Which intake to keep for my 67 273

To bad the LD4B wasn't a choice as some guys can't read.... LOL
A VERY GOOD INTAKE FOR SURE!

Considering the 2 choices, the Weiand is the clear winner. The sp2p was developed during the gas crunch years to help with mileage. Leave that one alone. Put it on the car designed for daily work commutes and long distance driving.

Use the Weiand for a power build up.
