You could put 180 rods in it and also get a set O-435 angle valve cylinders with Dome top pistons plus a 200 wide lobe helicopter cam but it will be a Avgas or race fuel engine with a 100 plus octane fuel. I built one about 8 years ago and the thing ran like a rat on acid! It was a strong little motor
