well, i started to work on my project, and i find out my engine is frozen up. I cant get it to turn over. And since this was supposed to be a low budget job, and totally ripping the engine apart and rebuilding it, is not worth my time. So I am changing my direction.
My grandad has a 79 f-250 swb, crew cab 4x4, auto, 400. It was rebuilt by my uncle about 50k miles ago. Grandad bought a new truck, and said he would let me fix the 79 up and use it instead of the frozed up 78 f-150.
the 79 needs a new carb, and vacuum booster\master cylinder. and maybe a powersteering pump. and i remember hearing the u-joints click in the front end the other day, so i guess that would be in-line also. Also there is some rust holes in the roof, and i would have to fiberglass those up. the 79 has an exhaust leak too. i was thinking of pulling the headers off the 78' and swapping them over to the 79, and make it daul. one more thing, are the doors interchangable form 78' to 79'?
now, my question is, how much will it cost me to get the 79 in roadworthy condition by replacing the parts i have just listed? keep in mind, this truck will be used just as off-road ranch use, and fishing trips to the beach. thanks.
Why not drop the 400 into the '78? Cost is relative, depends on if you do the work yourself. The parts you listed are nothing to skimp on either...maybe the PS pump you can...if you can find a cheap carb and rebuild it...$$ depends on a lot of things.
WELL, The '79 is registered and road legal now, and the '78 is a rustbucket, and only good for a pasture blaster/muddbuggy. (which was all i wanted to beging with). but after coming upon the idea of grandads '79, i think its better. plus, the '78 f150 is only single cab. i could haul more junk in the '79 crew cab on a fishing trip. the '78 has a good carb, but its a 4 barrel. as I understand, the stock 400 is only 2 barrel, and i dont want to have to change out the intake manifold.
anyone know of a good carb for my stock 400? (cost efficient)
how hard is it to change out the vaccum booster?
Stick with the crewcab. Most guys here dream of having a truck just like that.
I'd suggest having the 2 barrel rebuilt. The Ford factory 2 barrels are good reliable carbs.
A vacuum booster is easy to replace. Unbolt master cylinder (keeping lines hooked up) and pull away from booster. Remove bolt on brake pedal that attaches to booster push rod. Remove 4 bolts holding booster to firewall. Now assemble in reverse order. A booster for my '73 F100 2wd was about $125 at NAPA, yours should be somewhere around that.
