Hello. I am sure this is posted somewhere else but am new to this forum and old Chevys as well. I recently purchased a 1951 3100 with what appears to be the original 216 engine. It has a factory 4 speed on the floor. I have the opportunity to buy a rebuilt (and hopped up - cam, dual carbs, split exhaust manifold, electronic ignition) 1955 235 that has been redone to use unleaded gas. My question is, how easy is the swap and will it bolt right up to my stock 4 speed transmission? I want to keep it looking mostly original (with some period correct upgrades for performance and driveability) but don't want to change out everything. I will be keeping the original 216 put away to keep with the truck if I ever sell it.
Thanks for any advice/help you can provide.
Frank
