LA318 Pistons for performance build????

318ute,
This is what we use for mild race and street use, we use 86 -90 pistons as they are .020 taller compression distance than that of the old LA engines pistons. Then top that off with a set of 302 heads mildly ported and you have a combo thats good to over 400HP. The pistons can be either cast or hyperutectic styles, but for the weight savings I would use the hyper's, as they are stronger than the factory cast too. You can also run NOS too in moderation if you so please. The cost is less than that of forged, a set of cast pistons go for around $80.00 to $100.00 and the hyper's are $190.00 to $210.00 depending where you get them from. Hope this helps.
