I need help?
 

I was wondering if a B cam can be installed in a stock motor with no piston to valve problems.

There is a kid around here with a B303 Cam in his motor...and he said he hasn't had any problems with anything. So my assumption is no you shouldn't. Although...i asked about cams on here...and i was put in my place when i was told not to cam a stock motor :D

Sure it can, an "E" cam has even more lift, and guy's install that as well all the time.

A "B" cam on a stock motor will slow you down though, without heads and an intake, you should stick with your stock stick.
