Why?

some good points made about the 6.1 vs BB or LA

however, given the added expenses, is it cost effective?

even if it was only $1000 (it's way more) how much more power could you get out of the others?

or if you put efi / good heads (not iron stockers) and other things to make the cost even which would put you down the 1/4 faster? about the only thing I see advantage wise is fuel economy... maybe. that's if you keep your foot out of it. those mid 20's mpg numbers that were quoted for the newer mopars is if you feather the gas pedal lol.

again when I mentioned valve train maintenance for the new hemi's in race cars was what I said... for race cars. big lift, high HP they tend to have valve train / short block issues if you go on the high side. not talking 400-500hp.
