Been doing alot of reading and learning alot about porting.I am starting to understand how it works. I have a old 372 jug i am going to do first to see how i do. I have two questions i want to ask! THIS IS ALONG WAY DOWN THE ROAD I KNOW. First thing i would like to know is what is the best fuel to run. 87 octane, racing fuel or hobby fuel. Second, i have read on this site that if you decrease the size of your crank case you will get more power. How is that done! Once again thanks for all of your comments!
