We are going to run the tilton flywheel package this year and need info on how to balance a 400 crank with it. Do any of you run the cheap balance plate that like speedway sells? Do you balance internal or do you run a 350 crank? Thanks guys, its getting close to that time of year!!!!

There are several people making weld on plates . They will weld to the rear flange of your crank . After welded , you will internal balance the back of the crank , the front can remain external if you want. Or , for the front of the crank , you can switch to a 350 balancer and use a slug of Mallory in the front counter weight and then internal balance the front as well . Hope this helps !

Hi There -- I have run both 400's and 383's with that setup. How it works, the cranks are externally balanced. You run a 400 balancer (or a fluidampr or some other HP balancer for an externally balanced small block), then a neutral balanced flywheel (like the tilton) with the porkchop bolted between the crank and the flywheel. They work great. Just don't forget to put it on, or the motor won't hold together long because of the out of balance. To be sure you get it right, take the porkchop, balancer, crank, clutch setup, rods/pistons, rings, and bearings all in when you have the motor balanced.

Hope this me if you have any other questions...thanks!
