My 460 is tired. It is in a 1991 F Superduty (F450) and it consumes oil past the rings. I want to understand what years of the 460 are drop in replacements. I know they are built in Lima OH from 1968 and 1997. I know some are fuel injected and others are carbed. I want to find a used engine and swap.

I would like to know it there are differences (that can mess up my swap) over the years. I am targeting a 1991 truck. So would a 1968 fit and pass smog? I am guessing there are improvements and the answer would be “no”, but what is the story here? What years would fit? Also the engines out of cars, motor homes and trucks may be different?

What does a doner engine look like???

Thanks

PS

I should add I know that EFI started in 1988 (is this only an intake manifold and EFI unit or were there head and block differences?) and that there are 3 head types, Chamber size (C8VE/C9VE/D0VE) 75cc
Chamber size (D2VE) ~99-100cc
Chamber size (D3VE/E6TE): ~93-95cc

But I don’t know the years for these changes and I don’t know if I should avoid one or more. I do know I need a “mule” not a race horse, so 8:1 compression is probably good while 11:1 is unworkable with pump gas

 

The intake and exhaust port locations changed for EFI engines so anything pre '88 won't bolt up to your exhaust manifolds or intake.
EFI engines start with E7TE heads and we're updated to F3TE heads in 1993.

What little I know about fuelie engines is that F3's have a bigger intake valve and better quench.

 

Far easiest is an 88-97 EFI engine. Installed in trucks, vans, rv's. Vans and some rv's used more of a center sump oil pan, trucks rear sump. May not be an issue. Some van motor mounts different but easy to swap what you have. Van dipstick tube longer, can cut to fit. I've pulled 5-6 of these from trucks, vans, rv's. No difference in engine/efi stuff other than the head casting change (I think piston change also same time). I can't tell a performance difference either way. As mentioned earlier, older pre-EFI engines would require head/intake/exhaust manifold swap as the carbed and EFI combos wont interchange. Vans also have the Saginaw p/s pump and bracket if interested.

 

460: 1968/78 and 1979 with a block casting number of D1VE-6015-A2B are internally balanced.

1979 with a block casting number of D9TE-6015-AB and 1980/97 are externally balanced, have a weighted crank spacer.

The flywheel (flexplate) and harmonic balancer are specific to internal or external balance. All 1968/82 460's came w/a C6. M/T & 4WD not available until 1983.

No 460's in Passenger Cars after 1978.

 

I have been looking around and the engines I can find kind of fall into 2 categories :

Mystery engines. These are cheap, but I don’t know what is in them and I am not sure there is enough savings in the price to justify the risk. I already did this lost – got a bad engine

Performance engines that are in the $2500 to 4000 range. It appears that these offer no savings. I could build my own for the same money and get a warrantee plus understand what is in it??

 

Thanks all - figured it out
