kkosche,
I have Torker IIs on both my 385s, the 521 & the 557. They work great! And they give more hood clearance, allowing a large enough air cleaner for some serious airflow. Most taller manifolds force a pretty small filter size, restricting HP quite a bit unless the scoop is made taller...
The new Torker II has a variant that has fuel injector bungs already it it if you're interested in doing port injection. When I did mine ten years ago we had to weld in the bungs which is a bit of a chore. The new manifold is here:
Edelbrock 50665 Edelbrock Victor Series EFI Intake Manifolds
Note the height of the carb pad is 3-7/8" which I think is the same as the Torker II. Don't let the Victor name throw you - I think it's the same manifold.

My experience on the dyno is that there's 400-500 ft-lbs at the back tires, through the C-6 automatic and Jag rear, from 2000 rpm up. Nice!
