Re: IML: Tune Up Edelbrock v. AFB

Hi Chris

No, It wasn't a typo. We calculated the speed based on how many RPMs
it was turning, since we know the final drive ratio. My friend who was
driving is a 29 year old mechanical engineer. He is one of the most
interesting car people I have ever met. He has only ever owned one car
himself, but has driven many over the last few years. Currently they
are driving his wifes honda while he hotrods his 73 VW Super Beetle.
It now has porsche brakes and wheels, and a 1600 CC engine with twin
webber carburators. It's a nice machine. It's almost finished. I let
him drive the Imperial in his wedding actualy. There are some
interesting pictures of the bride and groom leaving and burning out in
it after the dance, if anyone wants to see them :-)  The car got a lot
of attention from the wedding party.

I am quite certain of the speed we calculated about 143.6 or
something. I asked Colin about it today, and he said 143.6.

It is not really a stock Imperial, I guess, but it is close to stock

The thremoquad is a good carb, but it combined with lean burn, or
Mopar CAS or one of their other  emition systems of the 70s it can be
a nightmare. Also if the air door on the seccondary barrels is not
adjusted once in a while it  gets slack, and causes horrid performance
problems.

A manual choke is also a good idea with thermoquads, although they do
work fairly well with an automatic choke.
