I think you'll need to spin it higher to get everything out of it. 
I spin my LS2 to 7500. Will find out this weekend what the new motor likes. What lifters you running?
Get that thing to the track ASAP.

Over the years I have not seen any evidence to say that piston velocity and side loading etc. warrant us keeping the stroke down. But I'm undecided at this point.
-Rev springs, 1.7 non-adjustable Y/T rockers, Inconel exhaust valves that can take more heat..... 2.05/1.60 valve sizes
-900rwhp is possible not sure I want to turn it up that high without first making some runs. I'd like to end the year on a good note not broken.

what does your valvetrain consist of?
you still have a stock tach, how where you shifting the rossler 210? (that was a rmvb right?) your 4l80e was shifted by the bs3 computer right

It was like an Alley Oop play... I had to finish off the dunk.

LS2- Comp-R lifters, Harland Sharp rockers, Comp dual springs
ERL- Morel lifters, T&D Shaftmounts, and Gold dual springs from TEA.
Still have the stock tach but use a shift light when I run the TH210. BS3 does shift and lockup the 80E.
Back on track. PSJ, from what we have been told the stock style replacement ones from Comp aren't designed for high RPM or really high seat pressure. That combined with high boost could be very bad. I started out with a new set of Comp-R's in the ERL block and they gave me nothing but problems. From the looks of them just after the short time I ran them. I wasn't happy. The cup retainer was distorted and looked like it could possibly pop out. We won't run any Comp lifters again.
