Well, YOU Can beg to differ but 1/with those 2 posts not wanting to sound Personal you sound like a Typical knocking non-patriotic Aussie. Again I've meet more than a few ( living there) & driven more than a few of Both. IN NZ the Leo G R/T 6 pack Charger/s Walked over Alan Moffits Factory Backed 351C Falcon GTHO on the circuit prompting Moffat to state:" Worlds fastest Chargers here" doing quicker lap times & hauling him in & passing down long back straights.
2/ Having driven & worked on more than a few of both (265 & 318/340/360) don't know what you were driving but a properly tuned split exh man 203hp Hemi would definitely show a clean pair of heel to an ave non hi perf 340ci to approx 80-85mph as previously stated & 3/ I think you've been reading too many of those scathing articles on the hemis furboils, I've seen 'em & read 'em too. Sure that had problems during development just live ANY engine, but IF they were as bad & junk as you claim, they wouldn't have marketed for so long until mitsi Boughy Chrysler AUST out, the Dealers would have been OVERLOADED with warranty claims & if they were such a dog, Why do the roadtest figures speak from themselves ?.
Back to a slab of XXXX or Brisbane bitter.
Bet you Hate the Holden 308ci V8 too.
I've got a practical Education growing up around these engines, Engineers, Repair shops, tuning & hands on experience. I don't just repeat ex some other critical Authors article knocking fashion, that unless its out of Europe its no flaming good:unfortunately an Australian Predilection.
The NSW police used the 340ci Hyway special Chargers...ask any Cop of the time in pursuit which powerplant under the bonnet (hood) he preferred. Talk can be cheap.
Cheers Cobber.
