You can gain maybe a little. But to really make power. Have to turn it 7000 rpm. Or make it 450 or so cubic inch.

4" x 6" makes 415cu. There is a lot of small (honda) big end rods out there for small block Chevys and Fords. Some a little bigger than 4" I have used cheap smog pistons in a AC. Had to cut the dish out round. Cut a dowell rod same size as main bearings. Then cut another one to fit inside your honda big end. Cut a 1/8 x 1" flat iron 3" long. See how much you have to grind to get it to turn. Don't forget the cam. I've seen some pretty radical cuts on cams. On my AC I've ground on rods and the cam. Plus ground block 12 times. Cc your combustion chamber, so you know pin height and rod length. Or go to a tractor puller engine builder. I've worked 3 yrs on my D17 and Had engine out 3 times and getting ready to do it again.
