Hey all,

Could I use a atc110 head on a atc125m engine to boost compression? Or is the combustion chamber identical?

Completely different motors. Heads won’t interchange .

Are you thinking of the vertical 125? I'm talking about the horizontal 125. Always thought there were only the most minor of differences between the 125 and 110 engines.

Nope the horizontal motors just look similar but nothing is interchangeable . Like I said their completely different .
The 110 actually has larger ports and breathes better and will make more HP when souped up :)
