Good evening all. I just picked up a 2008 Aspen 5.7 limited. Loving this truck. Had a 2004 Durango 5.7 slt. So far I added a CAI and Borla xs pro. Looking to upgrade the intake manifold for more midrange power. My issue is that the throttle body, housing on my intake manifold, is located at the back (fire wall) side. All of the upgrade, intake manifolds, have the throttle body housing on the front (radiator side). Will the 392 be a direct bolt on. Is extending the throttle body wiring a problem. I'm sure there are plug adapters (extentions) out there. Thank you in advance for your thoughts and suggestions.

 

No, to my knowledge 2009 is the year they updated the hemi’s intake with the throttle body up front. 07-08 are considered to be GEN 1 hemi’s. However, the 6.1 intake bolts right up.
