74 318 crankshaft

you can use this bearing instead of the bushing if the crankshaft is not finished drilled for manual transmission. Use a National Bearing FC-69907 this bearing fits in the register where the converter would go into the crankshaft. If the crank is at least rough drilled far enough about 2/12 inches I believe this will work with nothing additional. I however can not speak to the balancing issue but assume the stroker is externally balanced and the 318 is neutral balanced. You'll likely need a different flywheel.
