Hi everyone,

 I'm getting ready to put the ZZ4 into my 69. Got the tranny, Keisler Tremec TKO 500. Just finishing up detailing the engine compartment. I picked up a 11" Centerforce 1 clutch kit and a 14" flywheel. I know that this engine is internally balanced but someone told me that I should balance the engine and flywheel anyway. Does anyone know if this needs to be done? Any info is appreciated. Thanks, Steve

 

I didn't do mine and have no problems. You are going LOVE that engine

There is no need to rebalance an internally balanced engine.  Just use the correct flywheel and harmonic balancer for an internally balanced engine.   Same as any small block except the 400 or 383 stroker.

Thanks guys, thats what I thought. I'll have more questions in the near future, until then I'll try to get some pics on. You guys are the best.         & nbsp;         & nbsp;    Steve
