Thank you all for the information. I was trying more to understand how all the "pieces parts" work. I used my engine only because I am a little more familiar with it.

Thought I might have been onto something, but not knowing how all the parts worked together I needed to ask.

What I was seeing in my head was something like this:

Stock cylinder/piston/connecting rod creates X amount of compression.
Larger diameter cylinder+stock length rod=more volume=greater amount of compression.
Larger cylinder+shorter connecting rod=same X amount of compression.

I was seeing more volume squeezed into a larger space(created by shorter rods) as being equal in compression to stock volume squeezed into stock space. For lack of knowing the correct term...having the same psi. My line of thought was then if you had more volume (in the bored cylinders) squeezed into the stock space (in the head) using stock (imagined slightly longer) connecting rods it would increase the compression to some extent.

It seems I was a bit off in left field. Oh well. I have to learn somehow.

Thanks to everyone for the info.
