Boom!!!! There it is.
Truer words have never been said.

I’d run a stock 2bbl intake and carb before I put on one of those.

And their “greatness” isn’t limited to SB mopars either.
They suck on everything.

Friend of mine has a 68 Camaro ss 396.
One of the local 396 gurus gave him a recipe for a 400hp hot street build.

9.5cr, comp 280h magnum cam, Ede 750 carb..... sp2p...... no headers.

He wasn’t to impressed with it, and after taking it for a test ride I could see why.
It was absolutely “done”(and wheezing) at 4500.
It really didn’t do anything particularly well. No great throttle response....... it was just a straight up dud.
I tried a Holley on it, which ran better, but didn’t feel like it made any more power.
It did make the motor behave in a way I’ve never experienced before or since.
After about 3500rpm or so, when you rolled the throttle open, you could feel it lose power....... instantly.
Like more throttle opening was messing with what was going on under the carb.

Once he commited to making some changes, he pulled it out and I dynoed it, just as it was in the car, ex manifolds and all.
It made an earth shattering 283hp. Yeh....... that’s pretty close to 400, right?

Headers picked it up about 30hp,

Changed to a small solid cam, rpm a/g, Demon 650dp........ made another 100hp and pulled strong to 6500.

For a mild street sb Mopar, I like the std performer......on 273’s thru 360’s.
