Find me a bone stock MR side oiler with 10 or 11:1 to compression who is running over 450 HP with completely stock heads. Ain't happening.
Whenever I get around to it, I'll let you know what I dyno at. My build is similar to yours. Although my builder said it should make closer to 500hp and wasn't a BS type of guy. But the dyno will tell.
