Description
ROTATING ASSEMBLIES READY FOR CRUISING OR RACING!
These Rotating Assemblies are Completely Balanced at Motorsports Unlimited using our state of the art, CWT Industries Multi-Bal 5500. Don’t be fooled by others claiming to be factory balanced assemblies — that just means that the individual components are weight matched sets, such as the pistons and rods. We individually weigh each component (and correct if necessary) to achieve a Bob weight for that particular Rotating Assembly, then we machine the crankshaft to match the bob weight. You will also be supplied a Bobweight card and Balance sheet for your Rotating Assembly. For more information on why you should have us balance and build your Rotating Assembly, please check out our Tech Article on the home page.
These Rotating Assemblies are completely balanced and include everything you need to completely stroke your 350 small block Chevy into a 383 stroker. This Rotating Assembly kit includes the following:
