Were cars of mine -- I had the Vette which is an original 427/400hp tri-power car for many years... and used to do the NCRS 'crap' with it... but also like to DRIVE the wheels off my stuff -- so plopped in a fuel injected 502 for 'driving'.
That car was rare in that it was the 400hp version - with A/C - P/W - Leather - Speedminder - Telescopic wheel - 4 speed - N14 side exhaust... Not often do you find major motor with a drop top and A/C... but it belonged to the car dealer in my town - and when he ordered it for his personal car - he ordered it all...

The Camaro was a Z/28 RS - with endura bumper... but 302's are B O R I N G so I dropped in a 350 HO 330 hp crate motor and a 5 speed and did disc all around so I could actually drive it and have fun. That's when the hot rod urge hit -- and I switched to my Nomad and sold both the "nice" cars before I could cut them up.... LOL
