Wildfire and RLW the boat mesures 24ft 6in up the center line not including the drive.I have a 1988 454 Mag engine .030 over,heads rec port with a mild port (bowl and blend) Has comp cam roller tip rockers,valve springs and cam .565lift forgot duration but could find out.kept compression at 8.75-1 to be blown BM420 later (no money now) I run a TRS outdrive with a reworked 23p to 24p quiclsilver prop.I have tried Mirage 23p but acell is slower as is top end.It runs a true 62GPS.but porpouses at 30 on up in calm water unless you add tabs.My personal feeling is if you have a small block you wont have the torque to push the beast.I would like to find an external steering system cause there is slight chine walk at WOT.Note there is no porpous or chine walk in 3 to4 footers .You are right about Jan Hot boat my wife mailed it in December and was a cool Xmas pressent Hard to beleive 3 weeks to print.As I do any more upgrades and changes I will keep you poasted...
