meca Posted October 27, 2012 Share Posted October 27, 2012 Hello all, I'm new on this and have a question, I'm looking to have my engine rebuilt soon I have a 2001 vision cx613 I believe a 430 hp but has been turned up to460.When it gets rebuilt can I make the displacement bigger for more hp? I pull 42 ton and would like a little bit more power, any suggestions on the best course of action and where to get the parts from?

oilburner Posted October 27, 2012 Share Posted October 27, 2012 Yea like mack mhe9 said you my be able to get some aftermarket parts to beef it up but i have never heard of big bore or stroker kits for the macks, but some turbo and fuel system up grades can help and you could do some software upgrades on the ecm. good luck Quote Link to comment https://www.bigmacktrucks.com/topic/28020-engine-rebuild/#findComment-143311 Share on other sites More sharing options...
staxx Posted October 27, 2012 Share Posted October 27, 2012 Not alot you can do if its already a 460 , if you had to have more hp I would go with bigger injectors and turbo upgrades are possiable but then you need to be careful with high exhaust gas temps . If you had unlimited funds Iam sure we could go bigger bores etc. monster motor but this would basically be a race engine . So if you unlimited funds lets get together and I will help you spend your money. What gears and trans are you running do you have a trans cooler ?

staxx Posted November 9, 2012 Share Posted November 9, 2012 Scrap the crud off the tag on the rear and see what ratio it has have local mack parts or service dept run your vin and see what it come with from factory is another option.
