Stock bottom end LS7 goes 621/534... Graph inside For complete details on the build/previous results check out this post...

After making 595/528 to the tires with CNC ported cylinder heads we upped the ante one more time!!
Adding an RPS Billet Carbon Twin Disc and an ATI 10% underdrive Dampner we netted 621RWHP/534RWTQ!!!! Not too shabby for a stock bottom end LS7!!!

Awesome results. Bet the tune had to be tweaked quite a bit to keep the motor from dying at clutch-in compared to the previous tune. Light flywheels and clutches are great for performance but they can be a bear to tame on the street. Major props to Vengeance on another impressive build.

The tune did require quite a bit of work to get drivability back after taking so much rotating mass off of the engine...
We are very happy with the results so far

My car could definitely use some tweaking here. I'm not going to bother though since I'm about to put a turbo on. The fact that you were able to tune out all the problems with all the work done on that engine is impressive. Well done
