I currently have a 2.8 kenne bell on my 2008 Gt500. I am looking at going to a 4.0 and wanted to see what some of you guys have used and how you like it. My car has a built motor. The engine has a ford gt block, Billit crank, H beam rods, Pistons, Head studs, Ported heads, cams, etc etc. I'm told that whipple is the way to go due to the Kenne Bell making alot of heat compared to the whipple. If anyone has used either, let me know what you think. Thanks!
