I've noticed racing beat does not make and IDA manifold for the 6 port 13B. Why is that? Wouldn't this be a far superior carb then the Holley 4 bbl? My holley set up cuts out on any hard corners, an IDA would not.

Any comments?

 

There is a discussion in The Other Rotary section on it. Its based alot on opinions and varibles, such as what you like as streetable, power, powerband, and all of that kinda stuff. I'll find the link!
