Here's what Hughes has on their site about this cam:
6 Pack Resto
Our 6 pack replacement cams have the same overlap as the OEM 6 pack, same duration @ .050" on the intake with a reduced exhaust duration. We have more area under the curve for better breathing.
Recurved distributor and upgraded ignition, headers, hot street OEM heads. Designed for use with H.P. cast iron exhaust manifolds.
I'll give Hughes a call to see what they have to say about this one, but it appears that they were thinking about manifolds from the get-go.
The Fury is heavier than my Valiant, but not by a huge amount - iron everything in the Valiant, and it's 3,600# with me in it. The Fury has a 3.23SG out back, 2.5" TTI's, and a 2200rpm converter, so she's really a plus-size GTX.
