Today's Gasoline
Richard's Technote:
My Charger makes a pinging noise sometimes when I get on it hard.
There is a guy here who drag races a 1967 Chevelle and his father
works on old cars so I ask him a lot of questions concerning
engines and transmissions. At first I thought it was valve
clatter but he said that it was pinging according to what I was
describing and he said that today’s gas is not as good as it used
to be and that I might need some octane booster. Well, I put in
some octane booster which raises a tank full of gas one octane
level. I only use Amoco 93 in my cars because that is supposed
to be the best but he said that wasn’t good enough. The octane
booster appears to have gotten rid of the pinging but I hate to
have to put it in the car every time I fill it up.
Fitting New Weatherstripping
Bob's Technote:
Below is Goat Farm's answer to fitting new weatherstripping (Good answer)
and I used ArmorAll and rubbed it in with good results too.
Richard can use this answer to for his new weatherstripping too.
He thought we should share this answer with others having the
same issues.
Sometimes the new weatherstrip will snag against the window
glass when you roll them up and down. This is usually just
a temporary inconvenience that goes away within 2 - 3 days.
You may try a lubricant on the rubber seal. I use Lemon
Pledge furniture polish for this. Wipe some over the seal
with a clean cloth, just enough to dampen the surface.
If you feel the weatherstrip is the problem, I would be glad
to replace it for you. Thank you, Bob.
Respectfully,
Ed Cutshall

In addition, here is Randy's helpful comments on the Subject:
Hey, Bob-
How long has that weatherstripping been in place? I've seen
some that had to 'form' to its surroundings for awhile before
allowing the doors to close easily and windows to work properly,
etc. I even saw one case where the owner actually adjusted the
striker plate in the door jamb out some, and allowed the door to
close and then every few days he took it in a little until the
door was flush on the outside. Of course, when new cars are
built, this isn't an option. Maybe some aftermarket / repro
stuff's more dense than original?
Have fun,
-- Randy
C4 Radiator and Leaves
Bob's Technote:
The other day the radiator in my 85 vette cracked in two places. A guy
came out to help me replace it. He said he had never seen a radiator
crack in two places and he had been in the business for over 20 years.
"Leave" it to me! I had previously read where vettes of this era
collected leaves in front of the radiator so I had crawled under and
cleaned the leaves out that were in front of the AC condenser. The AC
condensor is mounted in front of the radiator in a cowl. This article
mentioned that I needed to take the top of radiator cowl off, which
at the time, did not make sense - if I could clean out the leaved in front
of the condensor - what was the problem? It became quite appearent when
we replace the radiator and why the article was advocating to take the
top part of the cowl off. Needed to take the cowl off to replace the
broken radiatior anyway. When we took top of the cowl off we saw
that there was a stash of leaved in between the AC condensor and the
radiator - never seen before - actually blocked 75 percent of the
air flow to the radiator - no wonder it was running a little hot in
warm weather. Now with tne new radiator (minus the extra weight of
the leaves) the car actually stays very cool even in hot weather -
live and learn.

Engine Comparisons

http://en.wikipedia.org/wiki/Chrysler_Hemi_engine#Modern_Hemi
In American Muscle Car episode 'The Fastest Musclecar Engines
of All Time', a 1966 Dodge street Hemi engine, built and tuned
under the factory stock condition, produced 820 HP and 689ft·lb
of torque...at least this is what Hemi supporters would like to
be carved into stone as gospel truth. In actual fact, Darren
Tedder who works at Engine Systems in Tucker Georgia, and who
worked with the producers of the show had this to say about the
episode:
We built 3 motors for the show titled “the fastest muscle
car engines of all time”. We did an L88 Chevy, a 427 tunnel
port FE Ford, and a 426 HEMI for them to dyno test. The
motors were to have things done to them that would have been
done by places like Yenko, Mr Norms, and so on. I have no
idea what kind of spin will be put on this show, but I can
assure all you guys that MOPAR will be properly represented.
Though the Hemi is a pump gas motor, it may have a couple
more twists of the wrench than the others, but don’t tell
any of the Chevy or Ford brethren. Everything had to be put
together from the parts we had available. The end result
should please all you guys. Yes that motor has more work in
it than it should, but we used what we had at the shop for
motors in progress. (note: a 500 cubic inch short block was
in the shop at the time...) Remember television is for
entertainment, much like the internet, so don't read too
much into it. Also, it's not like it was a secret kept from
the production. I worked most of my life in underwater
production. Every thing I've ever shot has had some
unrealistic spin put on it by, post production, or an
executive in the production. Unfortunately in most cases
(not saying this is the case here) the people in post don't
know the first thing about the subject matter. It's just a
fact of TV. Two of the most discrediting things said about
anything are: I saw it on TV, or read it on the internet.
Enjoy it for what is, have a good laugh, and be glad YOU
guys know something the VAST majority of viewers don't.
