Looking for advice, BB headers vs. HP manifolds

PRH said
You’re saying the manifolds are better than FW headers.

So, your position is that there would be over 90hp difference between chassis headers and FW headers?

My experience for Mopar powered cars running in the FAST class..........I have dyno tested the motors for the 2 quickest and fastest 6bbl cars, and the 2 quickest and fastest 4bbl BB’s, along with the quickest and fastest SB Mopar.

What they make for power for the amount of $$$ and effort applied...... is not impressive.
Until you add the stipulation.......”with ex manifolds”.
Manifolds are a huge impediment for making any real power.

Your cam with manifolds vs my cam with FW headers?.......... I really like my chances.

I agree with you that manifolds are a big power loser.

I'm saying that FW headers are maybe, maybe a bit better than manifolds. Maybe. They are way too long and usually the primaries are way too small along with small collectors.

If I had two choices between FW headers and manifolds, I'd pick the manifolds every day of the week, and get a cam ground to do as much as you can with the manifolds.

That's what I'm saying.
