Just out of curiosity what did you race that cummins with?

32 Chevy with a 572. I ran a 9.6 and he ran a 9.4 with his coolant acting as water injection. :W


My point with the head bolt deal was this: I have never seen a diesel with 4 head bolts last. Some others may know of one but I don't. They all had head sealing issues even bone stock. That's why Ford got away from the stupid 6.0/6.4 four bolt design when they went with their own engine design. "Ford" got it right this time "with this issue". No sealing issues with their 6.7 at all. In all fairness, same goes for the other two. Funny when they go to a more than 4 bolt design the sealing issues go away.

Will this engine be the one that breaks the rule? I don't know? Cummins has a dam good design team but even the best make mistakes and cut too many corners sometimes.

I'm also not a big fan of chains to drive things after seeing what happen to my 6.5 chain. It was junk, and I do mean JUNK at 130K. And this is a heavy OEM chain. Look what is happing to the Ecoboost timing chains. Again, more problems with stupid chains and this is with a super light duty engine let alone a big diesel engine with heavy valves and high valve spring pressure.

Can Cummins design around these issues? I sure hope, so but there is no way in hell I would be a test monkey on a 50 grand bet on the table. There is a lot of gamblers with a lot of money on this forum. I'm not one of them. :)
