Is the 400m a totally different block from a 351? What's the difference? I might pick one up tonight for 75$ that runs. edlebrock intake and some kind of cam. What do you think?:SNSign:
I've seen a couple threads on here talking about 400m's in foxes. Do a search and you might be able to find 'em. If I was going to go to the work fo swapping in a 400, I'd probably just go with a 460.
I woudl go allt he way to 460 if you are gonna spend money on big block. the 400m is not that great and you will need to do some pretty significant modifications to install including pan change (oil pickup as well) trans tunnel clearance for C6 (C6 heavy power robbing trans) and dirveshaft sense the C6 is longer then C4 or t5. Also need some swap headers and new exhaust and motor mount bracket kit for big block. If you like the idea of the carb 400 go with cleveland setup which uses all same stuff as small block for install and will jsut need different pan and exhaust.
