Anyone want to talk Chevy! LOL
For me, if I was upgrading that Camino, as a min. It would be the old boring basic 350/350/3.55’s. Mild cam and basic hot rodder package. Intake, cam etc...
I had a ‘79 S/S ElCamino.
Black w/ red interior.
The 305 in it was smogged down and gutless but it did drive everywhere at anytime for hours on end with decent mileage. Added a set of mufflers and it was all good.
