I have had jets all my life and I love all the info on boats and motors. I want to build a circle boat and possibly run it in some races. If I run a blown motor does it have to be on alcohol to race? I have some parts to get the projest going but I am not sure if I am building a motor that will compete. I also need a boat. I have a 4 bolt chevy block that is 60 over and a scat crankshaft. I have not baught rods or pistons yet. I have a littlefield 14-71 blower. Any info would be great.
