My friend is buying a shortblock, he wants a Dart block with good internals...its for his turbo mustang. He would prefer to buy it already assembled becuase the machine shops around arent all that. What would be the best way of going about buying a bottom end good for 20psi in a Dart block already assembled? I quoted this just for him, please give some advice.
"Well today I blew a headgasket. I have way to much compression to continue to change hg later on. So I am goin to buy a short and put my top end on it. So I was wondering what would be a good company to buy a short block from. I will probably go with a 331, but I need some help Please."
