Engine balancing HELP!!

[Caye_nne]

Trying to find someone competent to balance an Alfa V6 engine. Needs to be balanced, crank, flywheel, f-pulley, pistons rods etc reving to 8,000 rpm.

Tried a place who do Bentley engines but they soon gave up because of the 60 degree V, and the need to make bob-weights.

Cheshire/ Manchester area would be great!!

Thanks
