Bunch of Noob question from a Dutchman

POk will it also work good with the original stall converter ? And i recdently bought a chrysler 8.75 rear axle. What will work with the standard gears that are stil in there ?
And what are the consequences of keeping the original stall and rear axle, but still getting a higher compression and different cam etc like you earlier mensioned ?
