big block to small block baracuda

Welcome to FABO! I guess my first question is: why not just build the 383 but since this is your thread, I'll answer YOUR question! Just like any other engine swap, you'll need the engine complete with all the brackets, pulleys, manifolds, etc. You'll need a small block K-member or conversion mounts, exhaust system, cooling system, wiring mods, and a small block 4 speed bell housing with Z-bar.
