Ported Edelbrock versus W2 out of the box !

I’m not really the small block Mopar authority...... so I rarely see any of the higher end stuff unless it finds itself here for freshening.
Never had any W9’s here(or W7’s, and only one set of W8’s), and the Vics are still pretty new to the market.
I think I’ve only had 2 or 3 sets of W5’s here...... years ago.

On that RPM headed motor...... it wasn’t pump gas. Iirc, about 11.7:1.
Heads flowed 285-ish(I’ve never figured out where the 300+ magic is with those), cam was like 264/268-108, .640-ish, 1.5 rockers.
It was built using an R block though...... 4.100 x 4.00.

Flow numbers between your numbers are pretty close til after .500 on the intake side.
