How can you tell the difference between the 331 & 354 from the picture? These motors also came with solid lifters & adjustable rockers. That's how I obtained one of my sets too. I sold the marine valve covers for the same amount I bought the whole motor for.

Sodium cooled valves and exhaust rotaters were very common in gasoline truck engines. The engines were worked much harder than in a car and this made the exhaust valves last longer without burning. The same concept applied to marine engines.

I don't think they built the 354 with anything but single or dual 4bbl carbs. The two singles were common on the 331.

That's not true. According to what has been published about them, the numbers on the marine blocks were
In fact, my marine 354 originally came with a 2x1 manifold on it, and the tug boat it came out of had 2 motors; one right, and one left. Both were configured the same, except for the rotation direction.

Same as Powerflite. My engines were Marine APV motors. left and right. one 331 and one 354, a replacement motor, to the original it seems. but both had 2 x 1bbl carbs.
