302 4speed
well I got myself another dentside,a 78 4x4 and someone put in a 302,4spd 205 combo out of another truck.I'm unsure of the year that the engine and such is out of,all I do know is that I was doing a few things and the throttle stuck wide open and I now have a turned main.so instead of building another engine I was thinking of using my low millage 302 from my 78 2wd truck seeing how its comming of the road here soon anyhow for the winter and I'm building a 306 for it while the snow is on the ground.my 2wd is an automatic.other then needing to get a pilot bushing for the end of the crank and switching flywheels can anyone think of any other problems I will encounter?I am unsure of what 4 speed this 4wd truck has.I asume it came out of an early 80's truck.

make sure the 302 in your 4x4 is NOT a later model engine since the flywheels have a different inbalance then the older ones. without looking I can't remember the exact year they switched from 28 to 50oz inbalance but it was in the mid 80s sometime so if both are 70s era engines you will be ok but it's worth the time to make sure.

well I know the engine in my 78 2wd is the original engine,but the one in the 4wd I just got I have no idea what its out of.I'm not sure where to check the 302 for numbers to see what it came out of.I am going to try and get ahold of the previous owner to see what the engine came out of,the truck originally came with a 351m according to the vin.so who knows,and I would say that the truck was also originally an automatic.a few variables with this one.but I am going to drain the oil out of it tomorrow and see what it looks like but I'm pretty sure its a spun main.no noise but just over idle it shakes bad and gets warm quick,not overheating but warm fast,and once it got warm it had almost no oil pressure.

Just checked it out. It was late 79. You should be good to go using your 78 stuff.
I did the wrong flywheel once. You know immediately if it's wrong. It's a really nasty, car shaking vibration. DO NOT! run it for more then enough to know that it is wrong. It will heart things quickly and badly. Expensive things.

I thought it was mid 1978 when they changed weights. Sure makes his truck a crapshoot on flywheels.
Just checked it out. It was late 79. That info is in-correct.

1973/79 F100/150, there are THREE different 302 flywheels.
1973/76 and 1977 before serial number Y80,001: D7TZ6375C / Marked: D7TA-GA or C7TE-A.
1977 after serial number Y80,001 & 1978's before serial number BE0,001: D7TZ6375G.
1978 after serial number BE0,001, all 1979's: D8TZ6375A / Marked: D7TE-GB.
Where is the change in late 1979? No see um.
1980 302's used D8TZ6375A, but only thru serial number GG0,001.
After that serial number break, there are several more.

You sure? I'm refering to the balance weight issue and I'm fairly certain that that happened once in the late 70's.
OK it was 1981 that it was changed.

Since I gave the parts catalog reference, all you have to do is go to a dealer, look in their catalog and verify the info for yourself.
Since I was a Ford partman for 35 years, I knew in an instant that your info was in-correct.
This isn't the first time I've typed this info on FTE, it's prolly closer to the 5th time.
Where did your info come from??
BTW: Monsterbaby sez I sometimes type too much info, but in this case, I typed every dang thing I could find.

Yeah, numberdummy, seriously, apologies for mocking you and such. The info you give is extremely valuable. Clears up a lot of Ford trouble. I am an a-hole sometimes. (Just don't ask my wife how often.)
You throw a lot of part numbers at us. What flywheel part number did the change of balance happen? For trucks and cars.
