Default EFI + 351w??

I have read up on the EFI swap for the 302 and that seems pretty easy.. But does the same thing apply to the 351? Can I just find an intake and computer from a 351/5.8l truck and bolt her up. I think that could be an interesting swap.. Maybe a little more fuel effecient.

I know the deck height changes with the newer blocks.. Would that make a difference in finding an intake that will seal up correctly?

Any suggestions?

i think you could, but IMO, stock type fuel injection looks very out of place in a classic. i would go with a aftermarket type if you are going fuel injection at all. JMHO stay carbed

I've always thought about fuel injecting mine too... but that involves a lot of work I think, such as relocating the battery and such

Checkout this EFI link:
www.affordable-fuel-injection.com

They have a complete throttle-body injection kit for about $1300. The TB unit just bolts onto your intake where your carb was. Use a standard air cleaner housing so it still looks classic and no need to move your battery.

My 4.3L Chev Blazer had an TB-EFI similar to this. It looks just like a carb until you look down it's throat and see the injectors. Worked quite well too.

Have you used this?

Or anyone know of someone that has used this?

actually, Gothand has a 351 that he swapped efi on recently. PM him if he doesn't see this thread, not sure if he used a kit or anything.

the only 351w efi's were truck,van and lightning and cobra, the truck/van are very tall and speed density so cams,cyl heads are a problem, the lightning and cobra used gt 40 style intakes and fit bette AND are mass air type like the later 5.0's.

hood clearance might be tight with a oem efi set up.

Actually, I pulled the 351W when I redid the car and swapped in a Ford Racing 5.0L motor. That said, there have been PLENTY of 351W swaps into '87 - '93 Mustangs that it wouldn't be too difficult ... though not cheap. The only way to do an EFI swap cheaply is to use stock take-off parts. Once you start buying aftermarket manifolds, TB's, MAF's, high flow injectors, etc., the price starts getting up ther.

That said, I love having the EFI in my '65. Although I don't mind how it looks under the hood, I rarely have the hood open unless I'm performing maintenance.
