Pistons and rods for Whipple H.O. kit
 

i just bought the whipple H.O. kit and im wondering if i should build the bottoom at the same time of the install. What compression pistons would be good? Can the stock motor take 10ibs of boost without problems? Thanks

if u have the money i would deffinately do a forged rotating assembly, it would be better in the long run... i hate to tell u but eventually your stock bottom end will blow out...the stock bottom end can take 10#'s but i'm not sure for how long.

Well most of these kits are made to do 8-12 PSI on the stock bottom end.
Why fix what isnt broken? I haven't had any issues at 11 PSI myself.
If you want to go 15 PSI then by all means get forged parts.
