The Daytona's , at least the earlier ones had a much wider center pod and had a tendancy to kick the tail on the big end and building in the reliefs would help with that. All I can tell you about the weight is that I was pleasantly surprised. Most all of the ones that we have worked on in the past have had 800 or more HP and I can only attest that they work well. I did have a heavier lake version a few years ago that we did extensive work on the bottom of and it worked pretty well with just under 800 HP.
