Hi All, I Have An 84 Gt 5.0. The Engine Is Stock Except Underdrive Pulleys, 456 Lift 268 Deration Compcam, Stock Carb Jetted Up, No Smog Pump Or Cats, Shorty Headers, H Pipe And Flowmaster 40's. I Also Changed Out The Stock 308 Gears For 373's.
Here Is The Problem, I Just Dumped The Cluctch For The First Time Right Out The Hole Sense The Mods. The Tach Went Straight To 5500 To 6000 Rpms. The Car Started To Pop Or Breakdown A Little So I Backed Off To Get The R's Down And Once It Stopped Spinning I Went To Second And Thats That. The Popping Seem To Be Through The Exhaust Not The Carb That I Think. Can You Help? Did I Float The Valves At 5500 To 6000? Should I Have Pulled Second To Keep The R's Down?
