Question Edlebrock Intake Manifolds??

My bronco came with an aluminum Edelbrock S.P.2-P. 400 intake manifold. Is that different than the Edelbrock Performer 400 intake they sell now?

I came across a Performer 400 for a good price should I pick it up?

Did you go to edelbrocks website and compare the 2 intakes??????? I think that would give you the most accurate info..

I take Prayer Requests. God Bless

I have/had an SP2P on my 77, and yes, they're different. The SP2P is older technology and significantly smaller runners. I'd say the intake allows the truck to fall on it's face about 1500rpm sooner than having a Performer on the same engine.

The SP2P will make slightly more power, off idle, with better response, at lower rpm, but will run out of breath, before the Performer. If your rig is stock, and you never push hard, you will not notice much of a difference between the 2. When the SP first came out, it was presented as more of an "economy" intake, than a power maker. Back in the day, guys were running the SP, with a tiny Holley "Economaster" carb, and wondering where all their get up and go went!

Ok, thanks for the input guys! I did end up picking it up, the size difference in the runners is shocking. I decided to upload some pics for anybody who is interested in seeing the difference.

This is the top view of the Edlebrock S.P.2P Intake Manifold

Here is the top view of the Edlebrock Performer 400 Intake Manifold

Lastly here is a side by side comparison of the runner opening.

I've always referred to the SP2P as the "better than nothing" intake. As in, if you got a cast iron 2bbl, and wanna go 4bbl, the SP2P is better than nothing (but not by much). Alot of guys with Jeep CJ's that run the AMC 304 V8 like them because they get a 4bbl, save some weight and they produce pretty good low end on a stock low compression motor.
