Black Betty Posted August 28 Report Share Posted August 28 is it true that the 3500 durability is better than the 3400 especially the piston slap issue that would arise in the 3400 Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted September 11 Report Share Posted September 11 (edited) Yes... leaps and bounds better than the 3400.. However, its not a direct swap. But it is doable if you have mechanical know how, and can read the swap guide provided by Milzy Motorsports. https://www.milzymotorsports.com/3500-swap/ I was contemplating doing this swap on my 2001 Pontiac Aztek if the Head Gasket blew, or the engine blew. It never died, and is still running today. Now that I sold it, I aint worried about it at all!
