5.7 Hemi install

Guy's I have my reservations about the bottom ends on the 5.7's but after coming across a smoking deal I picked up a complete 2005 5.7 from starter to A/C compressor, wiring harness, PCM, 545RFE guy bought it off Ebay back in November 2009 for $3750 and I just bought it today for $1100.00 I am installing it into a 69 Charger Daytona clone, I am a member over on B bodies only aand they said this was the place to ask what I need to do, it came out of a 2005 Rumblebee, I know the trans tunnel needs modified along with the torsion bar crossmember for the 5 speed A/T, I really don't plan on modifying the engine the way I take it I have to have to have a standalone wiring if I put a bigger cam in it. Any help appreciated!!!:D
