351 in a T-Bird?

April 06, 2009, 08:39:23 PM

Alright so the previous sale of our caravan with the bad trans fell through.
I've now been offered a 351 out of a 1992 Bronco for the van.

What do you guys think?

Would this even work in an 84 T-Bird? (Upgrading from a 3.8).

Or should i just hold out for a 302 like planned?

If it fits, I say go for it:burnout: May have to change upper/lower intakes though

there are very few good intake choices unless you go with a carb style fuel injection. Unless you want to go carb, I would stick to a 5.0.

Going carbed would make the swap a lot easier though...

Less power with a carb right?
Dont forget~I have a 3.8 currently lol

As long as it can be upgraded at any time in the future, Im fine with that.

You can buy 351 swap kits, and I'm not sure about the carb giving less power, someone more knowledgeable on that subject could tell you more

The 87 5.8 w/ 4bbl actually has the same power as the mpfi versions (Except for the 92 and 93?)

Carbs make the same power as F.I. I converted my 84 T-Bird w/CFI 302 to carb. I used the same throttle cable. I just had to make the 40 lb. F.I. pump to deliver 6 lbs of pressure at the carb. I bought some brass pieces at the hardware store. See pics below...

The fuel comes from the 40 psi in-tank pump ,(I put a 88 Turbo Coupe gas tank on the '84) shoots across the "T" brass block and then returned to the tank. The smaller return line creates the perfect restiction to produce 6.5 lbs of fuel pressure at the carb.

Note: Ignore the arrow on the top of the block. The fuel comes from the tank into the top and shoots across the block then makes a 180 degree turn and back to the pump.

I used a Duraspark distributer and then wired up a GM H.E.I. 4 pin module that works with the stock F.I. coil.

Full of shiznit...

Guess you didn't read what I posted in the 5.8 conversion thread(way down there, all of two threads)... Basically if you'll be chasing a dozen or more small items, especially if you try to stick with EFI... Most of the others are saying "yeah go for it", but no doubt several ain't got a clue what's involved... I wouldn't recommend it if you don't have a cheap source for the parts needed, or have a good idea how to rewire it, especially if you go with EFI

If you already have a 5.0 in the car a 351 is a direct bolt in(otherwise you're going to need motor mounts with the 3.8 or 2.3)... This is assuming you have a double sump pan already on the larger engine, as the 5.0 pan will not fit a 5.8... The exhaust(headers) and engine brackets are different due to the 5.8 being taller... I believe the 5.0 alternator bracket can be used, but the P/S-A/C bracket is different...Also will need to verify which rotation water pump it uses, the Fox bodied cars all use a reverse rotation pump, at least from '86-up... You'll need 351 swap headers and Stang 5.0 H pipe with a full dual system, if you expect to get any power out of it...

Intake is the big issue, except for the '93-'95 Lightning setup(and it's very close), no stock truck intake will fit under the Bird/Coug hood... Doesn't really matter, the 5.8 truck intake is a POS(again Lightning excepted) for making power past 4000 RPM.... Depending on engine components, you'll likely need a Mass Air 5.0 EEC... Assuming a stockish 5.8, I suppose you could use a MAF truck EEC from '94-'96, but like a 5.0 MAF EEC, there will be modifications necessary to your original wiring harness...

With the 5.8L Conversion Is there a 5.8L EFI that will be a direct fit...

Did you read the first post before yours?

As far as a '97 F-150 with a Cleveland motor...lol, they ain't made Clevelands since well before I was born, and I'm over 30.

As far as 351 engines, none were ever offered in a '97 anyway, except for F250/F350, and most buyers then opted for either the diesel, or the 460...

Absolutely NO 351 of any bred is a true "drop in" ordeal...
If you go efi, be prepared to spend easily over a grand.
Carb is cheaper, but I have yet to see or hear of any carb motor making power equal to an efi set up, while maintaing the streetability, and cold weather performance..etc.

Prove me otherwise if you feel I'm wrong. (I also don't mean full on race cars, because we don't (usually) drive said race cars on the street..) lol

Well I really would prefer to keep the car efi If at all possible....but I want the High Output... Would the Intake off a 5.0 HO work?
