Hey guys I am new here and could use a little help, I just bought a 79 K-10 and it had a cracked .060 over 350 block between #1 cylinder and water jacket. It has a Holley street Dominator intake and Holley carb marked 1850-4 / 3215. I cannot find any listings for the carb to see how many cfms. Any and all help is greatly appreciated!!
