That cam will be super close too not to mention you'll either lose power or just move the power band. If the Z cam is already in there then I'd yank it out and throw a stock cam back in but that's just me. If its still just got the stock cam in there I'd leave it.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
