Exclamation

As far as i am concerned, why buy smaller headers when we might be going big later on...that is one of the reasons i chose my 1 7/8"edelgbrock headers.In your case i would for sure.

I had them on my previous car.
For stock NA cubes, unless you are shifting at 6800 rpm or higher, 1 3/4" make for a better set-up because the gains for the bigger tubes don't show up until around 6000 rpm and there will be some low & midrange torque loss.

Any gain from switching isn't worth the investment unless you running lots of gear.

Or lots of cubes. The 408 guys love the 1 7/8".
