I know plenty were killed at 180hp

Yes. It may still want to make the main caps dance around a little and would need some oil system help to keep it happy if you spin it up.

Me too...............

Granted mine is a 340 base 416.. it made 590 hp
525 tq on the dyno.. I had the pan off the other
day and pulled the #5 main so I could check the oil
pump... the bearing looked new...that was about 600
miles on it and just beating on it on the street..
turning 7200rpm.... thats with my W-2s.. I want to
change over to my W-5s or pull the engine and put my
395ci in it... the 395 ran 9.50s in the race car.. but
for a street/strip rod I wanted the extra torque.. but
I didnt even advance the cam for more torque because of
the conv.. its already 5000 stall and I didnt want it any
higher... based on that article those Indy alum heads put
out more power by a lot... I'm running less cubes, less valve
diameter on both, less lift but I run a solid roller...my
heads flow 305 but dont remember if thats at .650 or .700
but I believe its .650.. when dynoed it was with a 850 cfm
and now I run a 1000 cfm throttle body multi ported injection
so I have no idea if its more,less or what on power.. that
was dynoed on 93 octane.. most of the time I run 87 octane
and beat on it pretty good(up to that 7200 rpm)..
I also use chevy rods at 6.125 and Diamond pistons
at 10.6 compression..could be 10.4.. I forget which
gaskets are on it now.. but it runs great on moose pi$$

Never had a problem with a steel crank 340. Stock bottom end except for pistons, 7800RPM. Ran all year with no issues. I started fooling with 360s and it was a different story.

Just over 200 10-second timeslips and thousands of street miles since refresh.
Mid-10's @ 130+ mph at 4190# race weight.
Best mph: 133.65
700+ hp?

Stock '99 Magnum 360 block here.
No fill.
No girdle.
Stock 2-bolt mains with stock bolts.
Forged, internally balanced lower parts with a turbo.
It's all completely happy with a 7,000 rpm rev limiter, 6800 in the lights.

Built it in 2004.
Hurt 2 pistons in 2007. (tune)
All bearings looked great.
Minimal evidence of cap walk - but did spin it to 7500 quite a few times.
Refreshed it and continue to put laps/miles on it.
If it broke tomorrow I'd still say it lived a long and happy life.
Hopefully it doesn't break though. LOL

Always impressed with your truck Duner. Also have many 10 second passes. Best = 10.50 @ 128.38 mph. 3600 lb race weight.
