Hi everyone,
I'm wanting to put a new engine in my 1988 Ford F250 that has a 460 7.5L engine it in. I do a lot of traveling over Snoqualmie Pass and I drive horses trailers a lot. So I was looking into a newer year engine that would have a little more power but that gets me better gas mileage then the engine I have now. So I'm wonder if I could but in like a 1990's F350 engine into my 1988 f250 and will it be compatible with all the wiring and harness.

and wanting to get other people's opinion on if I should put the f350 460 in or just put a new f250 460 engine into my truck.

Thank you.

 

No difference between F-250 and F-350 engines.

There will be wiring differences between some years, but I don't know details on that. Also some changes in the heads / intakes (but that might be only carb vs EFI and I'd guess your '88 is new enough to have EFI)

 

I'm knee deep in my first 460 build. I came across something recently that might interest you. I'm swapping an '89 for a '90. I didn't think there would be any differences because they are the same generation f series. the fuel rails on my '89 connect up by cylinder 1 where as the '90's fuel rail connects back above the bell housing. Not incredibly important but there are some differences even between one year.

 

It's not a chebby. That's cylinder 5.

 

my bad you're right. I meant 5.
