I have a 78 4x4 with a straight 6 and 4 speed. I am needing a new motor and found a good deal on a 360. I have never swapped an engine before. What parts do I need to make the switch? I am wanting to keep my 4 speed. Any help is appreciated.

 

You will need a 360-390 bell housing and engine perches for a 360-390 .. The 360-390 was not offered in 78-79 so whether the perches from a highboy chassis will work for you is the big question .. I know there are others who have done this swap so take a look for other threads in this forum ..

 

Just rebuild your 300. You'll be real dissatisfied with the mileage out of a 360. Especially after all the hassle of a swap.

 

x2 on keeping the six. A lttle work on the six will give you a much more satisfying result.

 

Sometimes what appears to be a 'good deal' is not...

Gotta get an FE manual bellhousing, engine mounts, radiator size, trim the radiator opening of the core support, gas pedal arm & linkage, clutch linkages, exhaust (front half at least), get a clutch, flywheel, pressure plate, and all the little incidentals.

2x on rebuilding the 300.... Heck, get a long block from O'Reillys and you'll be miles and dollars ahead.

 

And on top of all that a 360 is a dog of a motor. People talk about the 351m being a boat anchor but a 351m is twice the motor a 360 is.

 

.. Compared to the FE, aftermarket support for the 351M/400 is lacking.

Gimme the torque of an FE please.

 

Would you like to sell the i6 engine perches ? thanks Will

 

I have a 300 in my 77 F150 and I agree with the others here to keep it but should you decide otherwise please do not scrap it, somebody will want it I'm sure

 

I have been around a few 351m's and now own one, ill say they are monsters despite the bad rep.. I have to admit, even though I swapped a 300/6 for a 302 the 300 is by far my favorite motor and there are PLENTY of performance upgrades available.. the 360 is not an absolute dog by ANY means.. I know a man who has had one in his yard wrecker for the last 20 years and it has plenty of power in front of its 4 speed..

 

The FE is the way to go. 6 cylinder engines should come with a set of pedals. Not to mention the cold blooded nature of a 6.

 

Sorry but I'll bet a 300 six will out tow a 360 FE any day of the week. They might not be fast but they will tow damn near anything and still get good mileage. Torque is the name of the game here.


P.S. Not all sixes are dogs either. There is a member on here with a 300 6 that would blow most V8's doors off. Also there's my cummins 6 banger but that's a whole nother animal.

 

The 300 6 is a fantastic engine and i would love to have one. The 360 is a torque motor 2 but with the difference in gas millage there is no way I would remove a 300 for a 360. Now if the deal was for an older 390 say mid 60s thats a hole different story

 

Thanks for the input. I will keep the 6. My only problem is I have 3 different shops that want close to $3,000 to rebuild one.

 

I 100% disagree.. besides my 300 does have pedals. I have watched a 300-6 (stock) boil 38's on dry pavement vs a Chevy 350 bog in second in a mud hole.. the 302 is the next weakest runner up IMO.. but back on topic zgraham, that sounds a little high.. is the motor running?
