Houston do we have a problem?

Id a compression test on my LS1, all where in the 175 psi rango except for #7 which was at 150psi.
Is this too much of a difference from the other 7 cylinders?
Thanks

Its a lot, I can tell you this much I would do a leak down test and scope that cylinder. Number 7 is notorious from broken ring lands and pistons because it runs hot.
