New SFI magnum Flex plate coming soon.
so this is where I stand:
still running cast crank(external balance)
correct balancer(sfi and changeable for internal/external balance)
tci flex plate (neutral) six bolt crank and 7/16 holes for converter bolts)
turbo action converter for 904. 10" with slightly off set bolt pattern
weights to be added to converter for magnum balance.
this set up will easily let me change to internal balance stoker, later this year. simply remove weights from balancer/converter and use tci plate.
motorcity magnum. thoughts/comments? weights are showed for reference only.
