pushing the evelope of the 3500

Guess we will find out eh?

smart ass. (Playing with anxieties like that!)

do they not have forged cranks? that and 4 bolt mains, i think it would handle 600 hsp atleast.

I certainly hope so.

I wouldnt normally have my doubts, untill I read a thread some time ago about a guy with 3.1l, 465 rwhp'd chevette that had stretched mains. Im not sure if that was the crossed bolted block or not. He never specified.

as long as all your clearances are good, you run good oil, don't have oil starvation issues and have a good tune it should be fine.

Still waiting on an answer to the question. Too much for 3500 bottom or not?

wow, i hope u enjoy countless days of abusing it! lol
