I just want a little more horsepower out of them, without making them run WOT all the time. I think more compression is the key to that. They have something like a 5 to 1 compression ratio. I really don't want to spin them over 5 grand. I just want to get a couple more inches of pitch and go fast and look good. This is basically a show-boat. Speaking of shows, anybody from this group going to Muscatine? www.muscatineboatshow.com.
