Could this cam be holding me back?
Well, I couldnt leave well enough alone. I put a smaller pulley on my KB.
It made 15 psi. I ran it for a week and BOOOM ( Blew a HG)
The AFR when it blew was 12.3@WOT. With the 10 psi pulley AFR was 11.8@WOT
Once I went thru the motor I found out I didnt have an E cam. It was a Crower #15512
I tuned my injector timing (With TwEECer) based offthe E cam profile.Could this be
why I blew orwas I just running too much psi????

you blew the gasket cause of pressure. make sure everything is flat, and install a pair of quality gaskets and you should be fine.
have you found the specs on that crower?
