Thought you guys would like to see this. After two seasons on E85 I took the heads off and started to disassemble for inspection before it gets sold.
Engine is SBC 4.145" bore x 3.800" stroke with SRP forged flat top pistons. This is a solid roller cammed engine that is 11.4:1 compression and has been run almost exclusively on E85 since spring 2007. It did have 6 months run time on gasoline before the switch. I was surprised at how clean everything is -- I have NEVER seen pistons this clean after 2 years of use.
There was no ridge at the top of the cylinders, and no scoring or other signs of a lubrication problem in the bores. Engine has 250+ quarter mile passes on it and 15,000 street miles. I cruise on the freeway at 3400-3600 RPM and do NOT take it easy on this thing.
