Standard Holley/Sea Demon Super Sucker Spacer
How does 10 to 15 horsepower sound in only 15 minutes. That's right we've
tested this and now we're believers and users of this awesome product. The
unique design of the center section of this spacer actually speeds up the air
flow into the engine. We all know more air in equals more power out. This unit
works on either single or dual plane intake manifolds with a square flange
carburetor mounting pad. You won't be disappointed.
