93 over 90

Found a 1990 5.0 and I am debating over the 90 or a 93. I heard the 93 engines (alumn over forged pistons) dont last as long is this true?

RE: 93 over 90

the 93s have hyperutetic pistons, which are supposed to last longer.

the 90 has forged pistons, which are stronger.

they are forged alum! steel would weigh a ton hyperuretic pistons are better than cast and less than forged they are fine in a n/a application(im sure plenty of people here have boosted/nitrous 93s)

Ford last used steel pistons back in the 30's. Only industrial diesels currently use them. Look for steel pistons to make a comeback due to modern technology and stricter EPA requirements
