I have a 90 GT it weighs 3180 w/out driver. It has a cobra intake, 65mm TB, 73mm mafs, compucam 530/540 316/220@.050, BBK shorty headers, aeromotive afpr, 19#injectors, underdrives, no A/C or smog pump. The suspention consists of Mac upper and lower arms, subframe conn., 50/50 rear shocks and no front sway bar. The car also has 4.10's with a fms driveshaft. The best it went last year was a 13.60@ 102mph with a 2.16 60ft time. It had a stock aod and converter in it so it would bog with my drag radials. What size converter do you guys recommend for this combo?? What actuall rpm should it footbrake to?? and how high should it flash?? I was thinking about a B&M holeshot 3000 because I don't want to spend a lot!!
