Transmission Swap Question

[jn66]

Hey Fellas -

Currently have the below.


TCI race tranny , 3 speed,3500 stall
Reverse shift
TCI thunder stick Outlaw shifter
Line lock
Trans brake

matted to



468 blown big block 1098 Hp
Crowler crank
World block and heads
Edelbrock aluminum water pump
Lunati rods n valves
671 Weiand blower
2 x Holley carbs 4150 hp race series

I am curious what other transmissions exist where I could get into a 4th or 5th gear. This is how the car came and am currently shifting gear to gear. Do I have options that allow me to just slide it into 'drive or overdrive' and go?


Thanks in advance.
