We really need a lot more info. What is your intended use for the car? Are you wanting a stock rebuild or more power? Stock or aftermarket heads? What is your budget? What transmission?
I would suggest finding a local engine builder and consult with them. Based on your location you should have plenty of options.
Street and strip and more power if i read right stock heads for the ho are 351w heads right? Im a diesel mechanic and rebuild motors and have built a few gas burners but dont know the 5.0 HO to its entirety... and buget is obviously low lol im a diesel mechanic... lmao
If you are assembling it yourself I'd assume you will at least need machine work done. It's really all going to depend on your budget. Obviously the tighter your budget, the more compromises will have to be made. The cheapest thing to do would be to have the block honed .005" and throw in new rings and bearings. If you wanted to spend a little more you could bore the block .030" and bump the compression up a little with a better piston. If you wanted to go deeper down the rabbit hole you can buy a complete rotating assembly but 302 blocks like to split in half between 4-500hp. If you were going to spend that much money I'd rather put it into a 351 block. As for the heads, you could do a simple valve job and new guides, you could go to bigger valves with some port work, or go to an aftermarket head.
Personally I would bore the block .030" with a better rod and piston and put some good aluminum heads on it and have fun. 300whp wouldn't be too difficult.
Ok thanks whats a good brand for the pistons and an overhaul kit in your experience? I was alsothinking about a carb conversion so i dont have to try to find a comp and harness what are you thoughts there?
Contrary to to what anyone may tell you, there is nothing wrong with a well tuned carburetor. Well tuned being emphasized. That means putting it on the dyno and trying different jet sizes to make it run right. As cheap as wideband O2 sensors are now it's so easy it's almost cheating. With that said, once you buy a quality carb and jets and dyno time you won't be far off from a Holley Sniper system or just keep the stock 5.0 EFI.
If you never plan to go over 350hp and never plan to use any power adders you could go with a quality hypereutectic piston but then you're limiting yourself later. Just pay the money once and put a forged piston in.
Between 9-10:1 compression will make a nice street motor for pump gas.
Well the thing is i have no "allowance " in just tring to compromise overall work with outcome... As i said i am a deisal mechanic now and i am hovering over a 200+ degree motor for 12 hrs a day. I built a regular 5.0 in my pickup and its pushing 300 just trying to see what are the best fits and options for this H0
here's a good parts source...
also, for some reason Ford built those engines with monster bottom ends, they can take huge amounts of boost, they are one of my favorite engines.

and if you are really, really bored and a decent machinist, this would be a great project....these guys always have issues with machining the timing gears though, I would think by now, someone would have the pattern set.
well i will post more info when i get some time but here is one of my project...lol....its a Ford 2.3 turbo block with a Volvo twin cam head...i just...
but..if you insist on the 5.0 here's a build for you
that's a VERY dependable build that is streetable, and reliable..if you wanted you could add some GT heads and it would go even faster, but you'd have to watch your compression ratio on the street a bit. That is my go to cam, for 302s.
So.. a quick look at the FAST rule book says this....M0 (Open Modified) Rules The Open Modified class (M0) is for exotic cars, and cars that exceed any of the above limits, but are otherwise street legal and on street tires. Cars that bump up from M1 also go to M0. For safety, doors, hood and...
