You might drop edelbrock tech support with your engine combo and see what they say. I am currecntly talking the gamble on a small block. I wrote edelbrock tech support and told them my specs and they gave me the thumbs up. Several people have said to me "you will lose all you bottom end!". I just don't think this is going to be the case. I think there will be bottom end lost, but you gain top end. Generally, most cobras have too much bottom end and light the tires at will.
Here is what convinced me to give it a try. Take a look at the graphs on the Parker Funnel web. This is a single plane and they compare it to other single planes. It out flows the Holley Vic Jr. I personally think it does so well because it is 6.5 inches tall. The super victor and victor are in this range. The other interesting thing to note is that TQ also improved

If you are not in a big rush, I will have my dyno results hopefully by the end of august.
