Sell it, buy the kid a 350 and pocket the change. If it's a DZ 302 complete its worth some change. Don't ask me how much but definitely worth more than a decent 350 or 305.I believe 302s were only in Z28's from 67 ( 67's did not say Z28 but 302 on the fender emblem)68 & 69.... Gotta be worth alot to a first generation Z28 guy, especially if the car it came out of is still alive..
AND I am not afraid to say my favorite car of my youth was my 73 Z28, and I had an A12 Super Bee before it.....
