forced indution piston ?

thnaks for the info i was thinking abotu a 318 to a 390 kit with the diamond pistons and just change my whole set up! Im goin to do it right the first time i dont want any trouble with the engine! Plus im goin with a main support also to help with strength! diamond pistons seem to be the way to go the kit im looking at comes with the dish forced induction piston so that may be the route to take whats ur thoughts! And i know yall are prob saying go with a 360 but i have 4 318 blocks and have the set up for the 4speed
