Mine should fire on the dyno this week and the rest of the car is just sitting and waiting for it. It could be running down the track in 2 weeks if I'm lucky.

If you have any questions go ahead and ask. I seem to hit evey issue possible.

I have 2 LS Vega setups. One I had a generic LS plate just modified to for on the bars in the front.

I also have a 76 green Vega that originally had the regular V8 kit for a SBC. Where you weld the mounts on the body and the engine mounted brackets lay down on them. I had a plate made that laid right down on the mounts made for the SBC kit.

Here is a pic of each setup. Both were custom, the green one more than the purple one.

The plate isn't that bad it's the exhaust and steering that is killer.

I cant decide which way to go with mine. Mild build or take the plasma cutter to it and do tube chassis with a 6.2 twin turbo/powerglide 12 bolt combo. I geuss I will see what the money tree sprouts before I make that decision.

I was short one O2 extension cable on my FAST XFI this week and had one sent over nigh to the shop yesterday. It should have got there around 3 today so I'm thinking it should start up on the dyno tomorrow.

Anyone want to guess at a number?

Cam is 24x 25x and 625 625.

Running on a FAST XFI system
Custom 1 3/4 headers that will not go past dumping at the collectors


Here is some more engine ****.

Hey Rock,

I know you said "purple", but that looks blue to me. In fact, it looks like the Ford "Sonic Blue Pearl" (code SN) I used on my '72 LS-Maverick. Care to divulge the paint code?

Thanks!

Russ

It always looks total blue in pictures for some reason but in person its grape purple. Not a hint of blue at all in person. Don't know the code, it was like this when I bought it. Even had a rear plate that said "Welches"

Didn't spec the cam duration or mention nitrous. I'm guessing 575hp.

So far today we are at 605hp @ 6500 at the crank. They aren't done yet but I bet its pretty close. Should be fun in a 2600lb car. I'm pumped!

Ended up with 617 at the crank
