All steel down to the bumper brackets, cleaned and sandblasted underside. She had a 331 SBC with the 292 castings, turbo heads, ported and polished by me with 2.05 intakes and 1.64 exhaust valves. Ran a flat tappet solid cam and an 800 Holley DP. I think it was about 11 to 1 motor, I built it in the basement., she ran 11:20s at 123 all day long. Had an old Doug Nash magnesium 5 speed with a Hurst vertical gate shifter and a 3 finger Ram clutch. Can't really say I remember the launches till I got into 3rd gear, it was pretty busy till then. No electronics launched by sound, had a Moroso cable driven tach. Had a 12 bolt nova rear with 4:88 and Summers spool and axles. Set up my own gears after two failed attempts by the local so called pros, no failures after. Ran Hooker adjustable fender well headers, I think they were 1 7/8". Wow haven't thought about all that stuff in a long time, amazing all details are still in my head. Sure wish I still had her!!!
