Hello all, let's see if we can't figure out what noise my motor is making.

Details:
- Started a week ago
- Fluctuates with RPM
- Sounds like a cross between an exhaust leak (which it's not) and a lifter tapping (impossible) and a pully squeal (impossible, took all belts off and started motor, noise still there)
- Fluids are all good
- Oil pressure is spot on
- Temps are all good
- Gets louder the warmer the motor gets
- Small amount of smoke coming out of the carb (Rochester 4bbl)
- I think it sounds like its coming from towards the rear of the motor, dad thinks more the front.

Motor Specs
350 bored .30, Rochester 4 bbl, XE 262 cam...

Help?
