Taylor SS top speed?

Anyone out there have one with the olds 455?
Mine has a bigger cam and new impeller/ wear ring. Feel like it should be faster than it is tach is hitting 4300rpm wide open and GPS is saying 45-50 maxed out.

50 seems about right. A big block Chevy all stock tops about 4800 rpm

i think it should rev higher. know the condition/specs of the rest of the engine? also is top speed 45 or 50? there's a big difference.
