Welcome to FTE!

The 300 sounds cool. That was my #1 criterion when I bought my truck. Another truck would've had to have been real special or a helluva deal, to get me overlook a V8 under its hood.

 

Welcome to FTE yea lots of busy threads going on here, better to dive right in and set up your own thread that way it will get a look my most of us.

So FE/FT big block to 600 6 cyl. Well I have no experience on that swap and what belhousing/trans will, but I am sure someone will come along that does.

The 2 links below are the Performance, Engines & Troubleshooting forum.

Different bell housings, won't interchange. The 300 does share it's bell housing pattern with the later 289, 302, 351W and 351C. Oh, and the very obscure 255. Engine towers are the same from the 360 and 300 but you will have to move them ahead and I've done that when all the bolt holes weren't in the frame.
The small block V8 flywheels will bolt on but don't be tempted to use one. Get the right one for a 300.
If the 300 is just a basic long block, you have a lot of parts to find and would be better served to find a donor vehicle for all the pulleys, brackets ect.

 

Thanks for all the info so far! The 300 was rebuilt by my grandfather and from what I’m told used to run an irrigation pump. All of the pulleys/fan/alternator are already installed. I also have a new clutch sitting on my shelf ready to go in. I will have to order manifolds and probably motor mounts. (I’ve never built any and though my fab skills aren’t bad, they aren’t exactly pretty)

The next step is to pull the 360 and trans, save whatever is salvageable, then it’s back to the shop to start building the engine. We’ll deal with the transmission jumping out of reverse another day! 😅

Updates to come!

 

Stationary engine? Make sure it's not a reverse-rotation or anything crazy like that. Not sure if Ford even did that with these engines, but it's something you'd definitely want to know beforehand...

As stated above, the 300 uses the same bell as a 302 and 351W - and I think the 351C. But not the 351M...

And regarding the flywheel, I think you can take a 302 or 351W flywheel, and have it rebalanced to a zero-balance state. Then it will work on the 300.
302s are either 28 ounce, or 50 ounce imbalanced starting in 1981 or 1982. 351Ws are all 28 ounce.

FEs don't share the small block bellhousing bolt pattern? Do they use the 335/385 series (351M, 400/429, 460) pattern?

 

FE engines have their own bell housing pattern.
And you won't have to fab engine mounts. Yours are correct for the 300. They just need moved forward. Buy the rubber mounts to bolt on the engine for the year the truck is.

 

There are two types of F100/350 FE bell housings:

1) 1965 F100/250 4WD; 1965/66 F350; 1966 F250 4WD .. These trucks used the same engine mounting system as 1961/64 292.

2) 1965/66 F100/250 2WD; 1966 F100 4WD; 1967/76 F100/250 2WD/4WD & F350.

 

 

Not the rubber part, the metal towers that are bolted to the frame that the engine sets on, same for 360 and 300.

 

Progress is being made!! I was finally able to get into the junkyard and get *not bad* set of manifold, they're not what I had in mind but they'll work for now. I was actually able to buy an aluminum bell housing out of his personal stash. If we're honest it's way to nice for my build but I'm not complaining. I did make a bit of a saddening discovery the other day, unfortunately my flywheel as a bit of a groove in it from back in it's irrigation days. A trip to the machinist should resolve this as it's not very deep. It will be a bit of a set back though.

 

Was this on an irrigation well in West Texas? Perhaps running on natural gas?

 

 

If they take much off th flywheel, get a flywheel spacer shim or you might find the clutch adjustment rod is too short.
Not that it really matters but the carb base changed in 79 and got larger so early and late cabs do not interchange. If you didn't get a carb with the manifolds, you will need to know this if you are sourcing a carb.

 

When run on natural gas or propane the engine is clean, lacking carbon buildup but the valve guides ran dry, lacking good lubrication. Not a real big deal if it had a valve job.
