I am interested in a GMC 2500HD (4X4) SLT shortbed with a Duramax.


I am clueless when it comes to mechanics..... So a little help would be appreciated.....


Has anyone heard of any problems with the aluminum heads and cast iron blocks ?


I was told this may cause a problem when the engine runs hot..


I will be towing a trailered boat with a total weight of approximately 9500-10,000 lbs.


Should I go with the 4.10 rear end or the 3.73. Also, what would be the difference in gas mileage between them both?


Paul....

My understanding is that if you go with the Duramax / Allison transmission combo you are limited to the 3.73 combo. Maybe one of the experts on here can help... I don't think you can get the 4.10s from the factory... yet.

There are not issues with the heads on the Duramax. Edited by: BIGMoe

I just found out it only comes with a 3.73, at least in California.


As for having problems with the heads?????


I just read that it may have problems with the heads since it's aluminum.......


I was just wondering if any of you guys have encountered this possible problem?

You must have heard the "head problem" from a dodge driver http://www.dieselplace.com/forum/smileys/HiHi.gif When I was researching which diesel to buy, I read that on some Dodge majority boards.

LOL!!!


As a matter of fact it may have been a Ford or Dodge finatic......


Actually it was a gas motor chevy owner........

Wrong...http://www.dieselplace.com/forum/smileys/Confused.gif


Dmax = 3.73; Only gassers can get the 4.10's, end of story...
