    Header Bolts for a 340

    3/4" seems to be the typical length with a 3/8" 6-pt hex head. Sometimes it can be more convenient to leave the studs in the end bolt holes...

    Best header

    X2 on TTI. TTI's may make a bit more more HP and/or help more with any future mods because they are 1 5/8"-1 3/4" stepped while Doug's are 1 5/8"...

    Headers vs. manifolds

    Here is a 360/300hp exhaust dyno test. As mentioned, the more HP, the more headers will help. While the individul differences aren't big, those...

    X pipe H pipe or side by side

    Please tell me the best fit small block headers.

    TTI would be a good choice. They step up from 1 5/8" to 1 3/4" which will help breathing over straight 1 5/8" headers (Doug's). I have them on a...

    do i have to remove.....

    Many people have left the block-to-trans braces off. They probably will interfere, but aren't needed anyway. Plenty of very fast cars without them.

    dyno-max mufflers good / bad?

    Try some jet changes to see if it picks it back up. Maybe 2 numbers all around. If it gets worse, go 2 leaner from the baseline.
