Gscalifornia, I am going with the 455 because I have to tear apart the 350 because it ate a rag and has cotton strips in the oil pan. Still amazed that it didn't blow up. Anyways, I have to take it out and clean it and I'll either sell it complete or put it in one of my other projects. I've got the 455 together but I'm going to break the cam in on a different frame that I have while I take the 350 out and get my tr400 trans cleaned. Gears will come after I get the engine in.
