1 3/4" Headers Verses 1 7/8" on a Healthy 408....Is There a Big Difference??

All this header talk in many ways is directed at people who want to get every hundredth out of a car they can.... class racers, etc, etc.
Me, ... not so much. Whether my car runs 10.65 or 10.75 because of using one header or another, I could care less at this point. I am going to bracket and index race it, so every last tenth isnt needed.
I have to look at ease of installing, cost, and other factors first.
If i cared about going fast, i wouldnt be sticking tiny eddie heads on a 418 inch motor in the first place..lol. Or for that matter, even Trick flows, if i had them... too small as well
I will know if it runs as it should, that's good enough for me at this point.


Very true. I learned at age 17 I hated cheap headers. So I just never compromise on that.

I think if you change headers and do nothing else and you gain 15 HP that’s a HUGE gain on a tuned engine. I lose sleep at night over less than that.

I was born a generation too late. Maybe two.
