I have a 95 Ford F250. Two pistons are bad I found a block with pistons and crank installed for a really resonable price that only has 68000 on it. The engine in my truck is a 95, but wondering if my heads will both on and will it work with my 95 5.8 351?

 

yea it will work.... what size is the block? the 289 302 and 351w all use the same head bolt patterns

 

Not really sure what your asking about . You have a 95 F 250 with a bad motor , one of the motors is a 95 351 , what motor was in the truck & what motor are you replacing it with ?? Year & size ?? The 95 should be a roller motor . The difference between the 302 heads & 351 heads is the head bolt size . The 351 has bigger head bolts than the 302 , but both will work , so if you put 302 heads on a 351 they need to be drilled for bigger head bolts...Lew

 

Currently my truck has a 351 5.8 litre. I am replacing with a 90' 5.8 block 351. It should work right?

 

Your heads will bolt right on no problem , if the 95 has a roller cam & the 90 is a roller ready block you should be fine ....Lew

 

'90 5.8 block is not roller ready so you're stuck with a flat tappet cam unless you buy linkbar roller lifters.

 

If the 90 block is not roller ready will my heads still bolt up and work OK or would I need to change cam and lifters?

 

The heads are fine , like conanski said the 90 block is not roller ready , so you will need to change cams unless you use a roller block . So thats up to you ..Lew

 

Thanks for all the help

 

One last question. The guy with the shortblock is interested in selling the whole engine for 100 more. I check a couple sources and they said it would work as long as I use my Intake Manifold (mine has air going right into intake and not head). The only other differences would be that I would have to use a different rear main seal, hole for knock sensor would need to be tapped out, and my accessories.

Just wanted to check to get one more opinion before I bought it.

Thanks,
