Mr. T. Minnesota said: (quoted from post at 03:31:36 12/14/12) Forum Members,

Thanks for the info. Reason for the question is the 8N I purchased this summer had been newly overhauled. The seller said he had added special pistons, shaved the head and decked the block. He said the compression "may be an 8:1 ratio" ?? Even as a novice to mechanics the math just did not seem to work out. There is only so much space to work with.

With that being said, the 8N seems to be a lot more powerful than my not so worn out 2N. Had to change the 33 to a 243 carb to make it run right which may also add to the power.

Again, any other thoughts are appreciated. In retirement my goal is to learn something every day.

My guess if you save the head and deck the block its possible to gain a pony are 2....
No guess the difference in a 2N and a 8N engine is the head that's it,,, the difference is in the valve pockets... Put a 2N head on a Very good running 8N and the power lose very noticeable.. A 8N head is very close to the Hot Rod aluminum head that was offered for a N... You can shave a N head all you want to the valves will never hit ( write that down )... The piston is a different story but can be over come... A """"NEW"""" reproduction head has the same valve pockets as a 2N head and will cost you a pony are 2 so don't go their.....
If you are power hungry bump the RPM up if you can hang on Theirs 40 of'em their waiting to be turned loose :lol:
