What did you end up doing for a flywheel? Seems like I remember seeing you say somewhere that it was an issue when you swapped to the hemi.

My project dead-ended. The car really was too far gone and the solid 74 Duster 360 4 speed sitting next to it made more sense. I couldn't keep them both and so the Valiant is now a new Toyota or something. I did save the crossmember, though, and I so I still have all of the R154 stuff. Struggling to cut up the floor of an original 4 speed Duster 360 so it hasn't made it's way in there. Might still do it, though.
