How far can I realistically go with horsepower on a small block before stock exhaust manifolds start being a problem?
Or is the real question, what rpm? Can I get 6000 rpm on stock exhaust manifolds? This 318 is in my 64 Dart and I don't really want to deal with the header headache.
Just want to push this car a bit. 1/4 mile the 12s? 13?s. Will have 904 auto with 8 3/4 3:55 suregrip.
Thanks folks
