MAC 45 with AA 45 piston/sleeve

[NITROSNIFER]

Has anyone run this combo yet. I have one and the stock liner is in great shape but wonder if the performance is better or the same with the AA 45 liner/piston???

I have run one -- Runs as good as my best Mac P/L --takes a lot of break in time -- almost a gallen of 50 %

You might want to grind on it to attain your Mac port timings -- mine came up short of the Mac

Hope this helps

I'm looking for a little more torque than the mac used to give out. But yes this is the answer I'm looking for. we're at 3400ft so power at times is lacking.
