I wanna put a 6 inch lift on my bronco. It has a 4.9l which I will be swaping in a 5.0l down the road. But with a 6in lift do I have to get a longer rear drive shaft and or a drop down bracket for the transfer case? Right now I have 33s but will be getting bigger ones down the road. This is just a mud truck so I will be sticking a little money in it once in a while on up grades. I know about diffs. And stuff with bigger tires.

I'm just getting feedback right now before I make my decision to getting he lift kit. I have talked about getting a 4in kit for my other truck but people have talked me into getting the 6in.

 

you wont need to make any driveshaft modifications what so ever. install it and have fun.

by the way, keep the 300-6. its a better motor. if you want a v8 skip the 5.0 and go with a 5.8 or 460.

 

The only thing I might do if I keep the straight six is upgrade to a two brrel Carb. The one I got on there I don't know it's hard to get to rebuild kits for hard find the right kit for it. Its got the t-18 warn 4spdwith granny gear . I know the six is a good motor cause I got it in my 93f150 and I beat the hell out of that thing, its been rebuilt once cause I hydro locked it mudding and that's why I bought the bronco.

 

I'll second the notion to keep the 300... I mean, trading 2 cubic inches for less power on the bottom end where the heavy Bronco really needs it will basically gain you two cubic inches, two pistons, two more spark plugs to buy and about a 12% reduction in mileage. Besides, when was the last time a 302 went 250,000+ miles before needing an overhaul?

 

yeah my friends dnt think that motor will turn big tires in the mud but a 6cyl with a granny gear should i thought.

 

It will, and it'll do it a whole lot better then that 302.

If you were thinking about a 302 then go 315w. They required the same changes to swap in, but the 351w is a beast compared to the 302.

 

go with a 4brrl carb and the offenhauser intake.

 

4brl for the 4.9l or v8s? I did have a 4brl offenhauser for a 4.9l but I sold it cause I had no use for it then I got my bronco a year later. Well a 5.8l would be what I would go with but I got a 5.0 I bought to switch into my 93after I hydrocked the 4.9l in it, them I just rebuilt the 4.9l anwys. So now the 5.0l is sitting and I know I can get a lot of parts for it

 

Because they never had a 300 six before that's why. With a few bolt on mods they become a real torque monster. I am running a warmed up 300 backed by a granny four speed in my 84 1/2 ton pickup. It's been punched .040 over, mild cam, headers, Offy intake, (when I had it running last) it had a Holley 350cfm 2bbl (it's getting a 4bbl), free flowing exhaust. It never lacked power for my needs, when I had it on the road or in the woods (been in the shop since 2006 being completely restored) I had a 4 inch suspension lift with, 4.10s, locked rear, LS front with 33" Mud Kings. For a six cylinder, that truck was an animal! It was pretty quick for what it was too, it was nothing to toss it sideways around a corner on dry pavement. I raised a lot eyebrows at the mud bogs with this thing. I agree with everyone else, if you must have a V8 go with a 351w or a 460.

I wouldn't go 460, than you have to swap transmissions too.

 

True, but actually it would only be a bellhousing (IIRC he said he has a 4 speed manual) and motor mount swap to drop a 460. The T18 is plenty strong enough to handle a big block. I am a huge fan/ supporter of the 300 six... but the 460 is a really nice motor for a mud bogger. I'm running one in my 79 Bronco and absolutely love it, there's never a lack of power that's for sure ! Really it doesn't matter which motor you go with, the 300, 302, 351w, and 460 were all great engines capable of making good power and standing up to the abuse of 4 wheeling.

Never met anyone with a 300 that didn't love it..
think about it man, if toyota people can build fully caged crawlers with 38'' tires and go through anything with little 2litre moters, you think a 4.9 litre i6 can't move around a Bronco? It should have no problem with 3.55 gears and 35 or 38'' tires.. wont be super fun on the highway, but kick your t-case into 4-lo and you're just fine going up any incline or plowing through mud.

from a 4'' to a 6'' you need extended brake lines, you're cutting it really close with most 6'' lift shocks.. and you will probably want to do something with your steering. Bumpsteer with a 6'' lift and only a 4'' drop pitman arm can be a pain offroad and you will tear up steering links pretty easily. I did a knuckle flip on mine, was well worth it.

 

I love both of mine, both have manual trannies behind em and good gearing... I couldn't be happier. I was at a mud bog a few years back with my 84 F150, I ran the pit a few times with it. I was talking to a guy out there who just happened to be a Chevy guy (with an open mind... weird huh?) He asked me what I had for a drivetrain in my truck (engine, trans, gearing, etc) I told him I still had a six cylinder it, "300 six?" he asked... he replied "Oh you do just have a six cylinder, you have THEE SIX CYLINDER!" To say the least he was impressed... that made me really proud to have one. Unfortunately you'll always have a V8 zombie out there trying to talk it down. If you ask me, the 300 Fords don't get near the recognition they deserve.

 

the overall design of an inline six is just better then your v8's. the motor can be built to scream, just like any v8. and honestly cost you the same coin in the end.

personally i would own a 300-6 4wd before going to a v8 my next go around. i love how you can climb right into the engine bay and work. there are some 300-6 performance based website floating around the web i suggest you check them out and get the christmas list started :-)

 

Yep, there's a couple guys on this website with warmed up/ built 300 sixes... they're making some pretty impressive numbers at that. If you hang out in the inline six forum you should stumble over Colonal Flashman, he's running a sweet setup in a 58 Mercury M100. He has a couple videos of his truck in action on youtube as well, man that thing is nasty sounding for a six These engines do respond well to mods, especially the older carbed engines when you free up the intake and exhaust system on them. I would have to disagree on cost of building an I6 up versus building a V8. The hp/ tq gains of a V8 are better than an I6 dollar for dollar, I blame that on supply and demand. I wouldn't let that shy me away from building something cool and unique, and it's been proven time and again they hold up great even when they're built up. I am doing a frame off restomod on the 84 F150, I fully intend on leaving the 300 in there... just something different.
