Top End Miss

For the record i run a Holley Blue and regulator which is set at 8.5 psi .On the other hand i have a freind that runs an 11 second 55 Chevy with a nasty solid roller small block sporting a Predator carb ,and spins it all the way to 7500 rpm with a Holley Red pump and has for years ,but i wouldnt do it .I still think the OP problem is in the valvetrain ,and i dont think the carb is too small either.My 408 in my Dart has a 750 Demon on it and i ran a 7.13 @ 95.04 in it a few weeks ago .Not braging on my car or my freinds ,just giving you sum comparisons on carb size vrs ET vrs CU ...
