My stock LS + ARP's lasted about 11000 miles at 300 WHP before it started losing compression. I pulled it this weekend and 3/4 of the ringlands were toast. Perfect tune with hondata. I would dial the boost back a bit from 300 WHP if you drive it all day and drive it hard.
I'm rebuilding the motor with a ported head, wiseco pistons, eagle rods, bigass cams, and a GSR tranny
