I have used the Edelbrock Torker II on a 440, using a Holley 4150 780 CFM R-3310-1, TF 727B, 4.10 489 case rear. EXCELLENT RESULTS ... crisp throttle response, decent MPG (10-12), good to 5500 RPM in my car, a 71 Dodge Charger 500, WP23U1A*******. I used the Mopar purple shaft cam...284° duration. Great street performance package
IMO, the difference between the Torker I and II, was the configuration of the runners exiting the open plenum. The Torker II had small, cast in place dams, on the floor of the plenum at the begining of the runner and had a slight narrowing of the runner at that intersect point, to help mixture velocity and distribution, especially on #5 & #7 branch to promote reasonably equal cylinder filling. The plugs will show this...
My opinion.....USE THE MANIFOLD with a similar capacity carb. Worked great then....will work great NOW...
Just my opinion of course.
