Currently looking for an intake manifold to go on the motor a buddy is building me. Wanting one of the following:

Edelbrock SP2P
Offenhauser Dual Port
Holley Street Dominator "Z" Series

If anyone has one of these they want to part with, let me know. Much preferred to be the 4bbl variants. Thanks!

    I'm guessing you are building a super mild 318 with a small carb - as the tiny runners on those intakes aren't good for anything else. Honestly, the only benefit over typical stock cast iron 4V intakes would be weight savings. Plenty of other easier to find modern manifolds exist that give up nothing on the low end and allow for more power in the over 4,000 RPM range for a bunch less money. An LD 340 is hard to beat for a small block and will cost you nothing in power or MPG with an appropriate carb. Were it my motor I'd use later swirl port or Magnum heads (or at minimum a set of garden variety 360 heads) and an easily found Edelbrock Performer.

    Going for a pretty much all out mpg/daily driver build to do a little light towing once or twice a year, so those tiny runners are certainly what I'm after. Thank you gentlemen.
