So is it a worry about the cast iron spray coating in a cast iron block? I've never seen one out of the block so I've got no idea what it's like.

I've been thinking about putting the m119.960 bottom end and flat top pistons in a bored 4.5 block with 560 heads. High compression short stroke, good(or better at least) head flow. But then as soon as I nuke it I'm out a bunch of money. Lack of a great trans option too. Sadly I'm. Really considering just going LS. IM NOT recommending that for your coupe, but my drift car gets thrashed and run hot overrevved. The stock m117 does take a beating though. I will give it that. Maybe just throw the 3.5 heads on for a bit more punch. Sorry. Rambling.
