I've ported at least 100 of the ProComp Air Gap Dual Plane the work well.
Part number is PCEPC2026. I sell all of mine port matched to Fel-pro 1205 and for myself I debur the plenum and run a polished tapered spacer.
I'd rather use the SummitRacing SUM-226010 because they hold their value better than a procomp.
I've tested against the Torquelink and the the dual planes always go south past 4000 compared to the link keeps on pulling. Just the link is damn tall you need a cowl induction for sure.
Street or Strip as long as your driving it for Speed drive it the way it was intended flat to the floor. :twisted:
But I'm crazy I drive my C10 Blazer 20 miles a day and it gets 4-5mpg but on the highway nothing under 85mph. 8)
