I'll be getting a Quick D Throttle Body soon for my 4.7L. To me it
represents the best bang for the buck (PLEASE DON'T GET INTO A WHERE'S THE
DYNO RESULTS THREAD--I CAN'T DEAL WITH THAT ISSUE RIGHT NOW-That's not what
this post is about). I trust Tony completely and his partner's machine
work is beyond reproach. There isn't a whole lot you can do with the
4.7L's stock TB, so you're looking for some solution to the inefficent
shaft design, a debur, radiusing, and good polish. They do open it a
little bit, but the casting doesn't allow much. The truth is, though, I
little bit goes a long way when it comes to Carbs and TB's.
For the price and for my needs its all I probably need. I'll have a good
exhaust, a Quick D Intake, the Quick D TB, the 180F thermostat, 4.13
effective gear ratio with sure grip, wide tires, spring clamps, and an MP
Computer if they ever come out. I may do the JBA headers too, but I'm not
sure. Besides a Supercharger and NOS I'm not sure what else I can do to
the little 4.7 Semihemi Cammer. The rest of the focus is on balancing
handling with towing maximum capacity.
Now... What if I did need more flow? A couple of people have worked on
custom billet TB's. Whoa! Very cool! I tend to be a cheap hot rodder
though. To me the cheapest way to more speed is to adapt off the shelf
parts. I know zero about TB's and computer controlled cars. My automotive
education goes from birth to about 1988. All in Mopar race cars. Bracket
cars through Pro Stock. None with anything but a carbuerator or two...or
three.
Then I part my stuff for 10 years. Reemerge from under my rock, its a new
world and I'm clueless.
I was looking at an Edelbrock catalog and they had modified Chevy LT1 70mm
TB's adapted to the Ford 302 for only $200. Well if Ford guys are using
ported LT1 parts, what can we adapt? An adapter to mount about anything on
the 4.7L intake would be an easy machining operation. So the question
would be what considerations are there? Sensors, computer control,
throttle linkage, throttle position, air flow metering, idle
characteristics and controls? What are the issues and possibilites?
Granatelli has a bunch, Edelbrock, Ford Motorsports, and many of the
tuners, not to mention stock offerings. What am I missing???

neighborhood drag strip. Must have been the tire marks all over the
beginning of the straight.
