4 barrel LA Intake

Sorry.In the 70's ,Edelbrock released a small runner,dual plane. Was designed, to ramp up intake velocities, WAY over stock. (Pump torque, into stock low compression engines). RPM range, idle to 4000. Used correctly, they do work.Sorry,on abbreviations.

I remember dad debating on getting the S.P.2.P to put on his then new power wagon, he could not decide on the 2bbl version or the 4bbl version.
So the truck stayed stock...Or mom put her foot down.
I would love to have either of them manifolds now in good condition.
