Howdy, Question for you mustang folks.. starting a car project basically starting the car from scratch. Couple questions regarding a few components I want to swap around: - Will a 4.6L engine block work with 4V cobra heads? - If I get a bored out 4.6L block (new 5.0L from ford racing), will the heads fit on those as well? I guess my only question is in regards to the 4V cylinder heads bolting up. I shouldn't have any issues with the remaining forged components going into this beast. Thanks for the help!
