I have always gone with my gut feeling about things. There's something about this lump of iron that feels like it may have been assembled with some unskilled labor. From the ad.... "Bus conversion done by myself and a bus mechanic friend" The part done by the owner looks absolutely first rate. The rest which is the engine, well... It did make it to 35mph after about 20 seconds pedal to the pergo! (noticeable knock sound at idle too)I have the room to pull the engine but honestly, not the knowledge to go much further. From reading, I need to build a engine dolly/cradle if I were to attempt this.
