650HP stock block

Ron,

Are you running a solid block now, or wet?

We raced a 9.20 bracket for 3 years and the only parts we broke were three holes in the cylinder walls. Fords are notorious for thin wall cylinder castings. We sleeved the two cylinders and ran without issue another 2 1/2 years.

We replaced bearings every year, and piston rings too. These are cheap and easy to replace anyway.....

They key to not breaking parts is to eliminate detonation. Look into water injection. There is no better way to control combustion chamber events than water injection. It is simple, painless, it allows you to run much higher static compression than you could ordinarily get away with, and it keeps your combusion and exhaust system "steam cleaned".

Other than controlling the oil inside the crank case, there is no other single thing we did that provided access to great et's.
