W900A kenworth engine swap?

If you are doing this for business as a truck to make money with that would be a bad business decision.
If you enjoy doing that type stuff, have the time and abilities a complete doner truck is the way to go.
Start a page and list each expected repair items and the expected cost. Total them at the bottom and double it.
Got the cash? Go for it! Just my opinion. I have done some but not that one. 3406 is also good.

 

It's not that hard mechanical engine to mechanical engine.. I'm swapping a 12.7 into a short hood w900a.. pulling out the big cam 3 400hp., 13spd rto and radiator assembly..the 12.7 barely fits according to my muesurements but it'll go.. then there's the wiring.. decided to use a complete donor harness and rewire the truck into it.. I'll let you have the big cam and related parts cheap.. need em gone and need the money to start 12.7 overhaul..

 

Also cutting off the 8bag 4.10 rear axles... it's missing a couple air bags and ride controls. I'll give you the rears if you haul them off..

 

The 855 will be a tight fit as there is very little recess in the firewall of detroit powered trucks, I installed a B model cat in a factory 8v92 truck and there are places where there are 1/2" or less of clearance.

 

I could sure use the rears. Where are they located? When can this be done?

 

It's over here in oregon at our yard.. I can cut it off at any weekend.. just noticed your in Tennessee.. shipping them to you would probably cost more than there worth..

 

Stand corrected thought I was responding to the original poster.. and Smokin Cat is right. if the firewall isn't recessed the 855 won't fit.. mine has about a 4" concave in it and the 855 uses up most oh it..
