The first thing to consider with this build is to lighten on the rotating mass, going with lighter rods and smaller piston pins which will require custom pistons. Basically you can use Chrysler 426 Hemi connecting rods and have the rod journal diameters turned down and at the same time even have it stroked to get over 500 cubic inches and the advantage to that is the crankshaft can be fully internally balanced. You will be able to get that V6 screaming safely at 5500 rpms but of course those hollow stem sodium filled exhaust valves need to be replaced with solid stem valves. I did at one time have the part numbers for the Cat valves but have not had any luck finding them so a custom set of Manley stainless steel valves would be best. For ignition I'm really thinking about a 3 coil pack from the Buick V6, Thunder V12 has a 6 pack setup for the 702 V12, I'm sure they can figure one out for the V6. As far as induction I'm thinking more of a belt driven roots type blower but it's up to you if you want twin turbo's.
