Thanks Kelly I was wondering myself about the rear bolt pattern of the latest Hemis and the V-10. I'm leaning strongly towards a stroker 340. That way it appears like a small block and packs a lot of punch. But the weight or lack there of will allow a moderate amount of handling. I'm also interested in a nice 4 wheel disc brake package. I want this car to haul and handle and stop as good as technology will allow. I've also toyed with the idea of a 6.4 6-speed swap.
