Hey I have an 85 GT with an Edelbrock Torker II manifold. I was thinking of getting an RPM Air Gap, do you think i will tell the difference from the "Torker"?
I was also thinking about getting a
K&N Xtreme Filter kit. (The filter that replaces the regular lid)
Should this make a difference?
While it's true that the Torker will have less low and
maybe mid-range torque and throttle response than
a dual plane, your stock cyl heads won't make use
of any good intake's potential.
The RPM Air Gap is the best dual plane, period, but
won't do you much good without better heads.
If you do ANY cool/cold weather driving, consider
a regular Perf RPM instead - same intake just
without the Air Gap. You'd hardly notice the diff,
and you'd be a whole lot better off in cooler/cold
weather for cold start and driveability esp. until
the engine is thoroughly warmed.
For economical head upgrades, consider at minimum
GT40's, or GT40Ps, or look for a good used pair of
aftermarket (I found a good lo miles pair of Ebrock
Perf's for $600). Also look at that recent link about
Tri-State cyl heads in here.
A good way to upgrade your cam without buying
a cam is to install higher lift rockers. I found a used set
of 1.72's quite reasonable. Then virtually any type
of header is an improvement over stock esp. with
upgraded intake system, and THEN you could make
good use of a good intake.
Otherwise, for stock heads the regular Performer would
be a much better match, and is surprisingly good up
to around 5k rpm.
