You might want to consider a vortec 4200 - if you can find a complete 2wd trailblazer thats been bent in half - you can use the engine and trans + its MPEFI from the factory - 275 or 290 HP inline 6. Locally at the u pull it yard we can get a drop out for ~$700 with the harness, pcm, dressed engine and transmission. In a C10 driven normally you'll get ~24 mpg highway. The extras you would need is a rear sump oil pan and a pickup tube out of a 5 cly. colorado. Strip the harness and reprogram the PCM to kill VATS and wire it in.
Engine mounts (home fabricate) and an EFI fuel system round out the extras. 4200 projects + info


You should just post this every time as your sign off info.

Such as this from Beater.
