Default Highest compression with...

Stock pistons? Without changing the bottom end, how high can you get your compression with heads/cam/gaskets?

Want to take advantage of an E85 setup next year

14:1?

If you get a head with a small enough chamber, anything is possible.

Without ruining quench and getting a real nice DCR I think it would be a great setup for E85's high octane. I didn't think you could get much higher than 12:1 SCR with a 59cc head without changing pistons?

What kind of numbers could you get away with on a 105 octane fuel anyway?

Answer is in here: https://ls1tech.com/forums/generation-iv-internal-engine/599321-there-47cc-heads-other-ways-get-close-12-1-cr-5-3-a.html

Wich means the 14:1 is for 325 CI engine. Hm..... that's close to diesel setups. All alluminum diesel engines are unknown to me. Makes me kind of worry.
