Mac Blocks

[Terry Bentley]

MC 8 and Mc 9 blocks are identical. There are several model chainsaw blocks without a removable head that come close, but the integral head is square like later model kart engines. In stock form you would not know the difference on the track. But to modify the chainsaw block would be difficult to add back ports.

I also think, but not positive most if not all of the potential standard saw blocks(100cc) will have ball bearings on both sides of crank. But dont hold me to this.
