[Mineral Gray GT]

I'm looking at picking up some Crower stage II blower cams and Comp Valve Springs from a member on here. If i degree the cam properly, will I have PTV issues with stock pistons? I've read every thread on here about PTV contact issues and it seems like most all NA cams have PTV issues but I didn't know if it made a difference being a blower cam.

What are the cam specs?

Duration and lobe separation angle are the major factors that determine if a cam will work. You may want to visit Nick at MHS. He has already done all the research and knows what will work on a stock 2v.

These performance Level 2 cams from Crower are designed for individuals who require more power and an extended rpm range. They provide excellent low-end and midrange power for spirited street and off-road driving and mild marine applications. These cams work well with stock or near-stock engines and drivetrains.

My first opinion would be that they are to "big" for a stock 2v. They will probably fit but require modifying the install angle to get marginal ptv clearance.
