Ari, sixpackgut, do either of you have or have you seen an actual dyno plot for a good running 440 with one of these intakes. Over the years I have heard discussion, seen timeslips, and read how they have more torque than pretty much all other options for the 440. From what I can gather I would expect the peak to be just at or over 4500rpm. But that is all I have is second or third hand qualitative information.
I did read this article: http://www.moparmusclemagazine.com/techa...formance_parts/
But a few issues. Some old "dyno mule" with 10:1 and a set of SR heads. A random camshaft with the wrong rocker ratio, parts from "around the shop" and limited time to sort things out. So, not exactly a stellar example. I would expect you would want closer to 11:1 with aluminum heads to start with...

What seems a little off to me, other than the torque number is a little on the low side, is that the torque is dropping off fast over 4500rpm and every other engine in this competition does not start falling off until over 5500rpm.
