I have a 455 bored.030 over,quick fuel 750,comp cam shaft i dont no specs off hand motor was built off joe mondello article bullet proof big block the motor is suppose to produce 400hp.Joe recommends 342 gears do any one no what gear came in that car and who sells a 342 ring and pinion.Is anyone running 342 gears ?do you like performance

 

It probably came with 2.56 to 3.08's.

 

Thanks

 

Talk to Jim (Monzaz). I believe there may be 3.55 aftermarket gears for these now.

 

My car pulls real good,do any 1 have 355 gears behind they 455 ,if so did you have to do any other modifications did it make your rear end noisy.Was it a big difference in performance of your vehicle
