Does anyone know what grade of material the 3800 crank is made out of? I'm pretty sure it's not a forged crank, but is it made out of nodular iron. etc. For guys to making 800whp, I would expect the crank to be made out of stronger material than the turbo crank in our turbo Buicks.
 
nodular iron with cross bolted mains , tough enough to go as quick as 8.6 @156 stock block and rotating assembly in a front drive car (ZZP)

GBGN1 answered this question for me in another thread, thanks though. I can probably find an uncut usable one for pretty cheap as well. Although I have ran across of couple of 4.3L ecotec3 6v's for sale, with harness and ECM. Damn, it would be an awesome motor to slap a turbo on and mount in a GN.
