The pres of the Rochester Z club has a 73 240z. he had a supercharged fi 2.8 in there, and his ls1 plans were sped up a bit when his crank pulley and key broke last year at an auto-x/drift event (rj was there i believe).
just a sound clip basically, but I’m sure it’ll be at the glen a ton this year, he’s always doing trackdays there.
