Anyone tried stuffing later 460-FI into older carbed truck

[JC]

My old 460 bullnose in my avatar hasn't ran in 20 years. Its froze up. It has a 460 carbed engine. I just picked up a 97 F250 wrecked at auction with 80k miles.overdrive ect and runs fantastic. Wondering what sort of jobs this would be. Any of you tried this out there? I even considered dropping the bull nose on that newer frame. Seems like a lot of work. I know I am going to regret it if I sell that truck

Yes, someone has. Or is. Me. In Big Blue. And, Bill/85lebaront2 has done it to Darth.

If you are a glutton for punishment you can read all about it, and LOT'S more, in Big Blue's Transformation, which is now to 78 pages and growing steadily. Or, I can give you the info in a nut shell and you can ask questions of Bill and/or me.

But first, you said you bought a '97 F250, presumably with the 460. And you said it has overdrive. Is that an auto with OD? Or manual? If auto it'll be the E4OD. If manual it'll be the ZF5. However, the big question is what ECU yours has - EEC-IV or EEC-V? The IV will be bank-fire and no mass air flow sensor, and that looks to be what you have, although Bill can probably answer the question just by looking at your first pic. I ask because both he and I are using EEC-V with sequential injection and a mass air flow sensor. So our wiring will be slightly different from yours, assuming yours is EEC-IV.

Anyway, Bill is running an E4OD in Darth and I'll be running a ZF5 in Big Blue. The EFI 460's have completely different intake and exhaust manifolds from the carb'd engines as the ports in the heads are different. So you'll want to swap everything into your Bullnose.

Or, you can convert the '97 to Bullnose fenders and bed, but leave the interior with the later dash. It'll look like a Bull, but will take less effort.

That's a bank fire speed density system, EEC-IV and a MAP sensor.

Thanks, Bill. I thought that was the case.
