Jim - The dohc quits making power around 6500 rpm but will rev a lot higher since it doesn't have those pesky rockers flying around. My car will definitely be at Daytona but I may not be because we're moving into a new building the week before soooo any help you can offer would be GREATLY appreciated!!! Seems like we have a bunch of new SX guys in our area - we all gotta hook up at the races!
