Crackedback,this is for my 66 Dart which I think is in the 2700lb. range?(I haven,t weighed it yet)I,m probably gonna end up buying Eddy,s done already.These will be my last heads purchased.
You can get 575-600 out of ede's and that's about the limit. That type of engine would easily push a 66 Dart in that weight range to the times/mph you desire. There are a few guys running mid 9's with ede's in cars that weigh in at 2700.
A race engine to one person, may not be much of a race engine to another. If you want something in excess of 600hp, look elsewhere for heads.
