Parts needed to hop-up a Cummins Big Cam

Nope, just an idiot who over heated it before I bought the truck.

 

hey davo your engine by the sounds of it should be a big cam 4 with cpl 905 if it is the 320 hp which is not an stc engine like the 444, you will need to change pistons for compression ratio, fuel pump turbo , ###### cam timing but are best off replacing cam to a high lift for the hp you are looking for.

I need your advice on my Cummins fuel pump and I hear your the best SmokinCat

 

Let's talk Cummins I need your help

 

Pretty simple, find a reputable shop and tell them what you want.

Call it what you want but I am very weary of giving people the know how to change a pump blindly and then thinking that I told them to do something wrong.

I'd rather see someone go up in flow on injectors and never touch the pump at first, cranking the pump is hard on cams.

 

Sorry just seen this....
I agree with @SmokinCAT , he is correct. Adding fuel pressure to the injectors adds pressure to the cam lobes, only a matter of time till the Hardmetal starts flaking off the lobes.

Bigger injectors will help, without adding pressure to the cam lobes.
