that sounds really high!! I use a very reputable company here in san diego and i get the SHOP price of typically 80.00 bucks(ive done 383,350,427,&406) . Most of the machine shops here sublet balancing to the same company i use ,BUT they mark it up anywhere from 150.00-250.00 . So even with the markup they dont charge 350.00 !!!! shop around if you can find other balance shops.
This would put the price up around where you were quoted. I have one on the balancer right now that needs one slug in the front counterweight. then call hye tech, he does good work and is cheap. I got my shortblock out the door minus cam and oil pump for a grand. I can't imagine him charging 350 for a balance job.
For a 350 or 383? I'd be willing to just go ahead and buy the shorblock.
for a 350 that was without the oil pump, harmonic balancer, and cam and lifters. Thing runs good and if I had to do it again I would spend a little more for a 383 but was working on a budget and figured the muncie will thank me. Sod the owner is a stand up guy. It took him less than a week to finish my shortblock.
