The old Crusader manifolds are a consideration for the SBC motor. They're taller, have the water dumps all the way back, angled out and will also give you a performance gain. Should be the same width as the merc manifold- maybe slightly narrower. if you have the room, you can use spacers from 3/4" plate to allow you valve cover access. If not, you'll need 2-piece units. Someone used to make jacketed stainless tails for them that blocked the water exits at the rear flange. These were a class-legal upgrade for P class way back when.

I wouldn't do anything until I knew for certain what was in the motors.

I had 350s in a boat once that did the same thing.I spent months trying to figure it out.The last time around I installed manley stainless valves.I also found that one side of my carb was stuck closed.The float was up with no gas.This was my problem,id hit a wave and the float would bounce up and stick causing a lean condition and tulipping the valves.The carbs were edlebrocks and the floats would slide up and down 2 rods if I remember correctly.The flaost were getting stuck on the rods and staying closed.I put demons on and never had a problem again!

Get another v-6 module, you'll be much happier with the timing curve.

Biggest problem you might have is the motor has to be perfect so you dont have any starting issues with 20 degrees initial timing. Some motors after they are warm dont like to start up very easy with that much initial. Do you have any MSD ignition or Crane ignition boxes?

I think Strip Poker 388 in closer to the problem than you might think. The gas out there today has a lot of alcohol in it and not the best for playing on the water or at the track. You should definately try to use 89 to 93 if you can. It is a mind set that it cost too much. If you bought 20 gallons and spent an extra $. 1.00 a gallon it is only 20 bucks. How much was the engine work? Take a little from all the suggestions and I think you just might be ok. That is my suggestions anyway. Good Luck.
