[DeTomaso] Carb problem

[Charles Engles]

Dear Boyd,


          Ah, a recommendation.   You could live with it.  You could fix it
per Mike Drew.   You could get the supertrick Quick Fuel carb specifically
built for your engine per Michael Short.  I have one option between those
two.


         You could visit www.chucknuytten.com and consider sending your
misbehaving carb to him for a custom rebuild to your specs and desires.
IIRC he offers basic, medium and racing mods.  I got tired of being
disappointed by new Holley carbs in years gone by and finally decided to
have him build one for me.  He asks numerous questions about the vehicle,
the engine specifics, drivetrain and your performance priorities.  Both
carbs he built for me were only one carb jet away from optimum on dyno stand
testing with the fresh engine.  Subsequently, the carbs have performed well
and return fuel mileage in the 17-20 mpg range. Turnaround time should be
less than 30 days, IIRC.

         The one problem that I would see with a QFS carb or a CN rebuild is
that optimal results would require your cam specs, which are sadly unknown
to you.


                       Warmest regards,  Chuck Engles

Greetings fellow Panterians,
I am having a problem with my Holley 650 double pumper. Under hard braking
the engine stalls. Rather then trying to rebuild the carb and adjusts the
floats etc. I would prefer to replace it with a new carb. My engine has an
Edelbrock performer intake,an upgraded cam ( I don't know the specific grind
due to the demise of the previous owner who took the build info to his grave
with him) headers,roller rockers, MSD 6al ignition.
I want to avoid the common problem of choosing  a carb with too large a
CFMfor the engine. I would prefer no choke or a manual choke but definitely
not an electrical choke or any vacuum controls. Although looks are secondary
to performance I would like to get a carb that has a finish like the
Edelbrock " Endura shine" finish. I am hoping to find a carb that has a very
quick throttle response.
 I am aware of Holley, Edelbrock, and Demon. I have intentionally excluded
Webers because the manifold and  and 4 Webers are outside my budget. So I
would welcome suggestions along with explanations for your choice and any
technical information that will effect my choice.
Thanks,
Boyd
