You just have to wait while he finished the 246GT Ferrari, 904 and 906 Porsches, etc,
I have used Gromm Racing in San Jose (near air port). Bob runs a very old school, cash only shop. He is meticulous, and I've been very pleased with both jobs. He starts with weighing and shaving from the con rods up. Then he spins and balances the crank, and flywheel bits, lightening as he goes. Don't know the lightening formula. I've been totally please with the smoothness of both builds. Very reasonable price and quick turnover.
