A major point I am reminding freely,, most of us don't go to the dragstrip on a trailer.....
I got a set of RHS at the end of the year on top of my 408 in a 67 Barracuda, full weight,
small valves, 1.92/1.625, Let me tell you a lot of jaws dropped !
Ran high 11's......and it is a STREET CAR !
Altough next year I want to run in the high 10's, I don't plan on changing for aluminum, the bigger valves, port job, suspension work, good TC will get me there no prob......for almost the cost of a hot dog..................so to speak! lol
