Just not a big fan of the extra heat the PD blowers make in the grand scheme of things. A pro-charger would be neat, but they are even more!!!

True, but they're using a pretty aggressive cam to get those numbers which means most of those gains are likely to come in the high-RPM range w/ little on the bottom end, not to mention the driveability might suffer. Sure, you can get gears (I did and highly recommend them), but when you add the cost of those & their install (unless the prices have finally dropped since I had mine done), you're getting close to the cost of a S/C. Granted, I'm probably going to stick w/ N/A power (heads & cam), but can get to 450+ rwhp for about $2K less, labor included and, depending on cam specs, will have more "useable" power across the RPM band. I could go w/ a more aggressive cam, like the Mast one, and get more peak HP, but how often will I be able to rev to 6K+ RPMs to use it? Rarely.
