Re: gas to diesel conversion

Those of you interested in the 6.2L/6.5L family might like to see this website:

http://www.optimizer6500.com/

As far as what I did to my engine, in a nutshell: lowered the compression by topping the pistons, boring the engine to .040" over, installing 6.5L turbo injectors, having the injection pump rebuilt to 6.5L turbo specs, installing a turbo off a 7.3L Ford diesel, and installing 4" exhaust. With all this work, it pulls about the same as a late 90's Powerstroke diesel, which I think is pretty good.

Here's a thread following some of my build-up:

Looks like I never really finished up the story, though. I'll have to write that later.

Also, www.thedieselpage.com is a great resource for GM diesels and conversions.

The engine from that van would work just fine, but the other accessories like the radiator and brakes will be different than the truck. You might be better off finding a truck in your body style so you can get all the other stuff you need.
