i am in the process of installing a 472 in a car that it is suppose to fit ( 71 monte). been trying for several months now and finally had to send it to a man with a plasma cutter to get it to sit right in the engine bay. If i could do it all over again i do not know if i would. my opinion is not to try it. you are going to run into a ton of troubles. from oil pan problems to clearance issues.
