Yeah around here it is LS or go home
. No love for the boat anchor big blocks. Well I guess Todd is the exception HA.
With the 700 ft lb rating I think it would be fine except for extreme builds and/or one too many trips to the strip with sticky tires.
I also considered the TKO 600 but the RS600 from Keisler sounds good at the moment. Too early to get much "real world" feedback yet but I like the concept. Good bit more money than the TKO though if you don't already have a bellhousing, etc that you can use.
