20th aniversary 5.0 motor?

[BlueMonster65]

a friend of mine has a dissasembled "gt350" aniversary mustang motor that he is trying to sell. i was wondering if this is a roller motor or flat tappet. he is not sure. also if there is any difference between this block and any other 302 or 5.0L block. for instance if it has a high nickel content and is stronger like the mexican blocks are supposed to be?

I believe it is a myth about the mexican 302 with the higher nickel content. I have yet to see any verifiable evidence. Ie. specs for original manufacture or metalurgical reports. I believe the myth came from the fact that they have a stronger 4 bolt main. Got nothing about the gt350.

The '84 5.0 HO is nothing special. It's flat tappet. Block isn't that strong as well.
