Building a hot 360

Can't wait to see how they run. I have a 68 Barracuda that came with a slant six. Front end set up with BB torsion bars and 15" disc brakes. Suspension control arms 100% new. Friend wants me to do the Hemi swap. This is a street only car for cruising and I'm not sure I want the hassle. Local machine shop can take care of the 360 block, friend can assemble it. I'm leaning toward 360 since I already have it. Any opinions?
