But it was more than the coolness factor.... that is why the 6 pak was rated at more horsepower.
I'll never understand people saying "too much cfm's forces too much into an engine. Especially on vacuum secondaries. That is such a myth and old early 70's talk it's just funny. Cylinders are like syringes. They syphon only so much. Tune to match the air going into the cylinders and let 'er rip! I pulled a 600 off my stock 360 with 2.45's (and at that time no headers) and went to a 770. Guess what? E.T. dropped at the strip.
