Run a 605" that's been built for nitrous , running 3:55 gears & 60fts are a nightmare (1.5 no gas) , charger weighs 4150lb without driver , just fitted some 4:10 gears & wondering what it might pick up , got a 10" covertor which stalls @ 4500 , 29" tyres , motor is 9.5:1 cr , any of you guys gone fron 3.55s to 4,10s? ,this snail goes over the 1/4 around 5500rpm.

TIA.
