Anybody have any info for the jet sizing on a Mercury SC525 with a dominator (the later versions)? Just want something to reference to.

I've had a few apart and here are my notes on these engine's. Special note is on total timing. Rev engine until timing stops advancing and then set total.
I have found that total is at approx 4200rpm.
454cid
7.5:1 compression
rectangle heads
Holley Dominator 1050 carb - jetted 98 square + 6.5 high flow (not standard one's)power valves front and rear.
177 supercharger
AC Delco MR41T spark plugs - gap .035"
35° Total timing - typically reached at 4200rpm
Premium fuel required. Merc suggests min 92 octane
And following hyd flat tappet cam:
Merc 400 / 420 / 425 / 525SC
