422 dyno fail

I’ve tested a few real duds over the years.

But the ones that come to mind had some pretty notable deficiencies.

Here’s one......
396bbc. Oval port heads, Comp 280 Magnum cam, ex manifolds, Ede 750, and the big problem...... an SP2P intake.
I don’t remember the tq, but it was low 280’s for hp.
The guy who gave him the recipe for it said it was a solid 400hp combo.
We put some headers on it......35hp improvement.

I ended up getting a small solid cam for it, and an RPM intake.
The Ede carb wasn’t cooperative so I sold him a Speed Demon 650DP.
With the headers it made like 416hp.

Totally different feel with that combo in the car.
The old combo was “done” at about 4500....... and the new combo would easily pull to 6500.
