Proposed cam specs

Hmm, no headers, but I have purchased a pair of 340 manifolds... one side is 2 1/4 outlet, the other side is only 1 7/8. :-( Gonna have to find me another side (I forget which one i need) I wonder what size outlet is on the 360 truck manifolds? Sounds like it may be do-able with a little grinding, I have power steering, 8 3/4 rear.

The company is Oregon Cam Grinding, located in Vancouver, WA across the river from Portland.
