Ready to rebuild my 351 windsor, it is a 95' Want more power! Would like to stay efi, so that in mind which head intake, cam, piston, and any other upgrades do you guys suggest? Going to be used for hauling and playing in snow mud ect.ect.
my engine currently blows oil about 2 qts every front tank fill up its horrible so my plan is to find a good running 5.8 and tear it down and add all the fancy upgrades.i have access to tools and shops and i have a special *truck fund* to help pay for this(truck fund = left over quarters from a year of shooting pool LOL)
hopefully i can get pictures up of the build and im hoping to gain some help and much needed knowledge from fellow members when i tear into this project so brands,websites, of needed parts would be greatly appreciated thread will be staring in 2 weeks so ive got that much time to gather the items needed
i plan on running 33'sx12.5 which is what i have on their now and probably not helping my already oil guzzling motor
trans is a e4od wheel base is 168.4'' 1995 f-350 crew cab ext. bed
i want this truck to be a nasty mthr trucker able to pull a load and tear through snow and mud and to sound super nice
time my truck lives up to the vanity tag and not to the amount of exhaust it blows through the car driving behind me :P
im very good and tearing things apart and putting them back together but aren't we all

 

About the only upgrade you should do is a set of GT40 heads (iron) and a set of 1.7 full roller rockers. You've got a roller cam block, if it's got the roller cam, stick with it, it's perfectly matched to your truck. If you REALLY want what I think you want, you should consider a swap to a 460. Or stroke the 351 roller block, and add a little larger roller cam and Iron GT40 heads. Any F350 is really too much truck for a 351. It should at least have a 7.3 diesel.

 

I WENT AND LOOKED AT ONE THE OTHER DAY GUYS WOULDNT BUDGE OFF OF HIS ASKIG PRIVE EVEN THOUGH IT WAS LEAKING OUL OUT OF THE REAR MAIN SIGH
I do know where their is a wrecked f350 duelly been sitting for years i think it has under 30k miles on it it is a 97 but its been sitting for a very long time but.... to convert my gaser into a power stroke would not be worth the task or is it ?

 

Judging by your intended use of the 351, it would at least be worth swapping to a 460. Your oil consumption now is likely a direct result of the 351 trying to push that 8000 lb truck. Putting in another will simply give you more of the same. At least build a 351 based stroker, with no higher than a 9 to 1 comp ratio, and top it with a mild set of heads and an RV cam, that will at least buy it a little more time.

 

will the current trans work just swap bell housing and what would need done to drop a 460 in it and mileage is a factor i get 6-7 mph right now was cruising forums and someone had said their ecm was bad making it run rich and blowing smoke ? i love this truck took forever to find one oddly enough the ones i did find were only 2 wheel drive and powerstrokes still go for insane amounts of money and i just dont know how feasable dropping a 7.3 in my tuck actually is

 

That's the only snag about swapping engines, you'll need to swap transmisions too. Your best bet is to build a low compression stroker motor. Your mileage will stay about the same with a 460. It just won't be in a bind all the time trying to push that heavy truck. If you build the stroker right, you'll take some of the stress off the engine, possibly improving the mileage some, but don't get your hopes up. The same truck with a diesel will get nearly double the mileage you get now. Just food for thought. My 99 SD F250 gets 19-22 mpg at 70-80 mph. I paid $5000 for it two years ago. It had 258,000 on the odometer then. They're out there, you just have to look for the deals. Only drawback to a diesel now is the cost of parts and the difference in fuel cost. They will pull anything you hook behind it though, or at least the ones with the manual transmissions will (mine's a 6 speed)

 

Full rebuild on a 351, balance rotating assembly, lightly massaged GT40 heads, good RV roller cam, headers. Don't write off the 351, just spend time in the right places of the build. I'll post up specific parts when I'm on a pc n not my phone.

 

351 cubic inches isn't nearly enough for what is surely a 7000lb truck, you need more displacement regardless if it's gas or diesel. A "mild" 408 stroker with aftermarket heads, cam, and intake will make big block torque and potentially close to twice the horsepower the stock motor did without requiring a complete powertrain swap, but you will need to get MAF and add a tuner or use an aftermarket EFI system and also deal with that E4OD.. which also needs a computer brain to operate, so this isn't a simple or cheap adventure. You could blow $5000 easy so searching for a newer PSD truck instead makes a lot of sense.

 

My 99 F250 weighs more than 7000 pounds. A crew cab F350 dually will weigh in at least 8500.

 

Crew Cab dually 4x4s weren't made in this body style. He didn't mention it being a dually anyways.

I completely disagree that a 351 is too small, it's all in the setup when you're putting it together. Stock, I'll be the first to admit they suck, even a 460 doesn't live up to it's Big Block power potential in stock form. Get the thing balanced, select a nice Lunati cam for idle-5000 rpm performance, GT40 heads, cleaned up and massaged a little, headers. The factory setup is for emissions, which they weren't all that great, and the parts listed really wake up engine, while getting rid of the bottlenecks.

Throw some 4.10s in the axles, it'll move along decent, and still get better mpg than a 460 with 3.55s.

 

I agree with you 100% on this.. there is a lot of untapped potential in an all stock 351, but that's a long way from being the "tow anything you can strap behind it/stoplight drag race monster" that the OP said he was looking for in the original post, that's only possible with cubic dollars when you're dealing with a vehicle this big.

 

They weren't ? Gee that funny, I've seen dozens like it around here. Dually or not, it still will weigh in more than 7000 pounds. And the 351 he puts together will self destruct in little time from the way he intends on using it. It needs an engine with more torque than a 351 will supply, otherwise, he'll be running around with his foot in the throttle body constantly, just like he is now.

 

my truck weighs in @ 6780 with no one in it..... my rear as ive been told is the same one used in dual wheels...i know their has to be away to get the power the 351 is intended for its stock so i know its tuned down to meet government requirements..
but back to my other question how feasable is it to make mine a Powerstroke? if upgrading my 351 isnt feasible ?
i have some pictures of the kind of work i do... ill post them in a second..

 

Cab and chassis, yes. Pickups, no.

Everyone has dreams of what they want for a motor build, and what they want it to do when complete. Very few actually know what the capabilities are of the platform they have. Also, they seem to think that the stock setup is an indicator of what it's going to be like always, which is wrong.

I'm talking from experience that a 351 can indeed do a good job in a truck like this, when built properly. Torque? Gear it a little lower than you would a 460. The 351 isn't going to mind a few more revs at all. He's not running huge tires, he's not driving around a 10k lb truck, and he's not towing 30k lbs on a regular basis.

With the way you guys are assuming stuff here, he's not going to be happy with a mildly leaned on 460 either. A pretty well built diesel is about the only thing that would move a truck out like everyone is describing. I personally think if he's stuck it out this long and even contemplated rebuilding the 351, a well selected setup and build would suit him just fine. Just my opinion, but there's lots of those already floating around in this thread.

 

Engine, trans, computer, associated wiring harness and fuel system are the major items. The rest of the drivetrain will support it, so that can stay as is. Finding all the components in good condition, with lower miles, will be the hardest part, unless you plan on rebuilding a PSD and associated tranny before installing them.

I'm not against the swap at all, but I don't feel the 351 is as bad as everyone else in this thread.
