Where is your motor happiest? Mine seems to run best between 11.5 and 12, a little richer than other motors are typically run. It would seem they would run better leaner because of the chamber design.

Increasingly I find the difference between a "fact" and an opinion is the number of people who believe it.

Are you talking about the hybrid motor? They do like to run a little rich. You should see the 3500's when I pull them apart, carbon city! -
Yep. Mine already has some buildup, but that's from breaking it in. I'll have to suck some seafoam thorugh it.Increasingly I find the difference between a "fact" and an opinion is the number of people who believe it.

My 3500 was happiest with 26 degrees of advance and around a 12:1 AFR. Quite a few other engines that i've tuned like to be a little closer to 13:1 and 28 degrees (stock cam and SCR).Comment

LOL, the only vehicle capable of traveling there legally is wifey's LH0 GP.... i don't feel like pulling an 18 second timeslip
i imagine there would a few decent places to log a thorough 1st gear or 0-60 run without attracting attention though...Comment

GM obviously didn't think so!
the 94-95 3100 PCMs SHOULD have a cat protect function in them, and richens up the AFR even more depending on how long you've been in PE mode...Comment
