Kinda feel its not all converter related. 400lbs lighter & more suspension adjustability on a stiffer chassis, im thinking i should be averaging 1.25 60's. I'm just NA with a respectable 800 HP+/- & Im wanting to run 8's. We've run a few 9.0s, a gain on my 60s should see the 8s im looking for. At 10 sec streetcar n 8 sec racecar, living the dream???lol
