At the moment I have a 1987 f250 4x4 reg cab long box w/ straight 6 and 4 speed stick. I am possibly trading my sled for a 1977 f250 4x2 reg cab long box with 351 and auto transmission. My question is do I stick with the straight 6 and would I be able to put the 4x2 auto tranny behind it? Or would I be better off putting the 351 in with the auto tranny? I think I want the auto tranny because I will most likely be mudding with it. Or do you think I would want a 5 speed stick (4sp.w/od)? Dad says I can only keep one truck <O</O I will be putting a 4" suspension lift and 3" body lift on the 87 frame before the 77 body goes on. Then 35" bfg mud terrain t/a ko's. <O</O <O</O lemme know your thoughts!! <O</O Thanks!<O</O
351 with a 5spd shouldn't be too bad built properly you should easily see around 15mpg but that depends on the build and all out power monster won't make that and a total economy build will make more.
Well that would depend on the size of carb. Hehe I know I am no help but I really need more information.
Like what is your budget what do you want out of the motor what kind of power are you looking for. How much mechanical knowledge do you have. Will you be doing the work or someone else.
I'll repeat here what I said on the other thread. I can personally think of no situation where an automatic is superior to a manual transmission. Sure they are "easier" to drive if you're in the habit of talking on your phone, eating a cheeseburger, and shaving while you're driving. But if you're actually concentrating on DRIVING you will have more control out of a manual and, with the exception of the modern gazillion speed automatics with lockup torque converters, will get better gas mileage PROVIDED YOU TAKE THE TIME TO LEARN HOW TO DRIVE IT.
ill be doing the work. i just want something that will clean out 38s. and somethin that got *****. lol i do have a lot of mechanical knowledge seeing as how i grew up with like all my dads friends are mechanics almost. and so is he, but ive never messed with trucks or cars yet. i am 16 and currently have no money lol but i may be getting a job at a farm near my house.
1st - Whatever you want to do to your truck, whatever you THINK it will cost, triple it and you will have a good starting point.
2nd - You've got a fairly big project already doing a body swap and a lift. If you try to do an engine and tranny swap at the same time, you will very likely bite off more than you can chew and afford.
I would suggest that FOR NOW you work on just doing the body swap that you want and doing your suspension work. Give the old straight six a chance while you work on everything else. Once you get your body swap and suspension work done then you can re-evaluate your budget and see what else you can and want to do.

manuals are hard to shift when u are mudding. you are way more likely to over rev your engine and blow the radiator hose or blow out the radiator(overheating) and then (a thrown rod). SO AUTOMATICS are the way to go for mudding in my book. When properly installed the allison AUTOMATIC tranny behind the Cummins engine is almost unstoppable.
