How about substituting an Isuzu 4 or 6 cylinder Turbo/Diesel in a similar vehicle and showing us the problems encountered, in addition to the advantages and disadvantages, of putting a GOOD Oil burner in a modern vehicle, like a Tahoe or Silverado?

I am anxous to go read 3-4-and 5. Good job you guys. I don't know you, vice-versa- but I am proud of you. Digital camers are useful in projects, like I photographed the electrical circuts in my wood shop walls before the were covered up. Now I'm ramblng, again thanks for sharing your story.

After discussions with GM engineers, we believe that the stock transmission (a 4L60E) and 4WD driveline can handle the new power. We are, however, currently installing an aftermarket transmission controller which'll allow us to move the shift points -- and install paddle shifters. Lorenzo: Thanks! Erick: It idled ok before the computer upgrade, but didn't like to receive any strong throttle inputs. The new fuel map improved things significantly. We're in Texas, so we're not intimately familiar with CA legislation. The H.O. 350 isn't CARB certified, so if they discovered the different engine, you'd be in trouble. That said, the headers we picked are 50-state legal and would be fine in CA. Also, according to all the documentation we have, this engine -- when coupled with the stock catalytic converter as in our application -- should pass the sniffer test easily. So, it does beg the question how they'd actually *know* that it's a motor with different internals. The block (other than sporting new paint) isn't that different, and certainly isn't different to the untrained eye. Of course, you should do your own research for your specific area before launching into a project like this. ambush27: This was an engine swap, not a drivetrain swap.
