• Flexplate for Automatic transmission. (If you are using this for a manual transmission we highly suggest sending in your flywheel and pressure plate so we can achieve the best balancing job possible for your engine. Also, now is a great time to upgrade your clutch. Get with our team to talk about the options we have available for you!)

  What you need to know about Choate Vs. the Competition. We have put together a list of videos for all processes we do to this engine. It is your responsibility to educate yourself about the differences.

To do so we made that easier with this compilation of videos!

This is why we machine the crankshaft for an upgraded keyway!

This is why we square deck the block!

This is why we balance the rotational assembly!

This is why we torque plate hone!

Why we only use the Rottler hone for YOUR engine!

Why do we encourage you to buy a long block instead of a short block?
