I am fairly new to boating and purchased a 1985 22 Nordic Daycruiser. I wanted something to handle the parker chop, my friend already has a pretty insane alcohol flat for go fast fun. However, I gps'd it on Mojave and it ran 55.6 mph. I am not expecting much more out of it with the pretty stock 454 BBC and dominator w/ a droop. I would like to get the most out of it without throwing good money after bad. I am planning on freshening up the jet and adding a place diverter before the start of the season and a friend of mine might have some thru transom headers at a good price, is there anything else you recommend to make it the best it could be while still staying true to the cruiser purpose it has. 65 mph is my lofty goal.
