cam/ piston and comp.

[EXDUNER127]

What kind of power difference should you expect between;

Stock bore, 11 2:1 comp, hotcam stg 2

87mm bore, 11 2:1 comp, and hotcam stg 2

is there a noticable diff in power just because of the bore.

and would you need a longer swing arm for this setup to race comp hill. in dunes?

i would like to compare that too. some say no difference and other say you will notice it. i really don't know. i have a feeling that stock bore would want to rev really high. i have a 406 and i have a lot of power above the stock rev limit. the bigger bore you go, the more power you will have at lower rpms and you won't rev it so high.
