I believe the Street Dominator was a small port, long runner single plane. BUT it is a single plane. A single plane will cost you a little bit of low end response, but will perform great once the engine is up "on the cam". I would say that if you have a traction problem this manifold might help you kill off a little low end torque and hook up better. On the street, especially with a mild cam (less than 230 @.050), and a low stall torque converter, you will probably notice a lack of response. But then again, if you have one sitting around gathering dust, by all means give it a shot.
A friend of mine in the Army had this manifold on his 318 Ramcharger. Engine had 280/.474" Purple Shaft, Holley 1850, B&M Holeshot converter, and Hedman Hedders w/2.25" duals. Ran like a raped ape! Oh, it had 4.10"s with 33" tires too.
