Basically a stock 360 with an RV cam for torque. Right now it's a 2bbl Holley, running rich, and cant be leaned out. I got my hands on a Weiand high rise 4 bbl manifold, and wondered would I be better off going with a Edelbrock 1406, or a Holley 600?

I've heard conflicting views, most people say if I go with the Edelbrock, it wont run right with the Weiand, I'd need a Performer manifold.

Suggestions are appreciated. Thanks
