Had a 750 cfm Ecarb on a 68 400 that came on the car I bought it. Could never get it tuned. Different jets, rods, springs. It was an older version, but still wasn’t impressed. Found out when I rebuilt the engine, valves were not adjusted correctly. After market cam with adjustment ran down to the bottle neck on stock Pontiac Studs.
Took all the play out of the plungers and actually cracked the seats in the lifter. Well its all better now and I put a Q jet with a factory
Intake manifold. The best part is I traded the carb for a good running Stihl 028 chainsaw! Even up!!
