My case is done at Ollies and being shipped to my builder however the cylinders and pistons are still a question mark due to some flaking issues on a couple of the cylinder walls and wear on the pistons. If I need new cylinders/pistons does it make sense to go to a 3.8 size? There would be no other changes to the engine since my heads and valves and everything else is done and ready to be assembled.

Is the power increase justified or negligible with just the cylinder/piston upsize?

Thanks
