I know this is meant for modular engine questions but thought I would ask anyways. What year(s) truck/broncos have the 351W EFI, EFI being important, stock. Some places say one year some say others. Have not found info online that match. What year and what model if you know.

 

1987-1996, I'm not sure if there was a 1997 Bronco, even though the f-250 and up changed style in 1998. I'm pretty sure 1986 was carbed, not EFI.

 

The 5.8L went EFI in '88, and it was used in 1/2-tons until '96 (when it became OBD-II). Heavier trucks used it a few more years, but I'm not sure if the heavy 5.8Ls were OBD-II.

FYI
The 5.0L went EFI (optionally) in late '84/'85. All 5.0Ls & 4.9Ls went EFI in '87. 5.0Ls used in Explorers/Mountaineers are distributorless. Some '94-95 engines are MAF; all '96s are MAF OBD-II.

 

Ok thanks. Trying to find one for my 1990 F-150 to replace my I-6. The local auto salvage yard just says 19XX Ford truck/Bronco/Van and then you have to match date to find what engine and what model you want. I think this makes sense.

 

Unless you're trying to turn MONSTER tires, there's really no advantage to a 5.8L. The 5.0L puts out ALMOST as much power & torque, but it's a much lighter engine, so it generally performs better. It's also more economical, especially if you get a distributorless one and wire it up so it runs stock.

But there's nothing wrong with the 4.9L. Mine pushes my heavy Bronco just fine - I can get a speeding ticket anywhere in the country (and I HAVE); it'll tow over 10,000 lbs, and it does great off-road. Most people THINK I have a V8.

The key to maximizing performance is just GOOD regular maintenance. Keep everything working the way the factory built it to, and it'll last forever. Mine has somewhere near 400Kmi on it, and it's more reliable than many new vehicles. Runs cleaner, too.

 

Ya I know the 302 is just as good but I like to be different. Have a stroker I6 in our 88 Wrangler, have a stroker in my 03 Cobra, and now with 200K+ on my 1990 F150 I6, I would like to put a V8 in it. I have always wanted a 351W and I will be doing head and intake port and polish and add a small cam. Just for something fun to play with.

Also someone said the Bronco is IIRC. For the life of me I can not remember what that means.

 

Huh? Said the Bronco is what? Can't remember what "IIRC" means? If I Remember Correctly

A 5.8L won't be "different" - it was a stock option from the 70s up to the late 90s.

 

Ya I had one of my Blonde moments. I am use to mustangs and IMRC (Intake Manifold Runner Control). Hit me later on that IIRC meant what you said.

I am going this weekend to look at 3 Broncos 1 Dually and 4 Vans. All 88-96. I appreciate the help and hopefully one of the Broncos will have something good.

 

There's a lifted '94 C350 for $5K on FSB right now in the "all other" for sale forum.

 

The 97-2001 Explorer 5L motors are cammed to pull pretty well.
It takes some changing around to use in an earlier application but is doable.
I am doing this right now for a 90 application.
These motors are cheap in the yards because of very little call for them.
They have the hi-po 40p heads and good intakes.
Need to use the early pan, oil pick-up, dist, front cover, water pump etc. to dress them correct.

 

Either the 302 or 351 will be hard on fuel. Personally if I had both available I would pick the 351, it is hard to argue with 1/2" more stroke.
