Someone needs to start re-casting 340 blocks

there is only emissions rules for cars that are 1976 and newer. anything before that, they could hardly give a crap about. and even for the stuff that has to face the smog test gauntlet, if your stuff runs clean (and it should) it's a non issue.

Just tripped over this on the Holley website. 1965/67 and older??
