Default Sort of C4 tech related, C4 drag car

This is my 1990 C4 drag car that I have been working on all winter, I do not have a tech question but thought some of you guys may find this interesting.

-515 BBC HP TBD but should be between 700 HP and 1000 HP
-Holley EFI
-12.5 compression
-385 AFR heads
-Solid roller .790/.775 lift with 278/286 duration @ .050
-2.5" headers
-Vacuum pump
-2000 CFM throttle body
-Mutli port injection
-1.76 powerglide
-4.29 gears
-2400 race weight

Expected ET from 8.0 to 8.8, best educated guess ET 8.6, will find out soon.

Many pictures

Holy crap.. That thing looks like it's going a thousand miles an hour, parked in your garage!

Nice ride..

Too fast for me, but I'm glad someone is doing it. I like to watch!

That is a work of art you got there. Just one question, why not retain the full clamshell hood?

It is, it is a Mustang II style of front suspension. Next year I may go to a strut style of suspension, time will tell.

If you can squeeze a coilover in there and it works, might as well leave it !

It has coilovers in it currently, that is why i am not too concerned. I will run it as is and see how it works and if i decide to clean it up and save some weight will change it over next winter.

I'm in awe. I'm sure we'd all love to hear a sound clip.
