finally threw out the "custom calibration" on the two four barrel carbs.
went straight to the book and jetted ONE notch richer than the factory "out of the box" jetting / metering rods for the Eldelbrock #1406. Besides it running and sounding like a Hemi should....the motor feels like it has mucho more HP.....significant!
live and learn ....and hopefully I'm not done with either.
anybody ready for a free rev...WHHHHOPPAAAAA!
