I love the SMB Chev's. Best engine I ever had was a 327- 350hp in a 67 vette. She ran like a swiss. The hyd lifters and 11 to 1 compression made for a great combination. It was good on gas also with a 355 rear...but only if you kept you foot off out of it which was kinda hard to do at times. The good old days, Remember?
