i was thinking about swapping my 302 to a 351 and swapping my trans from a E40D(auto) to a AOD(man). with as least as possible computer controlled. how hard do yall think this would be?


i have a 92' F-150

 

Well the engine swap is a positive but the trans swap is a negative. The aod is a weak replacement for the E4OD and the E4OD is more common with the 5.8 so finding a computer and wiring for it would be easier. If you are determined to do this, I would suggest getting an engine and trans from an 87-89 truck as you will be back dating your truck to get the product you are wanting. I think it would be easier to purchase an older version of what you want than tring to do this swap.

 

if i got the 92' 351 and kept my E4OD how hard would it be to reprogram the computer?

 

Ford changed the e40d I think in 94 sometime. They made some improvements that made it a lot better.You could either try to find one of those or have yours rebuilt to those specifications.

 

ok, but how would i reprogram my coputer to compinsate with the 351?

 

I'm pretty sure the computer thats running your 5.o/E4OD now, will run your 351/E4OD.

 

Is your 302 an HO or not? Some of the 302 (non HO motors) used a different firing order than the 351W. HO 302's had the 351W firing order.

 

what is HO and how can find out if it is or not?

 

The HO (high output) 302's only came in cars (mustang, T-Bird ect...), your 302 is not an HO. The 302 computer will run the 351 but it will run in an unsafe lean condition. The computer doesn't care what the firing order is since it is a batch fire system. Find a 351 computer, go to www.fordfuelinjection.com and click on ECC program codes to get the # for the ecm you need to find.

Let us know how it goes.
