But shouldn't you build your combination around what you run and more cubic inches can't be a bad thing???????

Re: Overbore and intake valve size
yes most definitely,it was just a thought. If you went from 030 to 060 and car slowed down with no other changes could intake actually slow it down in this case?

Re: Overbore and intake valve size
In addition to more cubic inches, it will unshroud the valves and chamber which it is a plus for engine flow.

Re: Overbore and intake valve size
Thinking out loud....the extra weight of the piston is of any concern? The cylinder fills to capacity regardless of any restrictions(valve size, head design)?

Everything helps on a small motor, but make sure you concentrate on minimizing the deck height.
