which powerplant?

[CDW6212R]

The Mustang convertible and Mark VII engine mounts have been the strongest to use for a long time. Go by what the conversion swap threads suggest, they should be the best information.

the L&L mounts look odd because they are an aftermarket product designed to place the 302 enging into a Ranger/BII/Gen I Ex engine cradle.
They are also a solid engine mount, no rubber no urethane, just metal and bolts.

Going from 3.73 to 4.10 should not be an option, I made this mistake with my Bronco II, after spending $$$$$$ to re-gear from 3.7 to 4.1 I wish I would have gone 4.56

I have 33" tires on my 96 Explorer 5.0L with 3.73 gears and it works great, especially on the highway

keep your 3.73 with the 5.0L, worry about gearing down the road if you think its still needed

jamie, do you have any regrets about going the solidmount route. I have been considering this.

Think they would be tolerable in a street only truck.

I think I will most likely end up going with rubber mounts and fabricate my own custom torque limiter.

 

[seth247]

Heeeelo

 

[seth247]

I've decided on a 331 crank.

I don't want to be a victim of the 'how long will a 347 last' debate and 331 cubes is plent for my application. Add in an eaton m90 and I'm happy.

My advance adapters conversion manual came in the mail yesterday and I finally understand how the mounts are going to be positioned and what I need to look for.

If your considering the swap. I definetley(how the he'll do you spell that anyway?) recomend the as book.

It's under 20$ and it has all you need to know to wrap your head around this thing. I also have the MRE manual but it is not as complete in some areas.

 

[seth247]

Ppppppppppppppppppppppppim bored.

Hey don how's the 347 coming along?


Uh oh. It's my 666th post. That's not good.

 

[seth247]

oh hey. I forgot. I've got the Vortech maf howsing for sale if anyones interested. I only recomend it if you can tune the vehicle to match after installing.

the solid mounts in my BII are perfect for me
Also my 5.0L in the BII is mostly stock, aside from the TM headers, intake and exhaust its a stock 98 GT-40p so it idles SMOOTH as can be.

in fact when I drive my Explorer (96 5.0L with E cam) and then drive the BII I often wonder if the BII is even running when I come to a light.

The solid mounts do NOT bother me one bit for daily driving, it does help that I have urethane body mounts and a very very soft suspension
Overall the Bronco II feels 10x more solid then it ever did from the factory
\I think the factory rubber mounts allow WAY TOO MUCH movement in the drivetrain to begin with

I would:
solid mount an off road truck or drag truck or non daily driver truck
urethane mount a daily driver, tow rig, grocery getter,

but anything is better then the weakish crappy stock metal glued to rubber factory mounts

If you do an engine swap, the EPA will come after you and hunt you down

lol, jk

 

[seth247]

yeah. If they could keep up with me in their prius'!

 

[seth247]

Though I'll be retaining all the emisions equipment so they shouldn't have anything to ***** about

 

[410Fortune]

when you drop a 98 engine into a 92 truck emissions is not a concern as long as you retain all the original 92 emissions equipment (IN CA you have to use all the 98 emissions equipment)

The conversion in my Bronco II is 100% emissions legal in all 50 states (because it will pass in CA)

The 98 5.0L I run blows LOWER NUMBERS then the original 88 2.9L did, even with 2 additional cylinders.

If we were talking about removing a 92 engine (DIS, MAS, EFI) and converting back to a speed density (distributor, non mas) or even carbed then you would have an issue potentially.

the 98 OBD-2 emissions and electronics provide a MUCH MORE efficient engine then the original 88 powerplant = emissions nazi's happy

The only problem I have passing emissions is they will not test a vehicle with 35" tires I have to bolt on 33's every 2 years to get emissions. I cannot WAIT until my 88 is considered a classic, then no more emissions for me and the sky is the limit!

I've paid the balance of my 347 engine, and arranged shipping. I have a lot of things left to do, such as an air cleaner, e-fan, making trans lines(rust), finishing the 4WD, and having the radiator cleaned. I have almost all of the bolts I need, and I don't yet know if the stock 98 manifolds will work well with Canfield heads.

Jamie, where did the urethane body mounts come from, and are they any shorter than stock? My 99 truck mounts were like new, but my 98 came from Milwaukee, it would be tough to do I'm sure. Regards,

 

[410Fortune]

my mounts came from James Duff, but this is a 88 Bronco II so its a bit different.

yes they are MUCH shorter then the factory rubber mounts, especially after 290K HARD miles, my stock mounts were broken, stretched, and rusted.

I lost 1/2" of body clearance with the all new urethane body mounts which made things VERY TIGHT for the BII with no body lift and a 98 5.0L drivetrain, however it feels like a totally different truck on and off the road, much much mopre solid and stable, especially in the twisty stuff off road

I believe energy suspension / performance accessories makes a urethane replacement kit for the Gen II Explorer?

My Engine mounts are L&L solid and my trans mount is a AutoFab 4.0L A4LD unit custom modified for my bii/4r70w/AA adapter/1354 setup

 

[CDW6212R]

There weren't any 2nd gen. choices when I looked in 2004 or so, and I'd like to consider that if they can be had. How did you make the swap, how high did the body have to be lifted to swap them? I did mine with the body off, so never considered doing it with everything connected. I'd like a better trans mount still, but I bought a new Ford part. Did you come up with something that is better than the stock mount?

 

[410Fortune]

stock mount = SUCKS
You can easily replace them with the body in place, because they are shorter then stock so the body will actually drop, they slide right in place.

It went fairly smooth when I did my BII, I did two mounts a day because it takes 45 minutes to cut through the stock mounts with a sawzall (cab mounts are solid metal sleeve through frame, have to cut through sleeve even if bolt removed = pita)

I also had to drop my gas tank to finish the 4 rear cargo area mounts, so all in all it took me a week and 10 sawzall blades, of course if they did not have 290K miles on them it might have been 10x easier.


trans mount:

and you can see the new blue urethane body mounts:

 

[CDW6212R]

Thanks for the pictures, it looks great, I'll consider that for later on.

 

[seth247]

cool I want tobreplace my body mounts when I do the body lift to make room for the drivetrain. I'll see if energy has any for first gens

 

[CDW6212R]

FYI, the body mounts are the same for 91-01 Explorers, my 93 body mounts were the same as my 99 body mounts.

 

[seth247]

ah, ok. I found some from superlift but they were, predictably, rediculously overpriced.

I'll keep looking.

On the engine mounts I was thinkin, I'll do the polyuerathane mounts and do an engine to frame torque limiter. So I could take it off for road trips or the girlfriends who don't like a rough ride... well not in the truck anyway.
