5.8L differences F150, F250, E series ?

[Timmy390]

I've read the F250 and E series are lower compression. Is that the only difference? How is that lower compression accomplished? Different pistons?

I found a 96 E350 van with a good 5.8L. The van is running and driving but it's beat up so no real value. Dude is asking $850 for the whole thing.

Anyone know if the front dress will fit in the Bronco?

I am working on a roller 351 from a 96 bronco, and I have a co-worker that is helping me address these issues with mine. So far he has narrowed it down to pistons and gasket thicknesses to reach the ideal quench height for the chamber. Im sure there is more but we havent gotten deep enough into it yet. I believe I will be going with the Keith Black flat tops with valve reliefs to adjust compression. As far as front dress, I am using most of my 302 stuff to keep it simple and affordable, or at least thats the plan! HTH

 

[Timmy390]

I was hoping it was only gasket thickness.

I can't find much info on the 96 E series 351W's
I found this but don't now that it's correct.
HP 210
Torque 310
Bore 4.00
Stroke 3.50
Compression 8.8:1

Compression is directly related to head volume, piston type, block deck height and gasket thickness. The style of piston and the head volume typically make the biggest changes in compression. Some engines have dished pistons, some flat top and other domed (ex. high compression race engines). When you look at heads, they vary widely 50-70ccs and all of this changes with head machining as well as block machining.

Understand but looking for specifics on the E series and HD series motors if I can get it. If it's just heads and gaskets then I'm all good as I can get a set easy. If it's pistons then it ups the difficulty scale.

Trying to figure out if it's worth my wild to get the E350 or not.

This looks correct. 8.8:1 with 65 cc heads. The pistons are hyperutectic with metric rings. They have about a 18 cc dish. Pin height is different than pre-94 351w pistons. Rod length is probably different also.

Thanks Viperwolf1

So a set of GT-40p heads with 58-61cc chamber volume should boost the compression up a bit closer to what the F-150 motors have.

No issues with running the P heads on the HD series motors?

At one time the F150 and Bronco were 8.8:1 compression and F250/350 were 8.3:1 compression. But I have also seen a lot that shows them all at 8.8:1 compression, especially in the later 90s.

P series GT40's will work on any small block 302-351, only issue is the exhaust with the angled plugs.

59cc should get you right around 9.2:1. You might have to drill out the head bolt holes and then there's the spark plug clearance issues with the GT40P's.

Stock manifolds for the P heads work on the Bronco Yes?

Yes they will need to be drilled. The clearance issues are with the exhaust and plug wire boots right? Not inside the chamber?

I have heard of a few folks using the stock exhaust manifolds after some minor grinding.

Right. No problems inside.

 

[Timmy390]

Thanks for all the info guys

Well it sounds like I need to just go offer the dude $500 for the van, strip what I need, try and sell the trans and a few other parts and take the rest to the crusher. Heck I might make money....

Looked at the van today. Motor is good with the exception of a leaky oil pan gasket. The digital odometer isn't working so don't know the mileage but figure just on the age it's got 100K plus on it. Starts right up no knocks or pings. Rev's freely and all the accessories on the motor work.

Dude will not take less than $825. My guess is it weighs 5K plus pounds so removing the motor and trans should put me about 4K. Going to see how much that will bring me at the crusher. Not sure what the going rate is.....maybe 10 cents a pound?

Are E4OD's worth anything?

The 96 351W has OBDII and has some unique parts. Are you staying fuel injection? It will have a roller cam. It will also have a Saginaw steering pump, a good thing!
The front dress is tight in the early Bronco but will fit according to others. It's the same length as 87-93 Mustang 5.0. It will have a 3G alternator probably a 90 amp another good thing.

Scrap varies by area, you will have to call local ones. It's about $6 for a hundred pounds for a car around here right now.

If the transmission works good try to sell it before you remove it so they can test drive it and tell them no returns!

$6 per 100 gets me $240. I would sure like to be in the 3-$400 range. Still at $6 that puts me in this thing $585 I don't think that's too bad for a running roller 351w with all the front dress. I'll be calling around on Monday for sure.

Good call on the trans. I didn't think about that.

Yeah, ODBII's first year as I recall. Going to go EFI at some point. Considering the TBI setups that bolt onto a dual plane intake but will go carb first. Thinking of running a ProComp HEI distributor. I hear good thing and bad. I hear the same about MSD stuff but I've never had any issues with my MSD setup on my Mach 1.

I'm counting on the front dress fitting and getting the benefits of the serp setup and the upgraded alt and PS pump.

Since it's a E350 it might be a bit more than 5000 pounds stock. Cargo van or passenger? 138" wheelbase or longer?

Passenger 138 with the seats removed and some interior panels missing. Think the door sticker said 5400 and change.....so 4K pounds with motor and tranny removed might be slightly on the low side. 4500 plus is what I'm hoping it weighs out to be.
