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.

Actually I have no idea. I know they are AL, and I know they have square ports on the exhaust side. (oval?)
If you have oval port heads try www.competitionproducts.com.The stud girdle sells for $163.00 plus shipping.You really don't need one unless you are running a roller cam or a high revving soild cam.
i have ran my 548 blown big block chevy iron head soild 720 lift roller cam with 240 psi on the seat and 680 open and have not had a problem and this has seen7000+rpm s may times in the last five years and have built may with out on iron heads with no stud girdle but there are may out there if you think you need some. i do not think. so but here they are . crane .jomar. brodix. reher morrison.howards and there are may more :whacked:
Ok I understand your opinions on the stud girdle. I probably don't need it, especially since this car is just street driven at a snails pace most of the time. I'll save my money for a clutch which will be my next topic. :LOL:
