Some of the things that makes the new Hemi look VERY appealing for the future of hot Roding (in my mind anyway ) are:

Naturally the HP and Torque numbers

The retention of the SB belhousing bolt pattern which will of course accept the current transmissions, and also allow the use of older style 727 TF, and readily available manual transmissions.

The aftermarket parts that are starting to show up (Chrysler is apparently already making a carbureted intake ......darn only 1 carb) and "plug and play" harnesses.

But likely the biggest is what looks like the availability these engines are going to have as time goes on. Chrysler is apparently gearing up for just under 1/2 million of these engines a year (according to an article I just total production of the original 426 was only around 11,000 units total). Availability and that old supply and demand thing.could make this VERY common swap material (OK everybody say cookie cutter )

MY only real gripe with the engine is those damn ugly coil packs attached to the valve covers (my minds already going over how to hide them somewhere else).

Keep us posted on the progress of your project, it should be interesting.
