i have the l98 5.7 in my gta. i was wondering what kind of pistons this engine has in it. are the hyperpathics or forged??? what style cam is in there???? what were the hp and tq #'s back then???? i know these are a lot of questions but i need help. oh and i tried the search button too.

 

i would assume stock piston are cast and the cam isnt too great.

 

If stock you have cast pistons and a tiny hydraulic roller cam.
