Thermoquad on Edelbrock RPM Airgap

The spreadbore tends to make more torque at lower RPM's and provide more top end power per build, not every build responds the same way. Steve Dulich has had a few write ups where he had his TQ out perform the dyno shops Holley.
IMO, a well tuned TQ is a great street strip carb worth looking into.
Remember this carb, the TQ was born and designed to be a race carb before it was redone to be a daily operator for cars.
