Kind of have decided to put a Muncie M-22 behind my BBC 496 which has been estimated by Smith Racing to be near 700 hp. Solid roller Cam is .652 lift. Rear end gears are a 3.73 Eaton posi. Do I get the close ratio M-22 or the wide ratio??? A friend has a complete original GM 68' M-22 (all the stamped numbers match the M-22)that would need a rebuild...he said I could have it for $300 bucks....good deal??? Do I buy it from him and have it rebuilt with those nice Italian gears how much would that cost??? Or would it be better to just buy a New AutoGear SuperCase all ready to go??? Found one of those AG SuperCase complete units from T&B Trans for like $1800.00.

Input...Opinions...all the like please chime in!
