Ok, considering some heads for the 383 'maro engine. Be nice to me, I'm a Ford guy!!!!

Looking at 64 cc, for a CR of 10.8:1--or so sez the shop doing the engine--I haven't seen the engine yet, supposed to be done in a week or so. Anyway, assuming the builder is correct (he is a good builder btw), I suppose about 180 cc runners would do.....However, I plan on playing with things a bit, solid roller cam, and of course with the high CR it will be another E-85 fueled engine.... It does of course take a lot more fuel with ethanol, no problem there, a 750 or 830 reworked for ethanol should do fine (?) but maybe I might want to go to 200 cc on the heads and a tad over .500 lift on the cam???

I know, hard to say without the piston specs and squish data, but help me do a bit of guesswork, ok????
