I just brought a 1974 Dodge Ramcharger. Im swapping in 6BT and 4 speed 47RH transmission and 35" tires. Im going to turn down the starwheel 2.5 turns and denny T fuel pin and intake and injectors and turn up the pump and screw mod and 24 valve turbo. Do yall think my stock 9 1/4" rearend will hold up for alittle while. What kind of mpg will I get and how much hp&tq will I have? All the help I can get would be great. Thanks

 

The rear will be fine if you fold the floormat and shove it under the go pedal.
