Other posts speak of Honda rods ( I haven't read through them lately. ) , I had thought these were worth a look even though quench is lost. From what I recall, the M104 doesn't have much quench anyway so what ever is lost might not mater much. The Turbo Technics conversions allegedly used shortened stock M104 rods.

There is a multi stage approach to what I'm doing. Build a slightly turned up motor, work it out in a test mule then drop it into the good car. Build a stronger motor for the test mule for track days.

I'm not tied to any specific type of build yet other than the good car mods need to be reversable ( RE car body isn't hacked up ) I'm somewhat resistant to supercharging only from a packaging stand point for the good car motor. To throw more into the mix, I have a 97 C36 ME 2.1 engine computer and a long stroke crank from a 350 diesel so with the addition of a reground cam I could make a pseudo AMG motor for the good car.



The good car: 97 SL320 with M104 ME2.1 722.6. It really needs more low end zip to make up for small displacement as the motor really doesn't do much below 3,000 RPM.

The test mule: 92 300SL that is currently motor and trans less.
