I have a mild 400, .528 solid cam, old DC Stage 4 heads. I can get a good deal on a set of headers with 2 1/8 primaries. What would I be giving up it terms of torque and horsepower using these headers vs a 1 3/4" primary? Full exhaust street car. Thank you
If you can get a good deal on them, I'd consider buying them and see if you can sell them to a racer, or trade them for some 1-3/4" primary headers. They'd cost a ton of torque on that combo.
