s475 408ci I know the s475 on a 408 is not optimal, more suited to a 370, but does anybody here actually run one on their 408. Would I be able to reach 800rwhp with a s475 on a 408?
It will reach close to it but have a TON of backpressure doing it. More then likely pick the heads off the block if not careful. Also boost will come in quick but drop in the upper rpms. 75mm wheel is not enough air to keep up with a 408.
