Need help!

I'm new to this site and to boat ownership. Am trying to determine which size engine is in my 1973 Slickraft. It is a 21 footer, has a "OMC" outdrive and several possible engines for that year. It could be a 302 c.i. or 351 c.i. of Ford manufacture. It could also be a 283 c.i. or 350 c.i. engine of Chevy manufacture. I do know that it is all original factory equipment and not a special order. Any leads would be very much appreciated.

Fords have distributors at front of engine, Chevy at rear.
