RE: FTE Perf - Good years for 460?

Bill: I have a 71 block with the 73 heads (low comnpression). I used the
Crane 260 degree cam for low end and the motor has more power and torque
than I know what to do with. I tow a 4000 lb boat up the baker grade at 65
so don't worry about the camper, you'll be fine.

The truck's primary heavy job will be carrying a fully self contained 10.5'
Vacationeer Camper, wife, kids and stuff on summer vacations. Last year I
from California to the Grand Canyon and had to lock it in 2nd and go about
35 mph
on hilly parts of hwy. 40. I suppose what I want is "healthy" vs. ultimate
rpm horsepower, healthy enough to maintain the speed limit as I drive up and
the interstate! ;-) (forgot: old motor=360)
It looks like 9-something:1 would be the the best overall ratio. If I
the book I saw right, the ratios dropped from the 10's to the eight' without
anything inbetween? Would the low compression motors be just fine for what I
in mind? Can you put high compression heads on a low compression motor and
get an
averaging out? Is this where head shaving comes in? Am I asking
enough annoying questions??

I think it was 0-5500 and for about $500, it seems like a good deal. At my
knowledge level,
the matched components have a fair appeal as well

Thanks for answering,
