1965 F250’s Rejuvenation

Stick with the 300, plenty of potential untapped in there, and with fewer hassles from the unsuspecting authorities than they'll give you making an engine swap. :whistle:

I think you can swap any motor that came in a model from new with any other motor that came in there with out any drama

So if a V8 was a option I feel (just talking out the whole in my hat) that you can put any of those motors in without drama

Engine swaps are easy, it's the legal eagles that make life difficult.

Lot of info on the 300 m0t0rs on US U - Tube posts Urchy.
Popular, easy to work on, parts available.
Heavy on fuel and run out of puff at high RPM.
They have good torque at normal operating speed.
Mate still uses his F500 in the steel construction business
and finds it handy and reliable.
Buy a lot of fuel and parts with what would be spent on a
transplant and compliance. Just what hear around. Paul.

Forgot to add, main advantage for truck work is the 7 bearing crank.

dad had a '68 F700 with the 300 in it, We repowered it with a 351.. All we really gained was a nicer exhaust Note...

The last time I went through an engine swap was as described. If it was an option for that make and model then it was almost a straight forward exercise. However you also had to fit the larger brakes and heavier suspension that went with that engine, if there was a difference for your truck.
I did mine but b are in mind this was 50 years back and was a very simple upgrade with the RTA at the time

Thanks all. Have been given a number to a mod plater who does a lot of engine conversion plates for classics, will call him tomorrow to hopefully get a path forward.

I haven’t written the 300 off yet. Will be glad to get these valves in whenever they arrive to see how it actually runs, it may stay in there yet. If it does come out I have plans in mind for what I will do with it. It will get a birthday before being utilised in a future project.

Yet to hear back from the mod plater. Seems they are all a bit like that.

The parts from Rockauto arrived a couple days ago. 8 days from the day sent it. That’s awesome. Had many things take longer when ordered within Australia. Will certainly use them again. Need to order some door rubbers, windscreen rubbers etc in the coming days. The parts all seem to be correct and arrived in good condition.



Started cleaning off the old head gasket today, man is that hard going. 1 hour in and this is where I’m at. Certainly glad most of it came off with the head. Would be a headache and sore back if it was mostly on the block side. Hope to have some decent progress in the coming days.

I use this stuff, spray it on and wait a while, maybe 10 minutes max, I cant remember and it seems to soften most hard as a rock gaskets



If the both surfaces are cast iron I use a wire wheel on t he grinder and have had no ill effects, I wouldn't use a wire wheel on aluminium or diecast
