Headers vs 340 manifolds

post 190 ^
For me. Post count jumps from 187 to 191
stock 340 phase 2 800 cfm carb 308.8 hp @ 5800 phase 3 hooker headers 326.2 hp @5800 = 17.4 hp
Iam the only guy?
Not going to dig out the other 2 dyno rip vids that show the same results.
STOCK 340s gain 20 tops

A 1-5/8 header I am going to assume.

Yea yea, 100%, don’t dig. Not worth the time.

Stock Blue Printed 340s with a good carb and hp 68 to 70 manifolds make 1 hp per cube on there best day they dont jump to 370 hp just from headers with the stock cam.
Sorry, did I say it’ll jump to 370 hp?
Because you keep saying this. As if I said it.
OEM rated it at 275. You just told me above it dyno’d 326.2 hp.

Lets drop the .2 and do some math;

326 - Your dyno run
- 275 - OEM published power
= 52 hp - with a new carb and headers.

The old rule of thumb was said to be 20-25 hp. Just headers.
New carbs were always worth more. I never heard the old timers say “XX” HP gain. Just runs better.
Same with camshafts.

All due respect mr rumble
idgaf either
Ditto, With respect right on back.
