Hello all, as promised, here is the build thread (more of a build summary really).
A bit about the car...

The engine block is a 1972 ls5 two bolt main 454, .030" over
Brodix rectangular port BB2 heads
Comp cams hydraulic roller .557 lift
9.6:1 compression, forged pistons
forged crank and H beam rods
RPM airgap manifold
850 double pumper carb
lakester headers
aluminum flywheel
mesierre (sp?) electric water pump
500hp, 530 ft-lb torque on pump gas

Tranny is a 1975 super T10 built by Dave's 4speeds

Rear end is a 1999 mustang cobra 3.27 posi, fully rebuilt

I built the car with my dad in his personal machine shop (bridgeport, lathe, tig, etc...). The project started in November 2011.

I grew up racing motocross and karts (raced 125cc shifterkarts professionally), and we always made a lot of our own stuff and did our own engine work.

This car was my idea, I designed it, and led the project, with dad helping and advising.

For the build, I'm just gonna post pics. I'll be happy to answer any questions. Enjoy!!

To start off, here is a rendering of the CAD design.
