10 sec. 318?
The car was just super stock springs with adjustable snubber and sub frame connecters. All steel, no glass. just rear seats removed and battery moved to the trunk to lighten it up. Ohh and some pretty light wheels.
The bottom end is a 318 forged steel crank, stock rods(polished beams and A.R.P. bolts) and 20 over pop-up pistons and the block was prepped for a roller cam (630 lift?) roller rockers and the rest was the W-2 heads and intake.
With Caltracs and a little lighter car, this combo would have been in the 10:80's easily.
You can't build it yourself for under $8000. You will have $3500. in trying to find W-2 heads and the roller rockers.
