Re: Angled Ram Horn Exhaust Manifolds
There were 2 basic versions of the "angled back" Ram Horn manifolds. One style was used on early Novas and the other style were used on trucks. EVEN THOUGH BOTH ARE ANGLED BACK, THE TRUCK MANIFOLDS AND NOVA MANIFOLDS ARE NOT THE SAME!!!!!!!!!!
The angled back Nova manifolds are bringing big bucks.
NEITHER, repeat, NEITHER WILL FIT A CHEVELLE OR A CAMARO.
The ONLY cast iron (factory) manifolds for a SB that will work are the log style (go under the spark plugs). PERIOD!!!!
UNFORTUNATELY, there was NEVER a 2 1/2in factory ex manifold for the Chevelles.
In the history of the small block Chevy engine, the ONLY 2 1/2in manifolds were the Ram Horn versions for 62-65 hi-perf 327s (ONLY in Vettes and full size cars).
