Response to An update, possibly sad? |
| Most SBC have chain drive cam. If it is a 2 drive gear setup, it would be obvious it was a counter-rotator. Why does it need to be counter-rotating? does the crank have the marks on the rear main seal reversed? When rebuilding a counter-rotator, the pistons should be installed 180 degrees from standard to compensate for the piston pin offset. |
