Do you need an external or internal balance flexplate?
When choosing a new flywheel or flexplate or harmonic balancer for your engine, you will need to know if either will require external balance parts. If, say, building an SBC 400 that requires an external balance flexplate and you use an internal balance flexplate you will get a serious vibration when the engine is running.
What kind of flexplate does a C6 transmission use?
In original applications, it roughly corresponded to the “size” of the vehicle the transmission came in. C6 transmissions could have used either the 157 or 164 tooth flexplates, depending on which case it had. As with the C4, the size of the flexplate generally seemed to follow the size of the car it was used in.
What do you need to know about flexplate bolts?
You will always want to use bolts intended for extreme duty. At its core, the flexplate is a simple metal disk that bolts between the crankshaft and torque converter with a ring of teeth that is engaged by the starter to physically spin the engine during cranking.
What does it mean when your flex plate fails?
