I don't remember what smog junk was on them, I'm pretty sure they didn't have cat cons. But they still had the same low compression, small intake valve, no cam lo-po motor.
Don't mind me, I just hate the mid 70's, late 70's "muscle cars".
the EH1 360 ran nice.. double roller chain, big thermoquad, 727 with factory shift kit and a 3.55 gear. little tuning got them into the high 14's at the track..
