TH 400 flex plate??? Please Help.

Let me bring you up to speed first of all. I am doing a t56 to 400 swap. I bought a flexplate from a guy on here and I went to install it, and I notice that the dowel on the crank does not fit in the holes on the flex plate. The flex plate hole where the dowel goes is threaded

Also it is a Callies crank that it is being bolted to , not a stock ls1 crank. Does that make a difference? Does the flex plate not need a dowel? Also do you think I need a different flex plate? It has a spacer for the 400.

what kind of flexplate is it? if it's not an sfi apporved one, I'd suggest getting one. Hughes makes a nice one that's not too expensive and works good... I've had one in my car for a year now and it's been fine.

My meziere has a provision for a dowel pin off of the crank... Maybe you should check them out.. Definitely one of the nicer ones out there...

do a search for huges racing transmissions on google. Eastside is a Hughes dealer, you can call them and they could order it for you as well if need be.
