well go read,
there are 100s if not 1000s of posts here with personal experience based on that combo...
what combo? the stream isn't specified.
and the personal experience is ALL OVER THE BOARD.
i've yet to read from ne1 posting they SWAPPED engines big way up...
but there are lots of posts with personal reports.
i loathe posting personal experience, in many cases it is worse than NO info...
and the specifics matter ENTIRELY while the personal reports seldom include important details...
so it becomes LIKE mpg reports (which are all fish stories) while towing.
i do have 75,000-100, 000 miles of 454/airstream driving experience...
that figure is JUST in the rockies, crossing the c/d, wyoming, the cascades, bc rockies and so on...
i've also used that combo in the keystone state (about 2-3k miles)
they is NO COMPARISON.
above 5,000 feet the towing changes significantly
from 8000 ft and climbin to 10 or 11,000 is many times different than the 5,000 ft issues.
SLOW UP HILL really really slow, with brakes and gearing and steering and tires tested on the downslopes...
often miles and miles of downslopes producing stresses that are different but JUST AS TOUGH...
as the UPslopes.
climbing at 15-30 miles per hour on the interstates WITHOUT truck lanes or in tunnels OR when problems happen is no fun.
blocking traffic is no fun.
parking and waiting for a cool down is no fun.
smoking the brakes or tranny DOWNHILL is no fun.
and so on.
of course THAT personal experience is not with the 6 l or 8 liter, but rather a 70s 454...
that was TWEAKED TO THE MAX and moved at 80+ mph easily on the flats (even at altitude)
eat it with a shake of salt.
1 time doing the rockies, and the report is..."i've done this and survived, so i must be cool..."
but take these routes many times and the wimpy performance matters, and the ratings become IRRELEVANT.
blocking traffic, getting crap tossed at your slow moving rig, having the fuzz suggest MOVING to the shoulder is no fun...
altitude tests gear. pa has NO altitude and simply doesn't compare to the high plains or big rocks in da west.
again since NO UPGRADES are planned what's the point of reports good or bad, just go and try it yourself.

this statement is patently incorrect and it's so incorrect that explaining WHY would require starting so far back...
and it's been done already.
IF you've solved the rating puzzle, and
IF all the forums have ALL the same arguments...
then it seems likely,
they must also have ALL the same personal experience reports too...
