Poor dump trucker

When going from 350 to 460 on any ETECH style engine will at least require turbo and injectors. If it’s the first series of ETECH then the cam key will need to be replaced with a off set keyway or it will overheat in the summer. Also some of the ETECH 350 has a smaller vibration damper on them. Mack made us put the bigger damper on even if we bumped it to 400 HP. The CCRS and ASET series all use the straight cam key way regardless of HP rating. Yours being a 2002 could have either the regular ETECH or the CCRS engine.  One way to tell the difference is regular ETECH has a plastic push on fuel return line coming off either the very front or very back to the cylinder head and goes to the fuel pressure regulator on the RH side of the engine block above the air compressor. I can have my guy pull up the build info and engine type . Just need the last 6 of VIN . Remember the ETECH . CCRS  and ASET engines are just 11 liter engines. Comparing a 400 ETECH to a 400 CAT or Cummins are to wildly different animals. 

The last 6 are 003215. Thank you very much for the reply! Depending on the cost of the turbo and injectors, I would be open to upgrading them.

I have searched the site and internet for a while now and I give up! Lol trying to increase the hp on a e7 350 in my 02 cv713 granite dump truck I have. It does pretty ok but it is definitely falling behind. At the quarry it works at, it misses out on an average of 1 load a day compared to all the other trucks running out of the quarry. Not looking to make a hot rod just want it to be able to run respectably with the 425-475 hp trucks it runs with daily.

a good friend of mine ran several Mack’s in this era of trucks, he said he’s pretty sure the e7 350 can be flashed to 460 without changing any hard parts. That would be great if possible. 
I also have jpro and Vmack but can only get jpro to connect to the truck. Have also been waiting on the dealer for 2 months to get it in to put a 460 file in it and am tired of waiting on them.

any help would be greatly appreciated!
