Default Edelbrock S.P.2-P.

So here is the deal. I was at a garrage sale today and i come across an Edelbrock intake manafold for a 350 chevy. It was used but that doesnt matter because its in good shape. Got it for 25 bucks. The only part numbers in the casting other than "edelbrock" were S.P.2-P. I was going to call up edelbrock and ask them, but i figure i will try here first. I was wondering if anyone knew anything about it, looks like its for the low end but i honstly have no clue. I figure if its not right for my applacation i will just sell it on ebay, for 25 bucks i figure i come up on top either way. thanks
Steve

It's a predecessor to the Performer which itself has gone through a couple of generations. It's a more or less "fuel economy" intake designed during the time of gas lines and shortages.

It will work fine but current designs are better.

Think it would be worth selling it on ebay and geting a more modern design?

They are a low rpm high torque manifold. The runners are longer due to a unique design. Not really the go for a corvette unless you have real tall rear gearing.

Yea get rid of it. In fact there's a question about that exact manifold in the tech section of new Hot Rod Mag. They say it's worthless for performance.

Recycle it into beer cans.

I agree. I had one on my El Camino once. The stock manifold made more power. I also had the Zora manifold, I forget the exact name of it. There is a good reason they aren't available anymore.

You could get the best Performer 2101, the previous one, easily.

I had one on my 69 vette years ago. It was ok. I don't even konw what I did with it? Back in 78-79 PHR magazine ran a series of stories with a 70 Monte Carlo they played with getting more MPG because of the $1.25 a gallon gas prices. This manifold was used along with other mods to get that 70 boat up to 22 mph. They fell flat about 4k rpm.
Hold on to it, maybe you can use it on something else.

I installed a lot of these in the '80's. They were a fuel economy manifold and worked well in that function when combined with a set of headers. I could typically pick up 2-3 MPG over stock intakes with that combination, usually in trucks. They worked especially well on 351M-400 Ford engines. Not a performer at all, but you should have no trouble selling it as a fuel economy aid.
