Our stuff is all injected now and it doesn't make that much difference with intake design. Now if you were running methanol, a Jr works great for that.but you're also talking about roughly twice the volume of fuel running through the runners assuming carburetion. Just lost exactly 1 mph on the drag strip, but picked up some ET.
The 302 with a victor jr (in my case) was a turd, but it woke up with the RPM. I've done this twice-once on a 351w and once on a 302. The runner length and tapered cross section. Surely someone out there might trade their RPM for your victor jr. This EFI 351W Hi-Ram intake manifold comes with a 105MM 1986-95 Ford 5.0 throttle body flange side mount top. I'll say it again-the victor JR is a great intake, it's just not great for a street-type car/truck.

Now if I had kept and and bumped the compression up to about 12:1, put a big solid roller in it and a 4500-5000 converter, the JR would have worked great. Be sure the water ports on each end of the gaskets are properly sized. Number 2181 is stock replacement/street legal part for 351W V8s with OEM.

From about 1000 RPM to about 5000-ish, the RPM absolutely KILLS the victor Jr in responsiveness, fuel economy, and the butt-o-meter dyno. The Victor Jr is an excellent intake manifold for the 351w, but it really shines at upper RPM ranges, 5000-7500 is about where it's doing it's best. REPLACEMENT VALVES Intake 1:72 1:94 2:02 1:50 Exhaust 1:60 Exhaust. I think you will be pleasantly surprised by how much more responsive the RPM is over the Victor Jr-especially on a mild engine like yours.
