Not all vehicles need to meet the same criteria. Some states are different too. What state ar you in?

Thanks Ed.I posted the mods I have done.77 350 impala coupe fast back rear window.My goal is to sooner or later take it off the streets and use for 1/4 mile use.I live in Calif where they dont B/S about smogs.The numbers are being lowered to pass every year here in Calif. I went to pick the heads up today.I was told they were in good shape.I dont know if it was dog piss or if the heads were used as boat anchors.I passed on them. Thanks for your reply.[/img]
