sb or bb?
I am building my 82 f-150 into a toy truck for on and slight off road use. I origanaly was going to build the 302 that is in it. I recently decided that the old 302 might be a little under powered for the 40inch ground hawgs i plan to put under it. I am going to do the straight axle swap with a dana 44 i beleive thats the right axle. would 4.10 gears be low enough with a well build 460 to drive well on road and off, but still have enough power to really feel it in the seat of your pants when you nail the throttle. I have found two 460's within about 5 miles of here i live and they both want 350 bucks for the motor and automatic trany. I one is from an 84 ish lincoln. The other is from a 75 lincoln. which would be the better motor? the one from the 84 i saw and its been sitting for a long time. Also i need a bellhousing for a 460 so that my manual trans will work. any idea's boys and girls????

ford quit putting 460's in lincolns in 1978, so if its an engine out of an 84 lincoln it isnt a 460
all that was available in a lincoln in 1975 was a 460. thats the way to go- and as for gear ratio for 40" tires- go at least 4.56's if not 4.88's or 5.14's... 4.10's just arent enough gear. also for 40" tires that little dana 44 wont hold up long, youd need a dana 60. the manual transmission from behind a 302 wont hold up to a 460, youd need- if its a mild build- a zf-5 speed or an np435. as for bellhousing you need a bellhousing for either a 351m/400 or a 460. youre much better off though with the c-6 auto for what youre proposing to build because itll take whatever you throw at it. if your body is in good shape you could just look for an f350 4x4 with a trashed body and put your body on it... or you could just look for a decent f350 4x4 and be money ahead vs trying to build an f150 into an f350.

I am not sure exactly what the 84 motor was out of. i saw it and it is deffinitly a 460. I am not really planning to off road this truck at all. That makes me think that the dana 44 should be ok. The nine inch in the rear should be upgradable to handle it I think. The truck is never going to see a mud hole. Really the worst it will get is maybe some wet grass or a slick muddy field. No mud bogs! O and as an old saying goes "Its not what you buy...Its what you build!"

the tranny wont hold up to the torque of a 460... and offroad isnt the only place the d44 isnt enough for 40" tires... just running around town is really rough on the knuckles... its also hard to steer.

ok thanks. I was really wanting to stick with the front axle riding on coil springs so I will see what I can come up with. Do you think that just a mild build would be enough for what i want? I started out wanting to go all out, but now i am thinking that maybe a good set of aluminum heads with big combustion chambers so i can run pump gas would be fine. How about an intake thought or cam?? This is about the engine and not so much the truck it self.

That is very true but part of the reason that it won't see mud very much is because of all the money I will have in it. All of my friends have always had the big play toys. well i would like to look down on them for once when we go cruising!

If I were you I wouldn't worry about the trans you have. If it's a borg warner 4 speed like you say, then it's a T-18. Strength wise it's on par with an NP 435.
To run this trans you have to have a bellhousing that matches the 460 you want to put in. If you have an early 460 (internally balanced) you use a 390 flywheel and a 351M/400 bellhousing.
If you have a late 460 you have two options. Either track down a flywheel and bellhousing for a 83-87 460 with a 4 speed or have the motor converted to internal balance and use the 400 bellhousing and 390 flywheel.
As for tires and axles you hear all kinds of doomsday prophecies about running anything bigger than a 33 on a D44 under a fullsize truck. I ran 35's HARD and never had an issue and I personally know a guy that was running 40's on a 79 F-150 street truck with a 44/9". He had one issue that wasn't even really that bad. He had to put balljoints in the 44 every 3 years. The lower joint will get loose from the added stress of the bigger tires.

You can play all night in the mud and not break stuff if you use a little common sense. Snatching a big fwd around on the pavement will do more long term damage than playing in the mud. Sooner or later you will have to prove what you got.

what is a dqt tag anyway?? any way if i put a set of aluminum heads with the intake and exhaust ports in the same location. plus a edelbrock air gap intake and a 750 holly carb with a cam shaft to match. would this set up work well? I have stepped my goal down to around 450 horse power. That would be enough to get the job done. i want to run on pump gas too so thats why I think a set of aluminum heads with big chambers would work well. also, I found a bellhousing that is supose to fit a 460. The same guy also has a 460 from an 84 f-350 dually with a stick only its two wheel drive and has a hydrolic clutch. Could I use that motor with its fly wheel and clutch in the other bellhousing he has that is for a mechanical clutch? Then put my t-18 trans behind that?

thanks for clearing that up for me. actually it will be more like a walmart parking lot truck!!! lol! Thats where we always meet up. Anyway. Would the fly wheel from a externally ballanced 460 fit in a bellhousing for an internal balanced 460? the 460 form the truck is externally ballanced but I heard the truck motors had better rods. Is this true or is somebody just blowing steam?
