Currently it's the slant 6 with 3 speed column shift, all original. I do have a 318 Poly I'm building for it though and have also adapted a T-5 5-speed to that. Attached is the Poly in stock form showing the Ford headers I adapted. Once I get this in the truck and get everything working well, I'll swap to the manifold shown for a short while. I expect to pull the engine back out in winter and do a complete (performance) build.
Thanks for your interest.
