First off I am not a Gen 3 hemi expert, but I do closely monitor their development.

I personally would find a 6.1 hemi heads or a set of Eagle heads. The eagle heads are cheap to buy, and flow very well.

I would run a 5.7 based stroker, with new eagle heads or 6.1 heads. I would use an 04-08 short block to get rid of variable cam timing etc.

The drag pack intake is about 750$ cost to about $1000 retail I believe.

DO NOT upgrade the valve train. My opinion from watching the NHRA stockers, they will live to 8000 RPM. I hear the tie bars for the stands are worth the investment.

The stroker kit is about $2200-$3300.

Dont forget the MSD box to run the coils.

I am watching this as you go. Good luck.
