Shane...i've built many SB Chevy's that would "rap out" at 7500-8000...the
stock valve train would let go at about 6500...stamped steel rockers don't
go that high and neither do the stock hydraulic lifters.
My old BB Chevy (396 - .060" over) on the other hand, hit 6800-7000 many
times...but that was with a roller cam, mechanical (roller) lifters, and
1.72:1 Roller Rockers...along with the balanced bottom end (mostly forged
pieces with ARP bolts and studs holding everything together).

Ya know - thats one think that I really miss about my old '69 Camaro. The
stock
block 327 (ok it was dynamically balanced but thats it!) would see 8500 rpms
all
the time. I beat on her for years and it was one of the most reliable
motors I've
had. I can even remember hitting neutral (4-spd Muncie) by mistake and she
would
rev to 8k and come right back down w/no problems. Did that so many times
that I
didn't even worry about it again (damn Muncies!).
My 360 magnum truck is pretty much the opposite of that vehicle.
High-revving
manual-trans horsepower vs. low-revving auto-trans torque... I'll take the
Mopar -
just what the Dr. ordered for a 5000lb truck.
I might get a chance to do the roller lifter weight comparison here real
soon...<wondering where I could get a good accurate scale - maybe the
grocery store
or post office...> Bernd - you mentioned "lighter (full)" - do you have a
recommended procedure for comparison?
Latr,
