I Was looking to purchase a crank for my project and have seen Mopar Performance cranks with the 8 bolt flange and was wondering if they can be used wth the stock 340 flywheel or flexplate.
Purchase the crank with a 6 bolt flange. It is stock. This way you can purchase parts with ease to match it rather than race parts which would more likely be a heavier duty unit and cost more money than your willing to spend or what is actually needed to spend on.
6 bolt stuff will NOT bolt up to 8 bolt crank , if you are using 4 speed u will need to purchase flywheel, if u are using auto , u will need to purchase flexplate.
Hope this helps.
