engine swap carb or TBI

Ok, I know I may be wrong but I'm putting in a Ford 351w in my Cherokee. So, should I put on the cheby THI set up I have or a Holley street avenger 670 carb I found on CL? the 351w is stock.
thanks

Varying opinions, but if it was me I'd likely do an old school Ford MPFI setup.
GM TBI would be further down the list for me a new aftermarket TBI setup like a Holley Sniper would be my 2nd choice.

Nothing wrong with a good carb either, I prefer EFI though.

Personally I don't like morgified throttle body fuel injection. if it's not MPI it's just a complicated carburetor. a 600 CFM Holley would do a great job.

I vote EFI any way, shape or form but the more modern the better.
If you want to go EDIS for spark control, let me know - I have an EDIS module + pigtail I'm not using

Zorm,....

i want fuel injection too
i have several cars with new edlebrock carbs
but even they have little issues here and there

if i could pay a shop 2,000 for a modern after-market fuel injection
on my wagoneer,....
and it be reliable, without issues, i would do it in a heartbeat.

but a lot of the talk i see here sometimes about
overheating computer control modules,...
issues with cams, etc, etc, i am skeptical of having it done.

***but most of all thanx for the "cheby" spelling....
i laugh everytime i see that done, cause i can just here one of my spanish friends saying "cheby" when i read it !!!

Many GM TBI guys on here, and many newer setups like FiTech, Holley, etc.

Just do it if you want to, if you have issues they'll likely be minor.
Questions just ask...

Both of mine are TBI and have many tens of thousands of trouble free miles.
They also pass CA smog testing, are reliable as hell!
Both of mine are mostly used JY parts with some new things sprinkled in here and there.
With all the newer setups offered for low cost and utilize a wideband sensor is the reason(if I was to do it all over again today) that I suggest them.

Keep in mind folks very rarely post up success stories, but the whole world hears about any/all "problems".
Take what you read on the internet with a grain of salt...

I think Ford's MPFI is the the best EFI of the pre-2000's. It is so forgiving, tuneable, and just generally awesome. The aftermarket for them is incredible. Now, with Fox body 5.0's (and trucks, and vans, and Crown Vickies) all over the wrecking yard you can easily get pretty much anything you need to install a MAF equipped MPFI on any Windsor for cheap. Or buy a kit. IMHO, it was the 5.0HO community (along with the GM TPI and Honda ricers of the late 80's'early 90's) that brought hot rodding EFI into the mainstream. I remember when a 5.0HO in any hot rod was the thing to do.

I strongly vote for MPFI. One of the first FSJs I ever encountered was a buddies late 60's Gladiator with a 351W from a late 90's Econoline. It was EFI'ed and everything worked, including the cruise control. I was amazed because we got home from a 6.5 month deployment, went to the car lot with a pile of tools to get our cars started, and his started like he drove it there that morning. My carb'ed bug on the other hand, needed love to get going. Dry bowls, dried gaskets, etc.

Over the years I had two almost identical Ford F-250s. One 1989 with a 7.5L and one 5.8L. Both with 5 speed ZF transmissions. Neither one ever had an issue that I can recall with the EFI system or the ignition. Very reliable port EFI setups that were far more advanced than GM and Mopars TBI systems of that era. That being said the 5.8s upper intake manifold setup made working on the engine far more of a PITA. I had to pull it once to do an intake manifold gasket and then a few years later to do valve covers. I would also be surprised if that upper intake manifold cleared the hood in a stock FSJ.

Sorry if I'm offending anyone here, but IMHO the 5.8 EFI was an absolute TURD of an engine. The 7.5L just completely blew it out of the water in every way and was sooo much more reliable and easier to work on. It also got about the same gas mileage (Maybe 0.5 MPG worse). And that 7.5L truck had a supercab and 4.10 gears as opposed to a single cab with 3.55 in the 5.8. My buddy has an 85 F-150 with a 5.0 EFI (First year of EFI for Ford Trucks) which is also a TURD, but no issues with the EFI system .

Now if you are talking about a pre EFI 351 from the 70s or early 80s, you might be okay, but it's still a lot of fabrication involved to make it work with pretty much no benefit over an AMC V8. AMC engines are not exactly the greatest engines out there, but there is no way in hell I'd put any effort into adapting a FSJ to fit a small block Ford.

Sorry if I came off like an angry old man with that last post. I am not an angry person, nor old . I just get flashbacks from working on Fords for so many years.

If you dont want to just stick with a 360 and something like a holley sniper efi or a good carb then a chevy ls is your best bet. So much aftermarket support for things like engine mounts and tranny adapters.
