I shoot for between 10.530 to 10.80 to 1 compression ratio on my non ethanol 91/93 octane pump gas BB builds with aluminum heads, that has work very well for me and my customers up work twocents


Thanks for the advice unfortunately I have no access to non ethanol in my area.

If there are any boating areas around you check gas stations in that area for non ethanol gas.

In theory, there is no difference between theory and practice. In practice, there is.
