Competition 12valve Block question

[RyanB]

I have a question for you all about my 1996 12valve block. I sent the engine down to Haisley's to have ot built up. The engine has a build date of 12/07/1995 if that makes a difference and Im not sure about when the block was cast!



Anyway, Van called me up today that while tearing down my engine he noticed that my engine is an International Harvester casting. Anyone ever heard of it? He said that they are very rare in a 12valve block but do show up. He said they were cast in Indianapolis, IN instead of Brazil. He told me that these blocks have the highest nickle content in all of the Cummins blocks making them ideal for a preformance engine but come with one draw back. Above the lifter bores there is a chance of imperfections from the sand casting that could cause water leaks but its rare. He said he is going to have my block presure tested just to double check that its okay!



He also told me that my crank and rods are made in brazil which are the better forgings than the USA made ones!



Does anyone know anything about these blocks? he had a name for them but forgot to write it down.



Thanks... Ryan

How can I find out if my block is a IH? Did your mechanic tell you how he found that out? My motor build date is 02-21-96. Thanks.

THe block will have the international/ navistar logo cast into the block.

Thanks Josh, if you are looking directly at the motor what side would that logo be on? Thanks, Andy.

THe block will have the international/ navistar logo cast into the block.

Indianapolis, Indiana home of International/Navistar - Ford engine, just more proof that Ford owns Cummings!!!:-laf:-laf

Van told me he didn't notice that it was an IH block until he had the timing cover off... said under that is where you will see the IH emblem or navistar emblem.



My real question though is what makes these blocks so rare and special... why do few show up?

The symbol is located behind the cam gear. There is also one on the head as well.

I have a 97 block that I am building up for my drag truck and noticed that it had a IH symbol behind the cam gear also. This block is also the storm block with the dual drain holes in the side of the block for the twin turbo's. Is there a Differance between the Brazil Rods and the Rods built in England I have both. One set from the 12V (Brazil)and the other from a 24V (England). Which set would be better?



Cool conversion you got going there Ryan B. Like to see some pics when you are done.



Thanks

I know Fletcher has a few in his shop.

He said something about getting them out of a Hyster Fork lift?
