Thanks Guys!
I'd like to hit the 1K mark and at least run some high 5's in 1/8 mile.I have more than enough turbos as long as the block will hold it. With a SBC 409 on 175 shot I ran 6.20's, so I think it's do-able.
Next couple days I have to finish the exhaust, cold side, new fuel system, and start tuning.

A little update.
I finished everything and took it for a shake down around the block. Everything seems good. Now I need to drive it and let Holley do its thing. Unfortunately, it's been raining for the past three days. I decided to upgrade the fuel system with dual 450's.

That looks great!
How is the car doing?
If you have a chance can you take some more detailed photos of the engine bay, accessory brackets, header clearance, coil mount, etc. I am working on my 72 TT build and any photos help.

It's doing great. Just been street tuning. Throwing some new shoes on it tomorrow. The old ones are getting loss at 110 mph (18 psi). It's been too hot for the track and now our 1/4 mile is shut down till next year, due to the flooding. I'll get some more pics this weekend.
