383 440 swap. Same flywheel?

You are in luck,you can use the 383 flywheel on the 440 cast crank motor,BUT,you need to re-drill the flywheel to counter balance the unit for the cast crank.Now you ask your self,well how do I do that,and where do I drill it.There are 2-3 holes to be drilled from the spec sheet and needs to be done by a machinist.You can find a good machine shop in most city,s but how has the spec sheet,the answer,I am one of the few that has it,mrmopartech
