My 1999 ran 75-76 mph with the Innovation 500EFI. Had the heads rebuilt and ported by Veleko and it then ran 77-78 with an all time best of 79.6. I am guessing the freshening and porting added 30 hp or so.

Is that the one on the you tube videos? If so what a sweet running boat!

406ci SBC with TRS and 19P Mirage 68-70 in near glass like conditions. Only made it to Lake Michigan once last year in 2-4 footers and was hanging on versus looking at gps on my phone haha. I've heard from previous owner mid to high 70's in chop.

It's been a long winter but yes I would say it is spinning 6200-6500. There's nothing oem left on this 406. Just had a rebuild last winter and the guy did an awesome job. It runs perfect! I forgot to mention in original post its around 500hp maybe a bit more. Never had it dynoed but with the parts/ specs its a good estimate. It was originally a small block boat rigged at TNT Marine with a 400 small block from United Racing Engines I believe. Original motor is no longer in the boat. It met its demise years ago.
