Default All bore 107

I know rev performance has a bolt on kit. My real question is could i use 4.125 s&s cylinders and a different piston or same.

my plan was to build a 107 all bore with 110 heads.
11.0 compression with s&s 625 cam.

any suggestions?

Not sure what your asking. A 107 uses 3.927” pistons. The 4.125 is for 117 or 124, both require bored out cases.
110 heads have a larger combustion chamber than a 103 and the pistons will have to match in order to build compression.

well a 107 all bore is 4" stroke x 4.125 bore. Yes same as 117. Cases will be bored. I want to keep the 4" stroke.

Try posting this in the engine section. There are some very experienced builders over there who should be able to help you.


I seem to recall somebody (DJL maybe?) was running a similar combo. He might see the post over there and chime in or you can try searching "All Bore 107" and see if the member I'm thinking of pops up.
