1 3/4" Headers Verses 1 7/8" on a Healthy 408....Is There a Big Difference??
My W2 head 408 made made really close to 550HP with a single 4bbl and TTI 1 5/8-1 3/4 stepped headers.
I recently came across a set of the 1 7/8 TTI W2 headers second hand for a great price. I picked them up, but I'm now on the fence. I'm not certain the gains warrant the effort to swap. Fitment with the stepped headers is great, I hope I'm not inviting a headache if I go to the larger tubes. The collectors change from 3" to 3.5" with the larger headers.
The car is also changing from 3.23 gears to either 3.73 or 3.91 gears, now that I am installing a Gear Vendors, so perhaps the bigger headers will benefit from the gear change?
Thoughts and opinions welcomed.
Headers are in great shape, just needing a little TLC and cleanup.
