The engine runs good,works good I am wanting to up the Hp so was thinking higher compression,head and cam work, custom intake would bring up the Hp.I was told by a guy that works on these engines that it would be a very small difference.

Have you ever dyno d what you have now and seen where the hp/tq were in the rpm bands? That would also be an opportunity to tune the engine as well, we ve picked up 5 hp on tractors with a slight timing adjustment and some carb tweaking.

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.

There is very little room inside a G262,I have heard some go to 5.25 stoke but not reliable.I will go with the build I have planned and hopefully be more reliable.

I have read that Mike Lepard makes custom pistons for these engines, hope he still is been thinking about getting some myself. An old post on here listed his phone # as 716-308-5987 and email is snappytractor66@yahoo.com. Let us know what you find out.
