Did issue get resolved ?



1971 Superbee - My 383/432 Stroker is having the same issues since rebuild last year

Auto Trans Rebuilt - Turbo Action Auto Valve Body - Works Perfect

3:91 Sure Grip

Motor runs awesome , idle , cruise , off idle , full throttle perfect up until about 5,200 Rpms and then it starts falling flat , like running out of fuel - Get out of the throttle , and then back into the throttle and off it goes

Off idle this motor will destroy the tires - 20/30 mph and into the throttle car sideways

There are times say cruising in first gear , jam the throttle control the tires , Rpms come up until 5,500 Rpms shift into second and it starts sputtering going flat like mentioned after 5,000 Rpms in second

All eight cold cranking compression , air cleaner off throttle plates closed 195psi dead nuts all eight , verified two gauges

1971 Carter AVS 4968 750cfm initially , converted over to Edelbrock jets and metering rods - Ran pretty damn good honestly up until mentioned

Now running Edelbrock AVS 2 800 - Plug color decent with factory jetting , went slightly leaner on cruise metering rods - Same issue at higher Rpms - Tried .107 Secondary Jets , same issue

This carb off idle , cruise is just plain awesome , so smooth , but again higher Rpms

Mechanical fuel pump - Pump Rod and cam is perfect
Factory 5/16” fuel line
1971 Factory vapor line to three nipple breather on valve cover

Tried three different coils

Now on second carb

Thanx Scott
