383 missing at 5k rpm
I recently bought a 86 IROC with a 383 stroker motor
Scat Crank, I beam rods,10.5 to 1 compression forged pistons,
High volume oil pump
Dart Iron Eagle heads,215cc intake runner,72ccchamber,
205”/160” valves
Solid roller camshaft, scorpion aluminum roller rockers, stud girdles, bow tie tall valve covers.
Victor aluminum intake with a Holley 750cfm mechanical sec.carb
Long tube headers with Brand new true duel exhaust with moroso bullet mufflers
Holley high volume electric fuel pump Adjustable thermostat.
When I bought it it would rev to 7500 no problem. I had the distributor rebuilt new high torque starter and new 2 1/2" duel exhaust. It seems like it would crap out at progessivly lower rpms like 7200 down to 7000 6500 and so on. Now it's down to 5grand and starts missing like it has a rev limiter or something. I've tried different plugs,distributers and a smaller carb no diff. Any Ideas
