1972 Dodge Colt

It's a 225. You can't get a lot out of the aluminum block because of the top of the bores are open and they move around. The head gasket is not the best for wear and tear. It's hard to find and expensive. Folks have filled the block, defeats the weight savings of aluminum. Also seen the top surface welded up to make a solid deck. That is expensive and not sure I want to do it. I am going to run my cast iron block to start. Thanks Garrett.
