Jonathan,

Motor looks great, I like that you’re staying with Pontiac paint color and old style intake. Having good lighting in your garage is invaluable, I would have been real nervous working over your car with that beautiful paint.

Jonathan,

Thanks!  Yea, I'm pretty excited to do up this engine in an original 70's appearance.  A lot of people spend a lot on coil covers and other "old-school" dress up parts but I won't be going that far.  Aside from the carburetor, I'll mostly be doing stock LS stuff but painted to look like a 70's engine.

Man, I wish nice paint was the case haha!  I know some angles and distance make it look pretty but the car has rust in various areas and it would need a repaint to be nice.  It needs much attention on the body actually.  I won't be going that far in the near future but we'll see how life plays out.  Right now my main focus is mechanics and getting it functioning again.

Got some time in the garage today.  Decided to wipe down my super grimy 5.3 valve covers and throw them on the LS1 to give more of a factory '79 W72 400 look to the engine.  Doing this job with brake cleaner and rags wass not fun but I got it done.  Results aren't the best, but it's something.  After I finished cleaning the covers, I wiped down the coils/brackets and put them on.  Followed up by spark plugs, wires and the oil filter to keep the engine sealed up.  Last night I cleaned/painted the steam tube from my 5.3 and put it on the LS1 as well.

Looking great!  What did you paint it with?  Looks about the same colour as I used on my oil pan, hoping he paints the motor to match :shock:

Thanks Kerry!

Nothing exotic here haha.  Just some Dupli Color engine paint in Pontiac Blue.

It's funny how just a color makes you think it's a Pontiac.  The throttle body will be the icing on the cake. Looks great!

Engine looks good. How does it compare in weight to a Pontiac 400? I am assuming several hundred pounds less, but have no idea.

Thanks for the interest guys.

roadking77, my idea on this car has been to incorporate many of my favorite aspects of Firebirds in general.  I actually have an LS1 being finished up by someone right now and it will be mated to my original 4spd transmission.  The drivetrain should shave a lot of weight.  The wheels are 4 front 16x8 0 offset '84-'87 WS6 wheels I had refinished along with BFG Comp-2 255/50-16 tires.  I also have 3rd generation '87 GTA seats but I'm thinking I'm going to sell those and go back to original 2nd gen seats.  The 3rd gen works, they're super nice and I got them to fit the car but rears are not great for swapping and I want to have an easy/matching interior in the end.

Here was an update last week on my engine.  I should have it back within the next few weeks here.

I have a set of those wheels, and was wondering what lug nuts you ended up using.Thanks.

Got my carburetor today. 

I never thought this would happen but this was a crazy shopping experience that took about a week to figure out. In the beginning of shopping carburetors, I was set on getting a 650 for my LS1 and after searching around, I found the prices for standard Holley 650's are pretty expensive while being on back order.  Other brands such as Brawler or FST looked cool but on 1 month back order as well.  After digging through the catalog/online, I ended up finding Holley 750's are not as expensive as 650's.  I was surprised to see that so I started looking at a Holley 750cfm 4160 that I found for $385 but it was on backorder.  After calling in on that carb, I decided to search around a bit more and found an aluminum Holley 4150 770cfm Street Avenger priced at $505 and it was in stock with Holley.  After some contemplating, I decided to pull the trigger on it.  This one is about $175-$200 less than Ultra Street Avengers because of the cast blocks and baseplate (Ultra's are billet) but it has the aluminum body like the Ultra carburetors which are lighter.

-Vacuum secondaries
-Electric choke
-Quick-change vacuum diaphragm spring
-4150 dual metering blocks
-Aluminum main body, block and bowls

langss,
For my lug nuts, I currently have to use metric tapered lugs for the front wheels because I have the "1LE Mod" which consists of using 90's B-Body spindles and 3rd Gen F-Body 12" front rotors which have the later metric thread pitch.  For the rear, I currently roll the car around with standard tapered lug nuts.  I have to do final fitment on the rear with the disc brake conversion because I'm using a rear end that came out of a Camaro.

5th T/A,
Your assumption should be correct.  Aluminum LS blocks are about 125lbs lighter than iron LS blocks which are similar in weight to Pontiac engines.  Factoring in aluminum heads, intake and carburetor, I would guess around 200lbs difference on engine.  To go further on this subject, I'm bolting the aluminum engine to my original 4spd transmission and doing a 1" engine setback on the frame.  My setup will probably be lighter than most LS swaps you will see because I'm not running a big/bulky overdrive auto or T56 transmission.  Manual brake swap should be another 20-30lb taken out of the car.  This setup should be as light and well-balanced as you can get without going too crazy on modifications.   I won't be doing things like striping out the door structure or fabbing aluminum core supports like some of the racers do.  These basic things I'm doing are enough for me.

FormTA,
Thanks!  I was actually planning on doing one of the classic Holley carburetors with the gold zinc coating but this polished aluminum body 770 carb fell right in the same price range, is lighter and was in stock for sale.  Not what I planned on initially but I think this is working out for the better.

Thanks....I have several different sets of 3rd gen wheels and until I saw those on your car I had not considered them. I agree, they go very well with the color of your car.

For street-driven 67-81 cars, the 16” 3rd Gen wheels are a nice/cheap upgrade in my opinion.  16” tire selection isn’t the best but the offering for street performance tires is a lot better than what is currently available for 15”.  I don’t know of any Z rated 15” tires unless you go to a full race offering.

[/quote]Funny you mention that....I'm looking for some 16" tires for my 92 Camaro. I find the selection somewhat limited, but at the same time somewhat pricey. I'm sure I can find something that will work at a reasonable cost for a car that mostly sits.
