okay, If you're looking for a mild build that will run AC and idle nicely at 800 RPM, then really, why are we talking about spending money to hack into his MP crank, if he already has a 440 block sitting there????

You've said you have an MP 3.75 crank..... And you've said that you have a 440 block sitting there, but only a cast crank for that. The MP crank IS a forged 440 crank (426 Hemi and 440 use the same crank)! I know this started as a 451 build thread, and trust me, I love the 451 combo, but..... I'm going to suggest that using the MP crank in the 440 block is his best option.
