454/365 rpm

Factory rated 454/365hp was definitely an oval port head. If this is a legal stock engine the cam profile and associated hardware typically dictates that shift rpm will be significantly higher than a "basic" 454. Numerous factors to consider as with any engine but generally I can say 6500 -6700 would not surprise me.

Not many will make much power above 6300
