Will it use the LS7 crank bolt or the LS1 crank bolt? Thanks

Does the crank have the long snout that a dry sump, LS7, would have? If so, then use the LS7 bolt. If not, use the LS1 bolt.

My setup was converted to a wet sump and I used part # 234-2504 (ARP SB Chevy Gen III/LS7 8740 Balancer Bolt, M16x2.0 Threads, 1-1/16 Socket, 5.225" UHL.) It is an LS7 bolt but the UHL (under head length) is less than the long snout part #.

Thanks, it's the standard f-body type oil system. Based on your comments, it wouldn't have the longer snout that is normally found on LS7s. I changed my pulley a while back and wondered if I screwed up. I'm thinking of getting an ATI pulley cause of all the stories about harmonics with the longer stroke.

That's why I went with the ATI pulley. I bought the motor and it already had a UDP on it but I changed it out anyways just for peace of mind.
