WOW! Thanks for the link Scott. In all fairness, I don't know anything about the people who put that article together and Dennis' 11.72 time @ 116.92mph with his Windsor using Pro Comp 210's is certainly respectable, but it does raise my concern over my set of Pro Comp 210's! Since my engine is together and ready for the dyno, I'm certainly going to go ahead and dyno it as is. But if my 424W doesn't clear the 500hp mark with similar torque numbers, then I will know that something is wrong!!! Now I know what component I will change first if it doesn't put up good numbers!!!
Another thing to consider if you are trying to save money on your engine build is that if you have to pay someone else to do your port-matching and clean up the runners, then you probably could have bought a set of AFR's or atleast Vic Jr.'s for the same investment! I was able to do my own port work so I have under $800 total tied up in my set fully assembled. We'll see very soon (hopefully this coming week) if my Pro Comps were truly a bargain!!!!
