Carb CFM recommendations

Correction on the Weiand stealth, the port size is 1.96 by 1.00 inch. It's a direct match for the 318 heads with a rated power range of idle to 6800 rpm. It's the Weiand answer to the Edelbrock performer 318-360 but is more closely related to the LD4B.
Weiand Action plus is Weiand's answer to the eddy performer. The Stealth is their answer to the Eddy RPM. The Action Plus has the same width port as a 340/360, but not quite as tall. I like the Action Plus better than the 318/360 performer by edelbrock. I have two Action Plus's and 1 Stealth. Another video I made.....
