I tossed the MP one into my 360 build some 10 yrs ago. After 10 summers of occasional use, so 10K of the typical weekend driving, I recently tore the motor down as I started to build the W2 stroker replacement.

My combination was using the Sealed Power 220-3103 chain, which is a double roller.

Anyways, off everything went, no wear, no problem. The chain was on pretty tight after all these years, and I have always found my ignition timing to be absolutely solid, no jumping around, etc.

I will be putting the very same tensioner back on my stoker...although I've always wondered if I should be tossing the crank oil slinger into that mix???
