thoughts on the edelbrock sp2p manifold

What's aluminum get per pound at a recycler?

That's another edelbrock manifold that should have never been poured.

It made sense in the gas crunchs and did exactly what it was advertised for. I have had been there done thats praise this intake for it's gas milage adding abilty.
There is no performance gain in this intake what-so-ever!

I put an SP2P on my '89 D100 (318 TBI) and it made a large improvement in driveability (which on these trucks was notoriously poor) and a measurable, consistent improvement in fuel economy, compared to the stock iron intake.

LOL, I know it, I know it!

Think about how the runners create that high velocity... restriction. The manifold does not "move" the mixture faster, nor will it "make" more vacuum. Vacuum at idle is a function of cam duration and overlap. If you want strong vacuum, don't go nuts on the cam.

(Exactly!) The intake gas some serious bends in it killing anything and everything.

If you want to run dual 2 barrels, get your head examined. Even if you insist upon reinventing the wheel, why start with a square rock?

Exactly again!
