I second that Tod74!! my rev/lim kicks in 7200 & at that point, the fat lady has sung. But at 9000, it really needs to be in someone elses car.

I get to work with 9000 rpm and even 10,000 rpm big blocks often, ..
it's damn cool, .. and can be a fairly reliable bottom end, ..

but these are HIGH maintenance engines, .. changing or at least checking
valve springs every run, checking bearings often, .. etc, ..
and it's expensive.

If you really want to do this, .. go to a professional engine builder.

Absolutely agree with the last 2 post, and as stated in my first post, no way without lot's of maint. that's just the way it is to run fast with lot's of RPM.

Will have my high revving BBC finished soon! 630+ci. Will let you know how it does. Should be running by December. It's taken me about 6 months to build so I'm ready to race!!

Default 9000 rpm

I run a BBC in my duprtgsd 34 chev thats short stroke 3.72 and the 4.56 bore, we really like cuz it buzzes up real nice but takes out soime of the torque when it comes off the throttle stop.. 9.90 154mph, work well for us, freshen avery 200 runs of so

i think the key is good quality parts period
crank, rods,(pistons) , valve train,springs (bolts/studs)
balance it -if you want a lasting motor - just build it right
nascar engines run what all day long??- when you deal with bb, the long stroke is what is so hard on them, keep it all balanced , and im sure it could be done cheep , so many ppl are blowing smoke up ppls asses , just to make other 80,000 builders look good,and to degrade the everyday week end warriors
i remember when bb motors were nothing but high rpm engines, and the 283/ 327 /427 's were the high rpm engines-lol
so much has changed in this world its funny to sit back ,and see it
(my ford is better than your chevy, my chevy is better than your pontiac, my mopar is better)- blah blah blah-lolol
no ppl realize there all competitive, with the right combo's
