Can anyone tell me if the clutch disc I have between my 225 and SM420 will work with the 4.3 I am going to bolt to the 420? I am almost positive I'll have to get a new pressure plate which sucks but if someone can tell me otherwise, that would be great. Also, I'd like to put a hydraulic clutch in as part of this swap. Does anyone know of a 90 degree Chev. bellhousing that would have a provision for a slave cylinder built in? Someone told me to check late model Camaros though I believe the engine/trans mate with each other15 degrees off center on those (the trans is pointed towards the drive a little). Chevy trucks maybe? Any ideas? Thanks as always!
