I have a 96 f150 and i was wondering Wat I would havta change to swap a 5.8 in place of my 5.0

 

Complete engine, computer, y pipe from same years 94-96

 

The y pipe should be the same. Like he said computer, wire harness, and engine mount I think

 

Y pipes NOT the same the 5.8 is a wider motor at the heads! And if your motor the 5.0 is an ho motor (351fireing order) then your computer will work fine

 

And engine mounts are the same

 

Thank u all 4 the help but I have 1 more question ... I have a set of gt40 heads on my 5.0 ... will they fit on a 5.8 ... ive heard they will but I'm not sure realy

 

Also being a 96 it is obdII will it be ok 2 use a computer from an obdI or do I need 2 find a obdII computer

 

The head bolt holes on the GT40 heads will need to be drilled from 7/16" to 1/2" since the head bolts on a 351 are larger.

Curious - Why are you wanting to upgrade to a larger engine? I know you're set on upgrading, but I'm a fan of a good stout 302.

 

More power! Merica!

 

Another thought: Seeing that the truck is a 96, if you wanted to continue to go the 302 route, you have some flexibility (MAF) that someone like me with a 90 wouldn't have.

If my truck had MAF, I would easily have a 350hp 302 under the hood....and that would probably be on the low side of things...24lb injectors, a good torquey camshaft such as comp cams XE258-HR14/35-512-8 or a custom cam and a set of aluminum heads (AFR165, TW170 or ST 5.0R) or ported GT40s.

I'm making a case to keep the 5.0, but for some, there's not replacement for displacement. Just trying to put some suggestions out there if your 302 is getting tired.
