When I started my mega block build I bought a Callie's crank.. paid $2400.. I wanted a crank that would handle 1500 hp and the callies unit was the best one for the money.. that build was getting everything new.. mega block, callies crank, B1m/c heads(full porting) T/D rockers and a few other new parts... but I ended up selling it all due to rule changes.. mopar people are cheap.. they want the best parts for free or close to it.. as said.. power cost....
