I noticed the regular RPM intake is actually cheaper than the performer intake in the summit catalog. I was thinking of replacing the torker II off of my el camino. everything I read say the dual plane is much nicer. Question I have is, first of all is it worth the swap? the truck has a 327, fuelies. unknown cam, 3.73 rear. turbo 350 stock conv. 750 eddy carb. second would the performer be a better choice? I dont want to spend the money for the air gap. just trying to find some real world experience. thanks Jim
