and re: Kwik AC bracket. I just ordered a VA kit for the nova, but couldn't justify the $150 extra for the couple pieces of tubing and plate aluminum (which doesn't include the $80 in belt and f-body tensioner you have to buy w/ truck accessories). Shouldn't be too difficult to fab one for much cheaper.

and don't forget to get the thing weighed! I'm interested to know the difference.

CFster first off I reall like the build!!! Very helpful posts. So I have read all the posts on your thread and noticed a few? I have. I have a 64 Impala and I am also putting an LS3/4L60E in.
I noticed a flexplate and spacer. I have a new TCI tranny and had to order a new flexplate to bolt up to the tourque convt. Dont know if i need a spacer?

You asked about the EVAP/charcoal. Did you have to install it?

Then the steam line to the radiator. I have read in other threads about this and I have bought a BE COOL cross flow radiator. Do i need to weld in a port or can I run it to a different location?
I have more ? but this is a good start. Thank you for your time and knowledge

No rubbing issues whatsoever. Part of that is probably due to the revised camber curve from running the AFX spindles. When the suspension compresses the top of the tire moves in so it can't hit the fender lip.

Yeah I think you have to use the spacer with an earlier style flat flexplate.

You asked about the EVAP/charcoal. Did you have to install it?
Nope, didn't run EVAP or charcoal canister.

I ran mine to the radiator, which I had built with a fitting. But people also drill a hole in their water pump and put a fitting there, or put a fitting in the upper radiator hose.

I believe I have the same size steering wheel has you currently have. What dia is the one pictured here with the paddle shifter? Does this allow you to keep the trans in gear behond the programmed RPM shift points? Looks like it will be alot of fun with the paddles. Car turned out GREAT congrats!

Nice ride!

You have a picture of where you mounted the computer and ran the harness? Just trying to get some ideas.

14" with a flat dish (necessary because the Shrifter is a couple inches deep). As far as I know it lets you hold a gear as long as you want, but I could be wrong.

Thanks.

You can kind of see it here. Things were still pretty messy in this pic, but it's mounted on the inner fender behind the right headlight. You can see the main harness runs behind and comes out near the right side hood hinge and runs over to the back of the motor. Wires to the battery and ignition are run under the upper radiator support to the other side.

Got some engine covers on it. I haven't really figured out what color scheme I'm going to use, but I'd like the covers, intake tube and possibly a radiator fill panel to be the same. I'd like to find somebody who can put some lettering on the covers - like P O N T I A C and then L S 3 underneath or something.

Decided to go with a slightly taller tire (45 vs. 40). I think they fill up the wells a little better and made a big difference in ride.

Beautiful car and nice swap. I am right in the middle of an LS3 going into my 72 Vette. I like to see what others are doing. I used the Kwik brackets for the Ac and the PS and Alt mount. They are nice brackets.
