Cliff, I know you probably posted it previously, but have you tested the Holley SD, Torker II or a Victor against the factory iron intakes? Just curious if any of them are an advantage on a street car?
When the HSD first came out, I used them on a couple of mostly stock low compression engines. One was a 77 T/A 400 4 speed, the other was a 73 T/A, 455 with a T 400. The 77 had 3.23 gears and the 73 had 3.08 gears, I thought that both cars picked up over the iron intakes, but I know you've tested a plethora of intakes against the iron intake.
I also had a mildly built 455 in a 75 T/A with a 3.23 axle, with with ported 5C heads that I ran an late iron intake with the EGR system disabled that would run very well.
All the intakes were bone stock, just trying to get an idea for my next project car, if I should bother to try a single plane, or stick with an iron intake. I would as always, be running a Q Jet on my car, no holleys on my stuff.
Thanks in advance.
