I've run BioD in mine and it was super quiet.

The thing to check with this engine, however is the power curve - I believe they produce most of their torque in the upper range of the curve (around 2800-3000 rpms) - good for highway cruising but the low end grunt may suffer as a result. Again, super engines - just not sure about putting it in a crawler.

Good luck -
James, thanks for the info!! I was curious about the power curve, I think with the low end gearing I will be ok. How is the idle on the OM617? just thinking if I have to start in gear (low/low) on a hill, my 350 will start just fine but there is a surge as the IAC (idle air control) kicks in for the idle and you need to be ready for it. Thanks again for the response..
