I currently have a 9.2 small block Ford 335 series engine in my 90 Mustang. It has 4 bolt main caps and is 4 bolt on all 5 main bearing caps right from Ford. It is a Cleveland. D2 block. I am currently building anoth D2 4Bolt Cleveland block to replace my current engine. Just because I want to go faster on pump gas without a power adder than I currently do now.
