balancer

a stock 5.0 that is not a High output has a 28oz balance where as a high output has a 50 oz balance. the timing cover should work. only a couple differences in timing covers as long as its not an older one it should. 302 and 351w have the same timing covers. If its carb'ed it has a fuel pump provision and if its efi it doesnt. Althought some older efi timing covers had the provisions and had plates on them I think. As long as the truck cover is a 5.0 it should work.
 
Most strokers are not of 50oz. imbalance.

Some balancers have a weight you can add to change it's imbalance.
