    duramax is different breed from a mechanical cummins 4bt. duramax's are common rail and run electronic injectors that can be held open at different intervals/durations. 4bt's timing is linear in that it is fixed and uses mechanically timed injections of fuel and a poppet style mechanical injector. can't compare the two except that they both use diesel fuel.

    I don't believe you could make a cummins whatever run as smooth as a SBC. If you can, you are not very good at tuning the SBC...

    Thunderbird will do just fine.

    Agreed. I have been around enough 6bt's to draw the conclusion that they are noisy and vibrate more than any tuned gasser I've seen. The 6.2 in pigpen vibrates more though but it has poly spring bushing motor mounts.

    More fuel and boost will smooth out that little guy.

    Smartass. I still think it has a cylinder with low compression. Is it possible for the compression to be low enough in one cylinder where it doesnt fire at idle but it does when you give it just a little bit of skinny pedal? Cause pigpens mota vibrates REALLY bad at idle but smooths out perfectly above idle.

    Hey if you're still trying to find one of these, there is what looks to be an old frito-lay truck for sale out on Merka Road south of the winery.

    so after jamming the cell phone in my helmet and trying to get voice guided directions by eric I never found it on Merka. However on my way home I took a different route and cruised right by the thing on Old reliance road.

    Too bad it's a 350. It did have a kick ass kitchen in it though.

    There is a old IH pickup right next to it with a full floating axle if anyone is interested.
