What's going on fellas... I figure I'd post up some pics of my 86 Ttype build i'm doing. I got the whole swap LY6/4l80e out of a 2008 conversion van with 60k. Had the heads ported and installed turbo cam with LS9 gaskets. Will be running a precision 7675 turbo and planning on e85 with dual 340's 8an lines an kit from Racetronix.

Body should be coming out of paint this week so I can start to test fit and play.

This is where I'm at right now...running the truck compressor and crank pulley hoping I won't have to notch much on the frame. I need to space the GTO accessories 3/4 out to line up with the truck crank pulley. I'm going to run the pump spacers and the driver head spacer from ebay to do this, but still need to come up with something for the alternator though.

Have you had the engine in the car, yet?
We are doing an 85 G-body, and found that the GTO alt w/ the funky nose on it, hits the steer box. Even w/ another alt, the clearance is <1/4". We are now changing to the Holley access mount.
On mine, I am using the truck balancer, Vette accessories, 2010 Camaro wp, [pump requires no spacers], w/ tubular spacers. Clears, but with limited space at the gear box fittings. [Using banjo fittings on the box, and on the Hydraboost.]

Hopefully the fun begins this week when I get the car back. It's suppose to finally get cold down here in Florida so we'll see what happens. If you have any pics or a link to your build please post up and thanks for the info!

I was able to use the truck alternator by trimming three of the case fins down next to steering box. Water pump, alternator, and PS pump all spaced 3/4 out to match truck crank pulley and AC compressor. Truck compressor fit with no notch, just a little message to the frame for extra clearance.

Where are you mounting the turbo?

This build is awesome! By the way, which motor mount are you using to clear the truck ac compressor?

Thanks man! I'm using the spohn mounts.
Cool, that's what I was thinking they looked like. I have those mounts sitting on the shelf for my swap as well and I'm glad to see they are going to work out well. Also, which oil pan did you use and how is the clearance?

I used the Holley pan, it fits oh so perfect.... also sits higher than the frame for ground clearance.
