What are the main differences between cast and forged pistons , ive heard forged are better and there is quite a price difference between the two ? are cast really that crap ? i have 1641 forged pistons at the moment and although there not too bad might have an offer of some new cast 1600 B+P's as the engine is appart at the moment and could do with changeing the rings and for some reason no where seems to have any for a 1641 at the moment was thinking of going back to stock pistons ?
