I just did a vacuum test, the engine is pulling 6-7lb of vacuum. The cams are also set right on the sprocket marks. The cam specs are below, will the L & M actuator function with 6-7lbs of vacuum? The Whipple light spring one will not.
I have a fully built long block with custom grind cams. 479 lift with 247 degrees of duration at .50 intake and exhaust. I have the whipple light spring actuator installed the BACT-1015. The baypass valve barely opens and the engine pops and surges until I hold the valve open then it smoothes...
