time to buy converter and gears

[taco502001]

Well I have finally done my research and with my cars setup i am looking to install a new converter and 4:10 gears. After talking to scott brown and scott marrison I am looking at a 9.5" 4k stall from ptc and going with richmond 4:10s and rebuilding the rear end. They have both assured me that with what car has should run 11s easily. If you guys have input on other converters and gear setups to go along with car setup let me know

Cars Specs:
71 dodge demon bone stock as far as interior and any weight reduction is concerned

440+6 Block out of 70 challenger
