JE Piston

Im putting in a high compression piston in my 450, it is perfectly jetted now. Will I need to re jet with the 13.5:1 piston?

You shouldn't have to make any drastic changes.

I didn't. I only have about 3 hours on my new CP 13.5:1, but made no jetting changes and it runs great.

Good news. Thx Guys.
