Hey guys, I'm looking to compete in the true street division next year and am pondering about cams. Now my question is, I'm looking for a cam with a .550 lift and around a 242 duration. Now my question is will I have valve clearance issues?



Thanks
Al

I believe anything with more than 232* and .550 will need a competent mechanic to degree them and check PTV. In other words you just can't drop them in and go I would degree and check PTV on any cams myself.
