So I have the 5.0 efi followed with a e4od trans. I am wanting to drop a 460 after I do some work to it, but putting the 460 in. I have some questions before I put it in. I've dont the research on what I want to do to the motor but what I'm consirned about is if I should go carb or go efi. If I go carb what computer would I need if any or could I just have it in without a computer. If I go efi I'd need a computer and I would probably pull the engine and trans from a f250/350 and also pull computer but what else would I need? I'd like to still have ac and heat if possible. Also would it be easier to run the e4od or a c6? I know I'd need motormounts, probably a larger radiator, headers for sure but what else would I need, every time I look I see people do the swap but I don't see enough info on how. If you have done it please let me know and give me some advice. Thanks. If you need more info about my truck ask please.
