" From: Wrambler242@xxxxxxxxxxx " " I forget which pistons have the depest stock dish, but I can find it by searching it out. speed pro 677p iirc, 17.5cc? " If I leave the block standard bore and use the deepest dish as cast pistons that should keep the compression right at 9.2-1. yup " I just need to pick a cam that bleeds off a bit and rpms out to about 52-5500rpm. you may not -need- a larger cam. if you spend a little time smoothing the sharp edges [hotspots] of the chambers and maybe piston dishes and run a slightly colder plug you'll probably be fine with the stock cam. 9.2 isn't a -big- jump from 8.8, and you can bet they were conservative. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
