65 vette needs Help

[Popzak]

Have a 65 Vette 327/365 hp.Won't go over 4500 rpm in any gear.Has a Crane electronic ignition with rev limiter.I thought previous owner might have set it low.I maxed it out.Same thing.Car runs perfect,but won't go past 4500.Fuel Pump or fuel filter a possibility?
Would appreciate some advice.

Thank You

Bounceing revs at 4500 rpm.I never tried it at idle.

Sorry I took so long to reply.Haven't done much with the Vette till Today
My friend replaced the Rev Limiter with Points
I did some research and found that the Crane Product I purchased was replaced by one Mechanic in over 70 Cars for being Faulty.That's when we changed to Good Old Points.Problem Solved 6500 rpm with no problem

Thank You All for Your Input...
