If you want a kick in the pants, have your 2.5 heads cut to 34 cc's. Jay said you'll feel the difference. Well, after installing and driving around slow to heat the engine up, I pulled back to the dock and re-torqued the head bolts. Went back out and eased up to about 30mph and then hit it. I jumped to keel walk speed before I was ready. Amazing the difference it made. Sure glad I did the change over, most premium gas in Oklahoma is ethanol free.

Jay, thanks again
