Maybe I should rethink my decision on using flat tops and thus 11.6 CR. If you can make 533+ HP with Dished pistons.... That may be the way to go that way I can for sure use pump gas....
...........You could also go dished but I think if you do the idle will be a little rough as even the smallest dish puts it down to 10.2. As far as the cam....
Moper, Can you help me out with this comment you made? So if I go down in compression and keep the bigger cam in the 251/257 @ .050 range it will idle differently than with the higher compression. Sorry if this is a stupid question.....
