The block will need clearanced for the additional stroke. This is normal for 383 strokers. This clearancing will need to be performed by installing a piston and rod assembly in each cylinder and using a die grinder as needed for clearance.

You will be able to use an original 1 piece main flex plate with this if you would like but the stock 350 balancer will not work. This kit requires an externally balanced 400 style balancer which is included when you choose the balance option.
