Overhaul kit
Need help finding an overhaul kit for a 1971 f100 6 cylinder. Thanks in advance. Any help would be greatly appreciated. I don't want to buy junk but on the other hand I don't want to spend unnecessary money either.

What is your definition of "overhaul"?
Stick with name brands like Speed Pro, Melling, Federal-Mogul, Crane, Comp, Cams, SCE, Fel-Pro, etc.
You won't know what you need until the machine shop informs you of what is needed.

A rebuild can also entail an oil pump, cam, pistons, valve springs, keepers, valves, etc. How deep into it do you intend to go?
Machine shops tend to get good prices on branded products. Ask them what parts they recommend. You might get a good surprise.

Overhaul can mean a re-ring, hone, bearings, and gaskets. Some refer to that as a rebuild.

You can use stock bore low compression 2 bbl car 390 pistons on a .050 overbore and bump the compression. IIRC it's close to 9:1. Some say you shouldn't bore one over .040 so a sonic test would be prudent.
Anyone running a 300 should spend some time on Fordsix.

Thanks for the input. And no I haven't pulled the motor yet.it locked up on my son. I think it dropped a piston. I'm just doing the research right now on the cost. But I did have in mind to increase the power when I do go into it.

As mentioned earlier, the engine should be taken apart and brought to a machine shop for inspection before parts are ordered. A reputable machine shop can also set you up with a good overhaul kit and many times for a decent package price with the machine work. And with the machine shop supplying the parts they can custom fit the each piston to the cylinder for perfect cylinder wall to piston clearance.

I just read the part that it locked up. There's a pretty good chance that block and crank are junk. Of course he was probably driving along normal and it just happened, right? I raised 7 boys.
