Before my brother moved to Kansas last year, he worked the 10 years previous at an auto machine shop. They do performance and stock rebuilds. I asked him how good the newer Hemis were and how easy was the rebuild. Rebuild heads, over bore ect. He had never saw a Hemi in for a rebuild. 10 years and no Hemi. I think that speaks volumes to how well put together the new Hemis are. Said he did alot of magnums and LTs. As well as 4.6s and LS1s. But never saw a Hemi... gotta love that.
