I look at the two like old school verses new school. Keating runs what you said and a clutch, heck he even ditched the water to air cooler for a high pressure water injection system. Greg uses new school, N2O, water/meth and a converter.
Greg needs several converters to test ( this was his first outing) and Keating needs a chassis guy... ... either of these trucks should be in the low 8's if not 7's..... just an opinion.
