Someone here knows the answer, F600 Ford question

You guys know pretty much everything, well, at least the guys in our group collectively do! So, 1978 or 79 F600 dump with a 370 "Lima" gas engine+, 4 speed/2 speed rear. Gotta bad engine. Outside of another 370, which don't seem real common for some reason, what other engine is a bolt in replacement? This is a farm dump for hauling rock, dirt, wood, manure. Not really an over the road truck initially, but maybe someday. I can rebuild, but I thought I was buying a better engine than I did. I know some of you have the answer!

Tried the forum I get all my other Ford truck answers on, but they don't have a lot of larger gas engined tuck traffic I guess.
 
They're in the 429, 460 family.

But there are also pass and truck versions with lots of deal killer differences.

And Ford has a reputation of moving the bell housing bolt holes around for some reason.

So, will they fit? Don't bet on it, but a place to start.
 
The guys below are right. A 370 429 460
are direct bolt ins. Trucks have a
different front cover / water pump. But it
will work on a car pickup block. Or you
can just use theirs. First thing I did was
to order a 550 holly generic carb. Wakes a
truck up. A 429 really wakes up a truck up
that had a 370 in it.
 
You are right but a 370 is same as a 429 460. You can use the 400 351 modified block. It will kinda bolt to a 460 bell housing. Not all the holes line up. Also flywheel is hard to find.
 
wellin the automotive world, unless the truck industrial was seriously different, which I am not entirely certain, a 429/460 would be entirely interchangeable. As far as going to a 429, those were neutral balance engines and not exactly manual transmission compatable. as for a 460, usually easier to find and if the front crank snout has the weight on it then you must use a weighted (shhaker) flywheel, if it has a smooth crank sleeve behind the balancer then a neutral balance flywheel must be used. This change was made throughout the 1979 model year. all 460 AFTER 1979 have shaker flywheel, and weight on crank snout, all 460/429 1978 and before have neutral and smooth on crank snout. 1979 had both as they used up all of the earlier assemblies.
 
I'm thinking (but not sure) the 460; while it would be a direct bolt in; was only offered in the light duty (car/pickup) version. This would mean it has the light duty crankshaft in it.
Only the 370 and 429 were offered in the car/pickup and the heavy truck version with the beefier crankshaft.
You can tell the car/pickup engines from the truck engine several ways.
Bigger oil pan and exhaust that exits in the center come to mind.
 
I'm not an expert but my Father had a 1976 F-600 with a 330 v8 and four speed with two speed rear. Bought it new to use hauling logs and fire wood he cut in the woods and hay in the summer, had a 16 foot home made wood flat bed.
 

As for a direct bolt in engine the 429 truck engine is the only one that will replace the 370. The truck engines have much larger crank snout and different timing cover, none of the trucks pulleys or front mount will work with the smaller pass car crank.
You can use the truck crank in a car block to build a 429 truck engine but to use a car engine you'll be doing a fair amount of fabricating.
If you can find a 331/361/391 with the bell housing and all of the accessory brackets you can do a full swap to a FT engine using your transmission, but even then there could be a wiring issue.
Does yours have electronic ignition or points, there's a gap in the years model I'm familiar with, we had a 75 model 391 with points and the 81 with 429 had electronic ignition, I'm not sure if any of the FT engines came with electronic ignition of if the Lima engines came with points.
Personally I'd look for a 429 truck engine.
