I don't think so.

The 3L did not get the revised pistons until early in the 2000 model year. Though 2000 seems to be the bastard year for the 3L.

Pistons changed, heads/intakes changed, some had coil on plug, some had a combonation of parts. (clearing out the parts bins I guess??? )


Ideally a 2001+ oval port 3L is the best choice for any 3L build.
More "ideally" yet would be it's from an Escape/Tribute. (upgraded oil pan, pickup, P/S pump & pulley, new front cover, etc)

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
