5.0 HO blocks diff. from Non-HO blocks?

[DFG 5OH]

Are 5.0 HO blocks like whats in the Mustang GT, different from a 5.0 thats in a Lincoln Towncar? Or are the blocks the same. I know the heads/cam/intake are different. Would they ahve different pistons? Or is everything heads down the same?

I think it all depends on the years of the different cars you're talking about. Like the older 5.0 stangs are non-roller. Newer ones are. Same for other cars. I have a '97 Mountaineer block that is roller, a '95 F-150 block that is roller, and a '69 F-100 block that is non-roller. I do know that Towncars and Thunder Chickens came with rollers ..... but I don't know if early one's did or not.


BTW, if anyone's interested, I'm willing to get rid of these blocks.

Blocks are the same (assuming they are both roller) as fas as internals, I would also assume ford would use cheaper (meaning weaker) internals for there non sport car blocks.

Okay, sorry... I misunderstood your question. I don't know what the differences are between the motors (camparing roller to roller or non to non). I do know Ford liked to change pistons around in Stangs, so I'm sure the other cars have their differences, too.

The SO 5.0L has cast pistons with no valve reliefs(you can run an HO cam w/o problem but not much else), crankshaft is same as HO.
