Has anybody seen the new ProComp Quailifier EFI intake for 5.0's. I found 1 new in box for less than 300.00 shipped. They claim 10 more hp than a Cobra intake,and is so close to a Professional Products & Edlebrock intake that they will interchange uppers & lowers. I have also found ProComp aluminum heads assembled for under 800.00 in 175,190,210cc range. The 175cc heads flow less than the GT40X heads (240cfm to 250cfm @ .550 lift)out of the box but at 300 to 400 dollars less I could almost afford to have them ported and polished. Is there any comments about how good or bad these products are? Is there anybody out there that has used any of these? Its not often that you can buy a set of aluminum heads and intake new for under 1000.00.
