400 to 512

i asked the same question in mopartech since im going to stroke a 400 , the responses were that for street&strip the best stroker kit was 470 , for drag race 500ci because of the oil ring support not so good for the street , and that the 512ci had a bad rod radio ... so im going with the 470ci since the car is going to be a dayli driver :snakeman:

hope this info helps you
