Fastman Throttle Bodies - The Fastman

This ^^

Edit** - his "standard modified HEMI TB" is all you need for your truck...unless....!!

I got this one for my truck, and opted for the additional 'backside bore' as well.
It has improved throttle response and provided some more bottom grunt at WOT.

Read his statement at the bottom of his ad "HEMI TB SIZING RECOMMENDS:"
