1 7/8 or 1 3/4
anyone want to share their opinion....car should be making around 440whp 420ft through a 4l60E....gonna get new headers down the line and curious which ones to go with....3/4 make more down low i think? 7/8 make more up top i think? but for my specific power range which would get me down the track the fastest with a 373 gear? thanks

the engine used for this testing was not stock, and compared an old design 1 3/4 to a new design 1 7/8 header. i do appreciate them testing there products i felt it was misleading on some facts. they used a different cam, heads and intake from stock, for a daily driver i would go with a good set of 1/34 on a STOCK engine.

I put 1 7/8 on my old stock motor and it was beautiful. Properly tuned, 1 7/8 gain more everywhere on an LS motor.
