Well I took my block in today to get machined and found out that it is aluminum. It totally doesn't look like it. So I don't know if they are all like that or not.
Iron, but it weighs to much for a mustang. I think the alum motors make the nose weight 51%, anything more is not gona be the safest car out there.Claypops said:Ok well I'm replacing those anyways. What's stronger? The iron block or aluminum?
You'll be fineClaypops said:Since they are already sleeved, when it gets board 20 over does it need to be sleeved again? I know nothing about that
