Super Ford did a big test of intakes on a 5.0L crate motor. There were lots
of intakes including the Torker II and a reproduction Tiger intake (a low
rise intake, not the F4B. The test was conducted before the Performer
RPM and Weiand Stealth high rise dual plane intakes became available
though. The only high rise tested was the Cobra reproduction intake.
As I remember, Weiand Xcelerator was the winner. As far as heights go,
it specs out with an A/B measurement of 3.75" and 4.88". The Stealth
is very similar to the RPM and measures 4.35" and 5.59".

I like the way my F4B works, but I have had been using it for the past
twenty years now and don't really know how much better (or worse) some of
the newer manifolds might work. I might be tempted to take Dan's advice and
try the Weiand Xcelerator. Any data comparing it to the Performer RPM?
(That you trust that is.) Also, are there any data comparing the F4B to one
of the popular modern intakes? Would prefer though, all else being more or
less equal, to stick with the parts that are contemporary with the car.
P.S., I probably should mention, for completeness, that there are
variations in where the engine sits, depending on the motor mounts, etc.
Quite a few Tigers out there have the engine lowered and moved back a bit
for clearance and center of gravity reasons.
