Is this worth the cost.

well I am buying Zeaters carb have most of the stuff to put her together. I am trying to figure out the tranny situation. The 440 has a cast crank. My flywheel is a 10.5 for the 340 same as a 440 and would work on the 440 if it had a steel cran. I ma looking for a factory steel crank to go in so I can use my current flywheel, clutch and pressure plate fron the 340. If I cant find one then I have to explore other options weather another externally ballanced flywheel bolted to my crank will work with my clutch or if that get out of controll then an auto. I dont know. I know I have over $500 ib the flywheel and clutch and plate just to sit around and collect dust aint gonna get it.
