454 4 bolt a mag motor

is the only difference between a mag and a non mag motor a 4 bolt main set up? I just brought the new boat home and the stock motor was just put in for the summer. i ran the 3's of the block and it came back a 4 bolt main. does this mean it is a mag or are there other things that could determine it too?

The Mag has better crank, rods pistons and heads than the non mag.

What does "I ran the 3's of the block" mean?

I think he meant the "#'s" and didn't hit the shift key......

I believe that all Gen V and Gen VI (1990 and newer) 454s have 4 blot mains.
The Mag/HO has forged internals vs. casts in the low out put engine.
