Is this bolt and washer suppose to be here. When I bought the car there wasn’t one but the engine rebuilder put on. Not sure if he just left to install balancer? Now my pulleys won’t fit.

327s did not have bolts to hold on the harmonic balance to the crankshaft from the factory. They were just pressed onto the crank snout. It is a good thing he added it and is recommended. Call your engine guy up tell him your issue.
Just remove the bolt and washer, install your pulleys and either reinstall the bolt and washer or don't. It's up to you. With out bolt and washer....original stock appearance. With bolt and washer.....High RPM heavy duty, More protection against balancer coming off.
