How much power is to be gained going from 1 3/4" mid length headers to 1 7/8" full length headers.
Motor is a 376 with ported 821s, custom tic performance cam, vic jr. 850Holley. Car is a 95mustang with a glide, 4200ati , 4.10gears at 3200lb.
With a 125shot car went 9.44@142. Just trying to get every little bit i can out of it.

LOL. I guess you know how many guys in this section tried it.

I am betting you will pick up some midrange torque.

I went straight to 1 7/8" so no help here.

Edit: Now that I think of it, friend of mine went from 1 3/4 351W headers on his 376 Powered fox, to 1 7/8 custom set. Didn't go any faster, but just fit a lot better.
