Proposed cam specs

Good info all around.

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.

The truck manifolds that I'm running are '72 360, which are the same up through the late '70's, maybe '80's, before Magnum.

I'm seeing 2 1/4" outlets on both sides. The thing that I really like about the manifolds is that they do not raise on the driver's side, so they don't nuke spark plug wires, even without any heat shield and are easy to change plugs on, even warm.

I'll get some pictures (and numbers) of what I've done on mine, but I really like them for the street. The best thing you can do is get a set from a truck and cut the pipes where they start to go back, to use what you need for your exhaust. I managed to modify the clamp to clear the trans brace, but you could modify the brace as well to get it to clear.

It's just basic cutting and material grinding to gain clearances on the driver's side. The passenger's side was drop in.
