Here are the build specs:
Brodix Race Rite Rect port alum heads
Stock 454mag gm aluminum intake
Marine Kinetics custom cam: 613in, 598ex on 114 LSA with 4-7, 2-3 swap
Let me know what else is needed to know.

I noticed that too. That's going to put a lot of strain on the distributor gear.
I would think that you are losing a lot of your power with those old school manifolds. A set of Air Gaps or Dart / Victor Jr single planes would probably wake them up to the tune of 15-20 HP, especially with those heads.

I don't see where you listed the displacement of the engines.
Also, post up the list numbers from those carbs. Wondering if they are really HP500 carbs, or even 800's. If they are, and there are no provisions for a PV on the primary side, then someone has definitely fucqed with them.

My oil pressure was over 100psi on the dyno. However, I was not running thru the remote filter/lines and the oil was a little cold yet. In the boat I see about 75-80psi running, 50ish at idle. My oil pump was shimmed for a little more pressure. Prior to me going thru the engines, I only had about 50psi max with the old setup. Not enough psi at 5800-6000rpm imo. Pulled distributor gears this winter, gears still look new after 2 seasons on them.
I think Eddie Young runs similar pressure in his engines with no issues I know of.

Just got back from movies.
460 and 467 are the displacements. Oil pressures in boat now are 85-90 running and idle around 70. Even before rebuild the oil pressures were high but without issues for the time I've had the boat. I'll get to the boat in the morning before work to get the carb list numbers.
I'm using the th 4 ignition so until it's set at 8 and total is 32. I have a new digital timing light coming so to recheck it all. Going to get new jets tomorrow to prepare for weekend. So 92 squared should be what I start with?
