460/460 swap...

Hi all! And yes, I want to swap out a 460 for a 460.

I have a 77 F250 that broke it's camshaft. Long story, it's here in another thread. My question is, what years will fit without modifications? I just need my truck, and can't afford the Long block I want right now, the economy being what it is, and have found a butt-load of 429's and 460's online, but most of them are a bit newer. I'm reasonably sure the Fuelie version won't work, but will the '85 and earlier ones fit?

Thanks for your help!

cool Re: 460/460 swap...

1968-1978 engines are internally balanced, while the 1979-up engines (with the D9TE-AB cylinder block) are externally balanced. Which version engine do you currently have with the snapped camshaft? What is that block's number? Is your truck manual transmission or automatic transmission?

It's the original engine, so I would have to say it's the internally balanced version. It has a C6.

I'm not too concerned about internal or external, I just want to put a replacement in that will accept all the pulleys and bracketry, and the intake and exhaust manifolds, if there is any difference there, so I basically want to know which year engines to ignore in my search. I'm looking at 2 84's and a couple early 90's right now that I can hear run, I just don't want to drive 75 miles to look at one that I can't use.

1968-1987 should work for you. (All OEM carburetted engines). 1986 & 1987 models will have one accessory bolt hole on the end of the head(s) that is of the next larger size than the 1985 & earlier accessory bolt holes.

The 1988 & up engines are 460 FI engines and have a different top end (different heads, intake, and exhaust manifolds) and making them work is a bit more involved. For example, the earlier carburetor-style intake manifolds will not work with the FI heads, and the heads will not properly accommodate carburetor-engined exhaust manifolds.

Thank you Paul, that's exactly what I was looking for. I just bought a fresh 79 460 out of an E-350 box van that was parked due to California's ridiculous licensing fees, then scrapped due to an over zealous code enforcement officer.

According to the paperwork, it had 7,143 miles on the rebuild. 500 bucks, and it came with everything from the carb to the pan, fan to front drive shaft yoke. And I don't even have to clean it. LOL
