Wildncrazy is right, as the owner of a 390, it runs harder from bottom to topish than a 360, and as a Mopar guy, who has had them all, loaded to the gills, the 390 will make more power, on the street, easier.
Blah blah blah...get that 390 to the track in a 3400 lb street car and put up some 1/4 mile numbers talk is just that talk,i know what a properly built "stock stroke" 360 will run... time slips don't lie...
