I am looking for real proven results between the BBK I/M and the Edelbrock Victor X, and which one is better for higher rpms, better power, etc. This is for a GSR if it makes any difference. Anybody with any experience with these two manifolds please fill me in your results and opinions.

my best advice to you would be to check out the all motor dyno thread. i never used either manifold let alone owned a b-series in 6 years. but answers are here you just have to find them for yourself sometimes.

Could you give us a bit more information about your car? Daily driver, drag, road course. What other parts are you planning on using? Is this going to be a 2.0ltr beast with 12.5:1 or a 11:1 basic mild build or a flat out race car?

The Victor X manifold, Optimized for maximum power from 7,000 to 10,000 RPM. If this is a race car this might work for you.
A little more research is needed on your part.

I'll throw in my $.02 since the OP has already ask what I've been wanting to know also B18 or B20 bottom, 12.5:1 CR, ported B16 head ITR cams for now, maybe 9K rpm's, mostly street car and occasional 1320. Performer X?
