converting c15 to c16

A 1mm is 70 pin.

 

C-15, C-16, C-18 are the same block. Now to get the right pistons, liners and rods for your crank is very important.

 

Dude do you not check the threads you start? http://www.thetruckersreport.com/tr...ucks-eighteen-wheelers/244585-c15-to-c16.html

 

Why? Whats the benifit? Is there going to be that much differrnce, other then some nore weight and bragging rights?

 

The weight would be negligible. If you are at the point of a rebuild, and have non core able parts, it would not be much of a price difference. An you get to have a real 15L. And those that need extra power for heavy loads.

 

The C-16 crankshaft will drop in a 6NZ C-15 block.

The advantage of the C-16 parts will be torque. The extra 50 Hp and 200 lb-ft of torque is extremely noticeable between a 550Hp C-15. There is no weight difference between these two engines in the same truck. Usually the weight difference between a C-15 and C-16 powered truck is in the rear axle assemblies. You couldn't spec a C-16 truck with standard DS404 40K lb rears. You either had to chose High Performance 40K Lb, Super 40s, or 46K lb rears. The HP 40s added an additional 225lbs to the truck. The Super 40s added 600lbs to the truck and the 46K lbs rears added roughly 825 lbs to the truck. The reason was the added torque put too much stress on the ring and pinion and caused a high failure rate, Eaton wouldn't warranty the rears if these heavier rears were not speced with a 600 Hp engine. The HP 40K lbs rears had to be used in an environment where there was very little stop and go traffic before Eaton would warranty them, so these were installed only in over the road trucks. The Super 40s were installed in 600 powered trucks in a regional application where more stops were encountered in a days work. The 46K rears were mostly in vocational applications with 600 hp engines, but the first two years of the 600 engine option this was the only rear axle assembly that was warrantied by Eaton for use with a 600 Hp engine that was available, so all early 600(1998 & early 1999) trucks will have 46K lb rears


You will need someone to flash a C-16 file to be a true 600 Hp and 2050 lb-ft engine. The problem with that is the fact the engine block will have a 6NZ serial number stamped in it, along with the ECM having the engine serial number programmed in it. A CAT dealer will have a hard time getting the factory passwords from CAT to make the proper ECM changes to convert this engine to a true C-16, since there is no engine serial number to match what you're doing in CAT records. The only way you may possibly do this with CAT authorization is to have a certified CAT rebuild facility do an out of frame on the engine while converting it and sell it under a reman serial number for a C-16. I'm not sure even that is possible either.

 

I am thinking of building a "rat-rod" out of an old 3406E i have in the shop, what would be the best engine parts combination to get lots of power? This is something i want to build over time.

 

On ebay there is a CAT C-15 600 hp. ecm for sale. Buy it now is $750.
