TDSmith,
I bought a Cobra from a show with a 351W that was already set up with a Victor Jr intake. It also had Victor Jr. heads, a pretty lumpy cam (will not idle under 1000 rpm), a Holley 750 double pumper, and a MSD pro billet distributor.
The car, exhibited very poor driveability, and the vacumn signal was so low from the small vacumn port on the Holley that with the radical cam the power brakes were very scarey.
I've since had the manifold changed to an Edelbrock RPM Air Gap and the car has totally transformed. Not only does drive better there's a vacumn port on the RPM that wasn't available on the Victor Jr.
I think the RPM Air Gap even looks better than the Victor Jr. with 8 individual runners vs. the webs that paired runners on the Victor Jr.
You may want to ask the SPF guys if an Air Gap will fit, they are very tall. It fits fine in my BDR with a 3" tall, 14" diameter K&N. I've seen a 351W in a SPF with the "oval" Cobra filter and the non air gap Performer RPM (much shorter) and he had to do some fitting to make it work.
Samurai - If you haven't found a 351W Victor Jr. yet and you'd be interested in a perfect one with only 600 miles on it let me know.
