So now I'm starting to think things over.
I think that I'll sell the carbs and buy a birdcatcher.
then sell the eagle crank and rods
and buy a callies magnum crank and oliver billet rods
and last but not least use e85 fuel
now two questions. if I swap from the 4.5 stroke to 4.25 stroke and want to use the JE pistons I have I need a rod that is 0.25 longer then the rod that I would use with the 4.5 stroke crank RIGHT? now I have a 6.535 rod so the new would have to be 6.785, and because oliver do not have a "shelf" rod in tha messure the next would be 6.800 that should not be a problem if the block is 10.200 and not 10.180 like it sayes in the JE catalog. they also have a shorter rod 6.735 would that be better?
Second how much HP can a Dart big M block handle with the ductile caps? (no billet).
