My Lund has the 4.3 Liter V6 and last year I sucked a value when I forgot to put a winterizing water plug back into one of the exhaust manifolds. I torn the motor down and removed intake manifold and one head.
That's when I learned the 4.3 Liter V6 is the SAME as a chev 350 but has two less cylinders.
The BIG difference is the exhaust manifolds - those things must weigh 40 pound each. The only difference in parts is the exhaust manifold gaskets - which were a little more beafy in the marine application.
Other differences is the starter which is a really the same but they say the starter is built for marine applications. In other words it was about $25 more than a standard starter - I couldn't see any real difference.
As far as where the motor hooked to the outdrive I have no idea what is envolved there.
One thing that I was told is that a marine motor is like your pulling a large load up Parley's at full throttle.
Good Luck
