302ci Interchange help request
Ok,
__here's the scoop.
My 2WD 77' 150 W/ 302, C-4 HD'trnz, 9 rear.
Is dying horribly; eng. has bad cam-bearings, Tranz is beeding from most of it's body seals,
axle may be in need of rebuild (won't know untill tranz is taken apart.),
& brakes are; well...have seen better days. (but can be put on back burner.) Onword here.
What I'm currently putting my focus on is the eng. dilemma.
I'm person of little funds. So getting a remansed eng. -or-
rebuilding the old one is something that is not accomplished quickly, for me.
In short; I'm looking for a part-yard eng. replacement to get the ol'dog up'n'going again.
What I would like to do is keep the carbureted fuel sys.
But, change over to a surpentine belt setup.
What years of surpentine belt 302's can I use.
So all I have to do is just drop my stock intake on, & run with it?
I'm not in too much of a hurry to put one in as of now.
I'm doing research at this point.

The serpentine set up showed up on the 82 & later 5.0 302's. The chief difference between the older 302 and newer 5.0 is the external balancing. As long as you use the Harmonic balancer that comes with the newer engine, and use a flexplate with the proper 50oz counterweight (older 302 has 28oz), you should be fine. Other considerations. The serpentine system spins the water pump the opposite direction. So if you ended up putting v-belts on, replace the water pump for proper rotation. If you are able to leave the serpentine system in place, then no problem. There might not be a place on the timing cover of the newer engine to bolt on a mechanical fuel pump. You might have to install an electric pump and flow regulator, or put an older timing cover on. This can be a PITA because the water pump bolts to the timing cover and sometimes the bolts that go through the water pump and then through the timing cover, corrode and snap. I made the mistake once of replacing one of those bolts with a brand new bolt. Turned out to be a hair too long, and when I tightened it, it snapped a piece of the block off. Pissed me off enough to go to the wrecking yard and convert my truck to 390.

Thanks,
__this a big help.
You answered the lot of Q's that I had to ask.
As for the timing cover prob's. I find that powdercoating the timing-cover is money/time well invested.
For the bolts, finding one's that won't rust useally isn't cheap. Only kind that I know of, are stainless steel.
