Re: Compression and cam timing
You CANNOT run 11 to one compression on 89 octane, under ANY circunstances. 10.5 to one with 91 octane will work OK. To get a mild driver camshaft, just spread the lobe centers out to 112 or 114. This will tame it down alot. By the way, flat top pistons on a 347 will give you around 10.5 to one, which is very good.
