Re: IML: Tune Up Edelbrock v. AFB

["Hailey (Morgan) Moore" <materialgurl@xxxxxxxxx>]

I just though I would mention that I have a Carter ThermoQuad on my 68
Convertible. It is off of a 1977 Dodge 1 ton truck with a 360. I had
to rebuild it, and I had it on another car with a 360. After some
tuneing I was very pleased with the performance. When I bought my 68
it had a holley on it. I have no idea what kind, but I think it was
whatever came on those cars. I replaced it with an AFB from a 67
Imperial which worked OK, but the car always sounded like it was not
getting the full potential out of it's engine. It would light the rear
tires in the garage nicely, but with the gas to the floor at about
4500 RPMs it sounded like it could use more carburator. The car has
dual exhaust as well. Anyway, I bought a thermoquad compatable intake,
and swapped the carb off the 360 onto the convertible's 440. The
difference is like night and day. I didn't even have to adjust the
idle.

The convertible has never been the same since. On one occasion this
summer I let my best friend's husband drive the car  and he really
supprised someone in a new V8 powered mustang.

I have been in the convertible doing 143 MPH on the highway, although
I have never driven it that fast personaly. The car was still gaining
speed when my friend decided he was scared enough. I think earlyer
imperials are somewhat under carburated personaly.

In case anyone asks, I also noticed a slight gas mileage improvement
with the thermoquad. I think the reason for this is smaller primary
barrels. This also makes it easyer to get a really nice smooth Idle.
