Price is realistic, ask me how I know. GLWS.

Iron heads make more heat this making motor power all the way around. I guess he never heard that before.

well i guess if nobody is going to ask, i will, how is this price realistic?

You serious? That is the dumbest thing I have ever heard.

My guess is the iron heads are for salt water. Aluminum no likey.

If you research it you'll see that an iron head retains more heat in the chamber instead of dissipating it like aluminum and will make more power. Prob is most companies don't make big iron heads like there aluminum counterparts, and in a marine engine there are other ways to make the power while controlling chamber temp and detonation.
But 2 engines with the same heads one cast in iron one in aluminum the iron will make more power

until the detonation kills it!

Wait, you posted it and you are asking if it is realistic? Am I missing something here? I thought you were selling it?

Go price out a new build, from a custom builder, with those parts, seems to be realistic to me.

Its a true statment.. just sayin..
