1967 Dodge Dart 270

It is. The cam came out of a 318 and got about 50 miles on it before the water jacket on the block cracked so it should be hardened already. I have the locations each of the lifters came out of the donor engine and they all went in the proper locations. I also thought about pouring oil over it before I seal up the intake. This 273 has 86k. It had a stuck valve, bent pushrod, and was burning oil pretty badly. We'll see how it comes out.
