I seem to have hit a brick wall at 350whp with my rb20.

I was thinking maybe my stock rb20 cams are holding me back.

I have heard that rb25 and rb26 cams can be swapped into the rb20 head. but i never found a right up on it.

what needs to be done? do I need to get the cams out of a specific engine?
what can I expect from doing a bigger stock cam vs pon cams?

I am trying to get to 400whp on e85 with this setup.
