The eec is the computer, need a 351 computer for a 351 efi engine. Yes some have said they kept the 302 eec and it worked fine but I wouldn't trust it in the long run especially on a speed density system. With the wrong eec you won't be putting in enough fuel so it will be running lean, which is not good(i.e. bad). Need a different timing chain cover because you're talking about a carb'd engine which uses a diff style timing chain cover so the accessory brackets and water pump won't bolt up like they're supposed to if you want to keep the serpentine belt, which you should. This is probably also what Kem was talking about with the accessory brackets.

 

I believe the serpentine belt set ups use a reverse rotation water pump and this could be the reason why and different timing cover is needed. I am not 100% sure on this but I recall something about the pumps being revers rotation.

 

The windsor I am using already has all the belts and pulleys installed. Does this mean that I won't NEED to change the timing cover?

I have the upper and lower manifolds, the new distributor, new oil pan and pick-up. Aside from the eec and new cam is there anything else I am going to have to buy to get this thing running?

 

If you are going to use everything that is already on the 351W then you will be fine.

 

are you gonna make your 351 efi now? if so then you will need to use the acessorys off of your 302 and replace the timing cover/water pump on the 351w with one from an efi 5.8.

 

Why do I need the accessories of off the 302? The only thing that the windsor is missing is the a/c pump and brackets, and they are no use once the top is off.

 

the 302 uses the serpentine belt setup. your 351w does not. if your going to go efi on your 351w you need to change the front timing cover and get a reverse rotation water pump to use the serpentine belt system. then use the brackets from your 302 onto the 351w.

 

but why do I need to run the serpentine belt setup? Are my chrome pulleys not good enough for efi?

 

i dont think you can run the different front timing cover and a regular water pump. that is why. does your 302 have serpetine belt or all the fufu chrome pulleys? hehe

 

I prefer to call them 'old school chrome pulleys'.
The windsor is complete, including water pump, alt and powersteering. It never needed anything to run, just a new home.

 

right but its carb and your bronco is setup for efi. so i guess i havent heard you say which way your going

 

Ah. I am going to swap all the efi off of the 302 and onto the 351. I think I have everything now, aside from the cam. I was out to look at the bronco today (it's not at home yet) and it is running seperate belts (not serpentine), so I am assuming that the cover will be the same anyhow. The windsor is running a 'LeMans' cam in it right now. My dad has no idea what the specs are on it now, it has been far too long since he last thought about it. I wonder if a performance carb cam, will work in there. probably not.

 

the upper/lower intake from your 302 will not fit on your 351w. you know that right.
if the 302 is running seperate belts then your all good there. as for the cam it needs a lob seperation of 114* so a compcam 35-255-5 is a great upgraded cam.

good luck and have fun
