Brainstormin' 440 vs 5.9 ...

IQ52's low comp 440 mule laid down 450/470 with a MP 509, M1 single plane and an 850 with headers. which i think is a respectable number for something basically thrown together.

but the devil, she be in the details... a set of ported 516's flowing

.100........85/62
.200......160/132
.300......210/182
.400......237/203
.500......250/216
.600......261/229
(intake/exhaust)

so, i could see you making similar numbers with a more modern cam grind and the torker with a little attention to the heads.

but sometimes the stone axe approach just flat *** works. the MP grinds were good for what the motors were and to some extent still are and head flow is king. hang them thangs open and twist her tail and see what comes of it.
