@redoxide got my imaginaton going on a hypothetical engine swap i've had going in my head for awhile now. Let's say you have a '40 Ford with no engine and you want to swap in a OHV engine and you have accsess to the same three engines. A first generation Hemi, an Olds rocket engine, and a Cadillac (331-390) which would you pick? Would you go with the Cad like @Moriarity has, would you go with a Olds Rocket like the Bob McCoy (The real Macoy) or would you go with the Hemi? I've also heard where a 302 Jimmy straight six was popular in these cars at one point too. and just for fun lets make it a poll too!
