Hey guys,

I'm in the process of getting my rotating assembly balanced, and I bought a new forged Eagle crank, my machinist said it was set up to be internally balanced. Will a regular neutrally balanced 350 flexplate work? I just ordered an SFI aproved 153 tooth neutrally balanced flexplate from Jegs and was wondering if it will bolt up alright. Thanks.

My Jegster flex plate is for externally balanced. Most of the aftermarket ones are internal though for whatever reason. If it has the weight welded on it then it's externally balanced.

Depends if it has the correct small bolt circle to fit the flange on your crank.
