The HO version of the 5.0L engine was more powerful because it had 17 more horsepower than the previous 302.
aluminum intake manifold, hard-hitting camshaft with double row roller timing chain, CR sandcast pistons, and valve stem oil seals with nylon. The camshaft used in the 1982 HO engine was the same one that appeared in the 351 Windsor two barrel passenger V8. Others knew it as the 1973 Torino. It was not a marine cam as had widely been rumored because the torque of the marine cam simply didn't cut it. cast iron exhaust manifolds with single muffler and dual outlet exhaust,

Correct me if im wrong.

For 79 the 5.0 had 140hp and a firing order of 1-5-4-2-6-3-7-8, thats the non-HO firing order. It uses a D8VE-6010-AA block casting with a D6OE-6250-AA cam and D9TE-6303-EA crank. The flywheel uses a 28oz. balance.

Cam specs:
Intake: 16 open / 45 closed / 0.237"
Exhaust: 57 open / 19 closed / 0.247"
Duration: 241 degrees Int. / 256 degrees Exh.
Valve lift: 0.379" Int. / 0.395" Exh.
Overlap: 35 degrees

For 82 the 5.0 had 157hp and a firing order of 1-3-7-2-6-5-4-8, which is the HO firing order. It uses a E0AE-6010-DD block casting with a D3OE-6250-AA cam and E1AE-6303-AA crank. The flywheel uses a 50oz. balance.

Cam specs:
Intake: 15 open / 65 closed / 0.260"
Exhaust: 68 open / 26 closed / 0.278"
Duration: 260 degrees Int. / 274 degrees Exh.
Valve lift: 0.416" Int. / 0.444" Exh.
Overlap: 41 degrees

If i read right they both use the same pistons and heads.

The Standard Output 5.0 uses a different firing order, pistons without valve reliefs, E6SE heads, a more restrictive upper intake and throttle body, 14# injectors, and a single roller timing chain.

The HO uses E7TE heads, pistons with valve reliefs, a larger cam, a more free flowing upper intake and throttle body, and 19# injectors.

Get the HO rebuild kit, or youll regret it. You wont be able to run anything larger than a stock cam without having to worry about piston-to-valve clearance.

ok thank you that answers my question. if i post a picture of the block and pistons whould somebody be able to tell me if its ho?

Best thing for you to do is start a new thread on how to identify your block or do a search...I know this has come up before.

Post a picture of the top of your piston, and i can help you.

If the engine is out of a mustang, or lincoln LSC, its an HO, but i can confirm for you.

If its not an HO, you can still use the HO rebuild kit, with pistons, and make it 100% HO.

when did they go to the 351 firing order on the 302? 82? what year is your car?

GeraldineRyder

well, i just came in from the shop and i found something out, the guy who gave me the engine LIED to me, i hate beeing new to the ford scene, but i got the engine broke almost all the way down the i took the lifters out and THER TAPPET lifters not roller, so can i convert it to roller or should i just find another motor thats roller??

Are there holes in the lifter valley at each end of the block that are threaded? If there is then it's a roller block, those are there for the spider hold down. You can build a decent flat tappet engine your just limited to less agressive cam profiles and you must install new lifters with a new cam or they will destroy each other. So when removing the lifters mark each as to where it came out of because you must put them back in the same location.
