ok bear with me here grammers bad , hope you can under stnad what im trying to get acoss

ok right now i got a 83 ford F 100 stepside ,you know with the wood bed short w/base.
i been haven thid truck since 2001 i changed amlost every thing i got a hot 351w in it with edel alum heads fmx trans its got a 8.8 rear i put a limited slip in it with 3.27s i get 12 mpg hiway that suck that motor i had in it was 351w .060 over flat tops i had 10.7 to1 compression , i had solid roller cam in it with rpm intake head are edel rpme too.has headders..o cam specs where 246/256 .050.lift was .601/.588 and got 12 mpg hiway with 3.27s i tryed a 1850 holley still got 12 mpg my 3310 750 go tthe same thing

ok i throw i rod in that motor V

so built i mild 351 .040 over with hyd cam 204/214 .050 lift .447/.474
with perf intake .600 carb i even took the 2800 stall out of it ..it gets the same mileage hi way 12 mpg..o the head on this motor are e7's with the exhast hump ported out..

so i built a 408w now it on the stand ready to be put in.
spec are
408w 9.5to1 compressiom
eagle cast steel crank
sir rods
kb pistons
heads are same edel rpms 202/160
intake is rpm edel
im going to run the 3310 750 on it
cam is another cam motion solid roller specs 231/236 .050 lif is 591./.544

i ws going to pu this in my 83 f100

but now i just got a 88 ford bronco full size 4x4
its got 302 with blown head gasket whick i just changed it not finshed getting it running yet ,little more left to do.
i did this to see if every thing working on drives good
it got an aod trans with the transfer case.
im new to the 4x4s

i got a discion to make you think it should put the 408w in the 83 f100 .or put it in the 88 bronco?

the bronco has aod i think its got 3.55 in it ,i think an aod has a .67 od. that makes find drive 2.37

so do you think i will get better than 12 mpg with the 408 in the bronco?

i lkie haven a bed in my 83 p/u im not sure about the bronco has for hauling large stuff?

what should i put the 408 in

i like the bronco cause it got more room , well back seat plus if i haul motor in the rain they wont get wet if it rains

p/s how does the 4x4 work? it hae 2h/4l , 4h and N.

whan i lock the hubs in the front i can still turn the front drive shaft at will . it like the ft whell arent locking up? or does the wheel have to be moving? that what someone told me? dunno?

changing the fi to carb is no prob for me ..thw 408w in the bronco should get more that 12 mpg on hiway right?

what gal gas tank is in the bronco?

please give me soem tips im new to this 4 x 4 ..thanks sorry so long,i hope you can make out what iam trying to say..thanks gary!

cause if i can get 18 hiway or so out of it , i can sell my 83 f100 for hauling in my 84 500 sel m/b for vactions.
and park the 03 cobra so the mileage will stay low.
i would be getting in it on the hiway.
ill prob. harley ever go mud bogging , but i never had a 4x4.

i finshed it up last night , it was late 11;00 its not getting no fire, theres 2 plugs that go to nothing it looks like ?

when i get it running im going to hit the instate and check my mileage! for 60 miles..my truck83 f100 with hot 351 when 60 miles in had to put almost 6 gals in it.

the same was for the mild almost stock 351 too.?

i think the 408 may just get better milegae? cause its not bogging the motor down?

im on a brnoco forum ,,but theres really nobody there:shrug:
