351w swap

[likeshills08]

So, earlier today I purchased a 1989 fullsize bronco for 400a bucks. Has a 351w and c6. My ranger is a 93 reg cabtill shortbed 3.0l with a m5od, 3.73s on 37s... obviously underpowered. Figured this bronco would be a perfect donor vehicle. So Ive read thru the v8 swap tech article several times and also the james duff reccomendation v8 swap page and there is sparce information on the actual 351w swap. I plan to swap the entire drivetrain and ecm harness and splice it to the ranger body harness. I am just trying to figure out what parts are swap in bolton and what i absolutely need to modify. The engine mounts are a gimme.

However i have yet to find a set of headers that will work.
If the deck height is taller will the advance adapter shorty headers work for a 4wd? I read thru the header sticky and all i saw was the uses of headers on 302s. None for 351s.

Also i also noticed there was little information on the fullsize transmissions and t-cases. Figuring that since the broncos wheelbase is close to that of a ranger then length is not a problem. However width is a question. Does the t-case from the fullsize truck interfere with the d-side frame rail?

Does the 4.0l radiator sufficiently cool a 5.8? A c6 or e4od?

These are just a few things off the top of my head that slightly bothered me. Im just trying to figure out what has worked specifically in a 351w swap. Thanks

Thanks guys!
Drew

Search around through here it has been covered a lot recently. Whatever mounts work for a 302 will work for a 351. Suggestion, make adapters for the 2.9/4.0L mounts. They aren't hard to make and give opportunity for better engine placement, lower is better. You will not find a set of headers. You can get a set of 302 swap ones but you will be cutting them up to make them fit. There are manifolds that fit from some 70s cars. That should have a BW1356 t-case; I usually advise against them because of size but some have been using them recently. You'll likely have to make a small notch in the fame to use it. The older/stonger NP205 fit with not frame cutting, the Np208 is a little bigger and fits as well with some cutting of tabs on the t-case. Most all fullsize trucks use the same bolt pattern and spline for the t-case. A 4.0 rad won't be big enough.

Yeah i saw the v6 conversion mounts. What about the james duff motor mounts?( apparently they pick the engine up a little higher then stock). Why would it be better to have the engine sit lower in the frame? Wouldnt that make less space in between the frame rail and head, in turn giving less room to play with for headers? I have a 3inch inch body lift so im not worried too much about body problems besides of course the heater box. Every thing else i can handle with a sawzall to lol.

Also i was contemplating putting the 205 from my f100 frankenstein. I thought it would have had more problems fitting with the 205. Obviously i havent sat down with a tape measure yet.

I take back my statement about total driveline length bein fine regardless of length. Has anyone had problems with the gas tank bein in the way of the c6?

part number for bc bronco adapter--11-82010

header http://www.summitracing.com/parts/HOK-6133HKR/?rtype=10


frame will require light trimming and slight rolling/cocking of the engine depending on t case choice.

205 can be a bitch with an e4od, doable though with 1310 joints.

I wanted it as low as I could on the factory crossmember and yes that make the exhaust a more painful. I should modify my earlier statement. I haven't seen any headers that won't require you to modify them or the frame. Bobby's setup is one of the best I have seen as far as not putting too much notch in the frame; those would be the way to go. I went out side the box and wanted the engine centered and would modify the rest. Also insisted on full legnth headers as well, probably won't do that again. Any of the fullsize cases work really. I'll admit I'm biased to the 205 but really a full size bronco 208 is probably the best way to go.

i ran longtubes originally and hacked a trainload out of the passenger side initially. hard lessons.


the headers i listed are different now, they used to be shorter on the front two cylinders. but they are workable



theres some explanation here

Well just to give a little bit of an update. I got the bronco running and have found my solution for header fitment, t-case fitment and everything else. Im gonna make my ranger fully 1/2 ton. Body swap.
I came yo this conclusion when i was brainstorming about fitment and also the thought that i have 318ka on the original d35 and how my hub bearings despise tbe 37s. So instead of trying to make the half ton axles and drivetrain fit into the ranger frame its becoming an all out body swap. Sorry for being lazy. I like the idea of having a more solid frame as well. Ive been googling everywhere about body swaps but i cant find a complete writeup. Oh well. Guess ill blaze another trail.

SO!!!! You all must think I may be Brett Favre with a Ranger addiction... I recently was on the 3.0 forum because I was putting roller rockers in it and keeping the 3.0. Then I broke a tap in the head. And tried getting it out. But there isnt a way its coming out without putting a new head on it. I dont want to put a head on it. Im going to go with my original plan of putting the 351 in it.

Can you use the driveshafts from the bronco with conversion u joints? Are the flanges the same? I trying to utilize the the parts of the bronco so I dont have to buy a bunch of new stuff.

Since my last posts I have acquired a mustang a9l harness, pcm, 75mm maf, and matching 24lb injectors for it. I plan to jsut splice the mustang harness into the ranger harness and use the truck intake. Its got a 3" body so its got plenty of room.

Again about the headers, why don't people just dent longtubes to fit inside the frame? I understand this may take a little away from the flow of them but its still a whole heck of a lot better than using manifolds, or even shorties (since scavenging isn't as strong) and then you dont have to cut the frame (that would be my last resort). Just saying I shoved longtubes into the bronco frame when they said they wouldn't fit. They came off a 82 f150 4x4 with a 302. They only need a little adjustment on the passenger side where it sits on the trans, but a little heat will fix that.

Is there any cable style trans shifters from the junkyard I should keep an eye out for that would work on a c6?

Ok got to thinking. Tried to find fenderwell headers for an early bronco because i figured the frame width is roughly the same. They discontinued production of them a few years ago but someone on the bronco forums suggested using jeep sbg conversion fenderwell headers. These would also make for easier sparkplug access as i am now the proud new owner of some gt40ps. I grabbed the manifolds out of the explorer also in case i cant get the jeep headers to work. I think the only thing really detrimental to using them would be the coil buckets in the way. I think the steering shaft will have enough clearance to pass through the primaries.

Has anyone gone down this road before?

This is the link to the headers i am talking about.
