I am toying with the Idea of doing a Cummins Conversion on My 03 Chevy Trailblazer and like the Idea of the 3. 9 ISB 4cyl Diesel. The Trailblazer has the 4. 2 6cyl now so this should not be that hard. What transmission will fit behind this engine? I know I will have to beef up the front suspension as the Diesel is heavier. Where can I find a good Cummins Engine like this? All info will be appreciated.
