[QUOTE="Cobra_Meth, post: 9652755, member: 54491"] When adding cams to these motors the compression drops, that is normal. Mine went from 175psi in every cylinder to 135psi in every cylinder after with less than 5% leak down. It really sounds like the cam's were not degree'd when you installed them to the cam card specs. I had the exact same problem you were having and it was the cam's not being degree'd properly. I had the motor in and out 3 times before we got it right. Now the car made 683hp, 622ft lbs std with the supposed junk cams. Hopefully you went with a good adjustable cam gear some of them out there can be a real headache. [/QUOTE]
