Well i scored a free engine that was balanced for a flywheel. Now i run an automatic. If i have the engine's balance checked will it affect it from running a flex plate to a fly wheel or can wheight be added to the flex plate to match the original balance. The engine is a 355 with probe pistons i plan on sending this engine out and having it gone through since it was free and a really good starting point for a procomp aluminum headed small block build.

 

If you're having it checked then it may or may not need to be rebalanced.
A good shop can balance the flywheel and flexplates to the same imbalance. Thereby getting the same results.

Just have it checked and go from there.

 

Cool thanks. This engine will be sent out the previous owner had a very reputable shop to the work and it shows im not about to mess that up lol.
