I was at a dyno this weekend trying to work on getting my blown (6-71) BBC running good. We did manage to get 500HP at the wheel (@5100RPMs) but after making another jet change the engine smoked the clutch.

Anyway...

It was reccomended to me to get a rocker arm stud girdle to strengthen the valve train. Not too many available for a big block though just wondering what you might use. I'm thinking about one from trick flow it's about $250.
