed pretty high (I think around $150) but after putting it in my basket it said to call the place, so I'm guessing shipping will be less if you buy multiple items at the same time....

But for the fuel tank, I most likely will get this one, that is less expensive plus free shipping:
Spectra Premium GM203FI Classic Fuel Injection Tank $416

Would you suggest me to get the Dirty Dingo brakes too?  If so, which ones?  And does that mean I should not get this kit I listed in my last post:
206-0002-60         LS and 4L60E to 4L70EMount and Crossmember Kit $489
This kit can be broken down if I just wanted to get some of the parts.  Which part would I still need to order? 
Or is this enter kit just as good as the Dirty Ding?

I am a very dumb mechanic, so sorry for all these silly questions  :shock:

I wouldn't wish the hummer pan on my worst enemy. It hangs really really low. I had one on my car at first and quickly changed to the Holley pan. The Holly pan is about even or just above the crossmember height. I bought the E-Rod LS3 HotCam 480hp setup and it came with the hummer pan.  If i had to do it all over again on another 2nd gen, (and I am...), I would get the Holley pan. I think I have more pics of the pan swap in my signature "Build" thread.

The EROD is CA emissions compliant; I do not remember an EROD version that was 480 hp.

Is this the same pan you got?

pan that came with it wouldn't work in the car. so gm sent us the muscle car pan...hummer pan. we lived with it for a very short time before going to the holley pan. the engine is a beast.  :twisted:

I was looking at a non-EROD motor for my 71 Lemans; though 430 horse would be enough.  I actually wish they made an aluminum block version of the their 5.3 in a crate motor.

Sorry I just seen this.

2 thinks for you don't get the pan from BRP, I have a list of part numbers I will dig up for you for the are that you need for the oil pan. The 2 cheapest places I have seen to get the oil pan is GMpartdirect.com, but I would get the oil pan from Autozone as it is cheaper there and get the rest of the part you need from GM.

12558251   SCREEN         $31.95
12551577   TUBE             $8.02
12551581   INDICATOR    $12.39
12558253   DEFLECTOR    $16.88
12628771   PAN               $188.65   

You can do as you please on the rad, but my Griffen only cost $645 from Summit Racing part # GRI-CU-00010-LS, now this rad is for a manual trans, personally I prefer to run an external cooler.

As for the Dirty Dingo brackets, there is a preference on how you want the acc. to set in the engine bay, I liked mine down low. If you go look at my build   http://transamcountry.com/community/index.php?topic=73408.280 I have a ton of pics posted. I'm not going to say use these brackets, but I will say take a look at what is all out there before you make up your mind.

I have found most of the bracket kits work with the BRP engine mount kit.

GM also has a new LT1 - E-Rod

i think this might be the direction I go

they also have their new 8L90-E _8 speed transmission with a 4.56 1st gear

having Dick Miller build your stock 185 hp 403 into a 455+hp engine will cost you $11,000 easy...

then how streetable will that be?  ...and once you open up your numbers matching engine to make the refinements needed to handle a 455 HP beast.....it will never be factory stock block again ... and it will never pass California Smog with it's 455HP heads and cam

but

dropping in a LT1-E-Rod and it's 8L90-E _8 speed transmission you have a streetable and emissions compliant car that you can drive daily and  gives you the option of keeping your original numbers matching engine and transmission with the car if you want to sell it later ..

wow.  11 grand but you get a state of the art direct-injection, variable valve timing, etc.


having Dick Miller build your stock 185 hp 403 into a 455+hp engine will cost you $11,000 easy...

then how streetable will that be?  ...and once you open up your numbers matching engine to make the refinements needed to handle a 455 HP beast.....it will never be factory stock block again ... and it will never pass California Smog with it's 455HP heads and cam

But as some will say, that is not a Pontiac engine.

I think you are confusing me with Jonathan's EFI/403 um, opinion.

I am all for modern transplants, especially after doing one.

Sorry I just seen this.

2 thinks for you don't get the pan from BRP, I have a list of part numbers I will dig up for you for the are that you need for the oil pan. The 2 cheapest places I have seen to get the oil pan is GMpartdirect.com, but I would get the oil pan from Autozone as it is cheaper there and get the rest of the part you need from GM.

12558251   SCREEN         $31.95
12551577   TUBE             $8.02
12551581   INDICATOR    $12.39
12558253   DEFLECTOR    $16.88
12628771   PAN               $188.65   

You can do as you please on the rad, but my Griffen only cost $645 from Summit Racing part # GRI-CU-00010-LS, now this rad is for a manual trans, personally I prefer to run an external cooler.

As for the Dirty Dingo brackets, there is a preference on how you want the acc. to set in the engine bay, I liked mine down low. If you go look at my build   http://transamcountry.com/community/index.php?topic=73408.280 I have a ton of pics posted. I'm not going to say use these brackets, but I will say take a look at what is all out there before you make up your mind.

I have found most of the bracket kits work with the BRP engine mount kit.

Chevrolet Performance Engine Oil Pans 12628771

Is this the oil pan?
It showed up in Autozone when I did a search for"12628771" as:
Spectra Premium Oil Pan
http://www.autozone.com/external-engine/oil-pan/spectra-premium-oil-pan/544433_0_0?&searchText=12628771

Edit:
Forgot to ask: the extra items you listed above the pan, would I be able to take those items off the pan that is included with the LS3 engine and use it on the pan you suggested?

Edit2:
I tried to see if Autozone had the pan in stock and tried to order...no longer available...too bad because is was about $140 after using their coupon...

I'm not sure you will be able to use the other items off of the LS3, because all these items have to work together with the oil pan.

I would go into a local zone and try to order a pan for an 2000 Camaro with a 5.7 v8 instead of going by the GM part number. I have a buddy that just picked one of the spectra part about a month ago.

I will head down tomorrow or Monday to spotweld your airbox together - I usually store them in pieces as they are pretty bulky when built.

I missed your delivery yesterday, so I picked it up from the post office.  Thanks!

...
I bought an '11 Corvette motor complete and it's accessory drive.  Everything fit's well.  The AC bracket/compressor does not fit, but it's not compatible anyway with VA.  I thought I read that Pace Performance sells the Corvette brackets, water pump, balancer and alternator in a package for a deal.  It's been a while since I looked into it. 
...

Is this the one you got?
https://www.summitracing.com/parts/nal-19155067

It's a lot less expensive than the BRP one at MuscleRods.  BRP use the vintage air unit, and the GM one uses their own GM.  So either way I would not get the compressor separately like I first thought I would be doing since I can get either the BRP or the GM as a kit with the accessory drive. 

So if I got the GM kit, would everything fit good?  Everything thing else for the AC system I would use OE stock replacement parts.

Thanks.  Today I was at the shop that will be installing it and the engine and everything else.  I'll be ordering the engine/trans today.
