'65 Barracuda wants to breathe

Duals off the stock manifolds will let the engine breathe much better. :)

I have added duals off the stock manifolds, to several small block 273 and 318 Mopars, the first time
was in 1977, well worth the slight cost, vs single exhaust.

Headers in a Mopar are a pain, and not worth the hassles for an added
10-20 hp; on a street car; in my opinion. ;)

I am using Dynomax Superturbos under my Valiant.
