quickest et,s on an edelbrock carby

Interesting thread.

We just dynoed a 408 stroker with a couple carbs. This was our first time playing with an Edelbrock (pn 1412) so we tried the 950 Holley (list 80805) first. It made 533hp & 530/ft with the Holley and the Edelbrock made 518hp & 517lb/ft.

On the surface it sounds like the Holley wins by 15hp but the power curve of the Edelbrock was a thing of beauty while the Holley was full of little bumps and shifts. Basically the Holley was good for WOT and that was about it, while the Edelbrock looked good everywhere

I was impressed with how easy the Edelbrock was to tune and I'll definitely be getting one again.

The only real problem with the Edelbrock on our combo was that it was showing 2.6 to 2.8inches of vacuum at WOT. Basically even at 800cfm the carby is too small. Maybe we can convince Edelbrock to make a 900 or 1000cfm carby. :)

The other thing that impressed us was the price. summit list the 1412 at $399 while Holley Ultra Xp is race carb and cost $850.


518hp and 517lb/ft should see our 70 Dart well into the 11s.
