Bill......in this case was the best!

Dave.......I'm not all knowing (wish I was) about the ins & outs through the years of Hi Perf. motor systems but I know one thing......the founder of Flagship Marine Engine Co. Tom F. put his very
best into this boat. His son told me this was his father's personnel boat and their top engines went into it.......575 cu in chevy tall boys with the Arizona EFI's on top........I'm sure you saw the pictures of the engines and was it obvious that their were Arizona EFI's on them? ........if not, pretty good guess!

Wow, very cool - nice find!

Wishing You All the Best with your Beautiful Mitress. I have owned mine now for 9 years and can not say enough about the Joy it has brought me. They are a fantastic breed of boat and you cannot beat the "Old School" styling. My boat came from Thiuder Row and was picked up by Bob Wallace from Offshore Performance. When I took ownrship of the boat I had Bob build a pair of 540s. I could not be happier with the boat. A wave crusher in NJ Waters and equal to the task in Florida where my wife and I now reside. Once again, Best of Luck and Many Years of Safe and Pleasurable Boating.

Well thank you very much for the kind words!.......pretty excited about splashing her in the ocean!....... Post some pictures of your Mistress!

actually i was building pro street rods in the early 90's and started playing with EFI stuff when you had to build everything yourself. I used lots of ASM stuff back then and remember they were one of the first to come out with a well thought out stand alone system and if memory serves they were out for about a year and then seemed to disappear. A few years later . . . . the 500EFI was born. A friend of mine has 3 complete ASM systems that still have the logo cast into the upper plenum. Their pretty cool knowing the history and a fantastic system whatever variant you have. Looks like one heck of a find. Kind of like an old Yenko Camaro or something :D

If you do a search on Dean Hoskin Cigarette September Fan of the Month you will see my boat in NJ waters near AC..

Dave...........What's really wonderful & crazy about the present power in the Mistress is, I could not appreciate (since I know very little of those big power applications) when somebody said, "Holly jeeeees"
that's top notch race stuff there"......I'll post a picture of the embossed ASM logo on the plenum as soon as I tear off the shrink wrap on the boat.

Thanks I'll do that!
