Looking for more horse power

[JMaro4321]

I have a 2001 Mack RD with an E7 motor 350 hp. I just want to know if the pistons and the crank are the same as a 427 hp. Can i change the turbo and the fuel pump to get it up to that horse power or is there more I have to do? Any advice would be helpful. thanks again,  the rolling turtle

Call Rochester Diesel.   I've put his stage 2.5 and stage 3.5 on my trucks.  Definite usable increase in power.  He'll send you a new turbo and necessary rubber fittings to make it fit, and honed out injectors.  He'll want you injectors for cores.    Both trucks I did were E7-400 Macks.  Both drove GREAT afterward!!    Ask for Brad 507.288.8038
