351w vs. 5.8L
I am new to Ford trucks or even Fords in general. I have a question that may seem dumb....here goes. I know that a 5.8L is a 351 as far as cubic inches and I know that my 351w is carbuerated and the 5.8 is fuel injected. I drive a 1995 F350 w/ the 5.8L with high miles. The 351w was built for a project truck and still sitting in the garage. I want to know if I can put the 351w shortblock in the place of the 5.8L. You know and just put the heads and intake and injectors back on the 351w off the 5.8 L. I tried a similar swap on a chevy vortec using an older shortblock and a couple sensors didnt have bosses to screw into and such. Any help with this will be very appreciated. thanx.

Technically the 351 has been refered to as the 5.8L by ford since the late 70s.
You will have to have the 95's timing chain cover for the reverse flow water pump in serpentine belt systems. You will want the heads, but the difference b/w ford and GM is that ford kept most all the sensors on the intake for the 351. I do not believe ford offered the 5.8 with distributorless ignition as it did with the 302, so the short block is the same one used by ford since the late 60's.

Yes the older shortblock or even longblock will bolt right in, but you'll have to change the cam to something computer friendly, it's not likely the cam in there now is compatable.
Swapping on a Carb is not going to be cheaper or easier either, because as with most of these trucks the tranny is also computer controlled so the computer has to stay or you have to swap in a different tranny.

Reason I added it was because of the crankshaft position sensor. I didnt know if it was a pick up in the psuedo-distributor or in the timing chain cover.
