purple cam p4120231 wanted

Not a bad find there George. (Are you sure it’s for a small block with the mention of 350-361-383 after it?

The MP cam is 5 degrees larger @050. The earlier cam is on a 112 vs the MP’s 108. While the narrower LSA will create a rougher idle, it also delivers a lot of low end torque over the 112, which will have a smooth idle.

To the OP, give a call to a cam grinder. Call up Schneider racing cams (for example) and tell them what you told us. They can cut you a cam but it’ll not be an exact copy but an improved one.

Comp Cams offers their version of purple shafts as well. They feature a small split pattern on there cam.

Food for thought.
