Those air fuel ratios on your dyno sheet, are those valid numbers ?
I would certainly hope not. Good catch!

Exactly but i have had several people inquire about having motors re-dynoed on my dyno that were very unhappy about how much tuning was done while there motor was on dyno, wasnt implying thats what happened with yours by any means. I beened rushed off dyno before i had mine before, i wasnt thrilled!

Im not done yet lol, if i cant make 700 observed hp im adding stroke, bore and compression. My goal is to take my scarab from mid 80s to mid 90s or faster. My hull being smaller than 5050s will take less hp to run there but i also own two short deck blocks so i wont be reaching his hp nimbers either!

What did you use to mount the coils to the valve covers - Or did you make something up?
I am running the dual sinc distributor from Holley with an MSD box.
I have access to a laser, so I fabbed up my own brackets. Eliminating that MSD box and letting the Holley control smart coils certainly takes a lot of the variables out. Make sure you get good plug wires! Are you running a crank trigger? (So the dual sync is only using the cam signal?)

im not done yet. Engine builder is busy so we pulled mine off so he can get 2 more engines dynoed and another engine built. Should've bought profiler intakes, pulling dart intake off and head porter is going remove/rework the cloverleaf intake. Best pull was 840hp torque like a diesel. See if I can scrub another 25 out of it. New power is a drug addiction! I'm pretty confident 93/95. Would like to see click or two under century mark. Give some of my cig friends a run for there money

Sniper Jr or Sniper?

Off topic, but I was at profilers booth admiring their cnc heads and intakes last month. Started talking with their guy. Mentioned how I'm into the marine stuff. He said "That head you're looking at is our 375cc, for marine NA 572, I would recommend the 355 version. Not just for port volume, but this 375 comes with a 55 degree valve job, and that just won't last in a marine engine".

Its nice to see these guys who actually know their product, and its intended purposes.

Any pictures?
How much to make another set?
I don't have a crank trigger - That is why I bought the dual sinc Distributor.
