Nice Build...The sb2 looks right at home in the GN. Love the Geardrive and the Exhaust. Nothing sounds better than a Geardriven car in the water box. Should be interesting to see how fast this thing goes. Patrick Barnhill went 7.70's with his Geardriven sb2 combination with a blow-thru set-up...
Good Luck running with the boys in the 275 class. That class has really taken off over the last couple years...
Looks like you'll be right in the mix...
