What's in the Box

Info

When running a 383 or 400 S/B Chevy with a 153 tooth flexplate or flywheel, you need to have a balancing plate. These fit between the crankshaft and flexplate and correctly balance the engine without resorting to a big heavy flywheel.

Lets you balance your Small Block Chevy 400 or 383 with a 350 flywheel (manual transmission flywheel or automatic transmission flex plate) and a bolt-on balancing plate. Road and race tested. Allows use of lighter 350 flywheel to rev quicker. Precision stamped steel.

Most applications can use the stock flywheel or flex plate bolts, however if your bolts are at the bare minimum length of thread engagement now you will need to get bolts that are 1/8" longer.

This balance plate is designed to be used with a neutral or internal balance flywheel in order to achieve an external balance engine. You will also need to use the appropriate harmonic balancer for an external balance engine. This fits the 1986-96 one piece rear main small block Chevy engines.

Yes this will work fine if you have an internally balanced flywheel (either tooth count) and would like to install it on an externally balanced 383 engine.

It will if your engine is 1986 or newer with a one piece rear main seal. If you have a 1985 or older two piece rear main seal engine then you will need balance plate 91615375.
