    Do you need a starter gear?

    plate

    It's called a flexplate for a reason and billet 4130 is a flywheel. Coan says aluminum absorbs some of the loading that the rear main will see. I've heard of lencodrives being really sensitive to flywheel runout.
    We run a thick steel CSR with good results on a chevy. We do have the rear main modified for better oiling.
    I have 2 reactors sitting..scared to try them.

    You will break the Reactor, throw it away. We've run the aluminum CSR for years with no issues. The Lencodrive pump is sensitive on runout. You'll need to bolt the converter up and measure the runout. Once you find a position that's under .010 mark it somehow so you know. The all billet ones are perfect so if you run that don't bother. If you dont need a starter gear contact me; I have the baddest flexplate around!
