Default Re: What headers for early c-4 (flyersfan1088)

As far as Jesse just now going to bigger primaries, that statement doesn't exactly put a period on the end of the discussion. Who's to say he shouldn't have done it a long time ago?
He should have. Even with his highly modified 406, running 11's, bigger tubes would have been a benifit. The "period" at the end of the sentence comes from running 10's with a 434 and 1 5/8ths" headers. How bad can they be???
Every engine combo I've ever run through Desk Top Dyno shows bigger gains with the bigger primary size.
Bigger gains...Where? Do you drive your street car at the rpms that peak horsepower (or even torque) is developed, constantly? Take a look at the other end of the curve. The end that you USE. Why don't you take your Desk Top Dyno to the strip, and report your computer's ETs.

RACE ON!!!
