Knowing this gives away my age but GM brought out the 327 in late 1964. Great engine strong long life if maintained. The parent engine to the 350. It is possible your vessel came with any number of engines and later they where changed out to 350.s Look for engine numbers, on intake or front of block, transmission ID might help ID the engines as well. They bot where GM V-8s so they share similar look. I worked on many in my time, dont know now if I could tell just by looking. If you get more Info post it possible we can help further"
