I6 to V8 swap questions... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am fixing to pull my blown 250 from my 77 shortbed work truck and replace it with a 350. I want to keep the original 3spd manual trans. Can I use the flywheel from the 250 on the 350? Or do I need to get a v8 flywheel.. The flywheel, clutch and pressure plate isnt that old so I was just going to use it if I can. thanks! also I am guessing the rearend has some pretty low gears because of the six, what gear goes good with a 350, 3 on the tree??? Dont really care about MPG, just want to be able to pull a small trailer and go 70mph if need be.
