how does he know the crank is bent?

unless he has sent it to a machine shop?

My last crank i had ground was slightly bent and the machine shop ground it and said it would be ok, so i used it was fine putting out over 400 bhp and is still going strong now,

so might be worth getting it checked, if not send it to me and i'll get my place to check it?

Well you know the shells we gone so the only thing you werent expecting is the rod and the crank but if the crank turns out ok its just a rod which aint a probelm
