HTM Racing. My wife and I are already sold on the open bow SR-24. My question (like everyone else's) is with regard to power options. I thought I wanted the 496 HO with one of the new blower options and then I took a ride in a new SR with a built 573 and it was sweet! Do you have any performance expectations such as what I could expect from a 454 on up to a blown naturally aspirated plant? Do you have anything on paper or is it best to contact your sales dept? I just got your video, but it didn't really address these areas.
