Misfiring carb 502

93 stock 502 is misfiring. Went the easy route and changed plugs. No help. Misfires at around 2500 rpm's then runs fine. What next?? Ignition coil?? Dig into the carb? .

How old are the plug wires and cap and rotor?

Don't skip the small stuff, 2 years ago is plenty of time for it to crap out. Could be the coil.

This only happens at 2500 RPM? All other RPM's run fine?
