Had a 68 RR 383, put headers on it straight pipes with GTO resonators at the end of the exhaust, Installed 430 gears and a short Hurst shifter. Rebuilt carb, Installed a Mallory distributor and all associated parts. Installed 12" ripple Walls in the rear. Had it dynoed and was putting out 410 hp at the wheels. There wasn't a 440 around that could touch me and I beat most auto hemi's! Track times were in the low 12's.
I’ve had mine for 26 years, restored it 12 yrs ago. Wrong seat covers, should be blue. Steering wheel is also wrong. Door panels also s/b blue. Shifter was a reverse lockout with black knob. Overall this looks good, a few tweaks to make it 100%.
While I was waiting for my ordered '77 GP to arrive, the dealer lent me a '68 Plymouth 318, auto, looked like this to drive free for a month... it barely made it... was likely scrapped after me...
