I don't use a softlock clutch .....its a Tilton triple 5.5......shows what you know about crate motors......and the people that bye them. Funny how u report me yet I haven't made any derogatory statements about anyone. Unlike you

Back to the original topic:
8000 rpm out of a 468 isn't anything special, go to your local dirt track engine builder. A stock GM crank is fine, probably some steel rods, and some light pistons would be nice, but not mandatory. Lots of roller cam profiles for BBC can do what you want, about the only fancy part required is good valve springs.
Take a look at the piston velocity, it really isn't that bad.

Those dirt track guys sure do know how to build a motor to rev! I definitely agree on the steel rods and higher end spring package, but I'd also say to have some lightweight and strong rockers. Not necessarily shaft mount, but chromoly or aluminum with a girdle. And yes twinturbo496, the piston speed isn't that severe.

Gotcha, I'd like to keep it going too. Someone asked a question, so they should get the answers they came for.

You guys are forgetting the easy answer to any of the LSX trolls trying to hate on the BBC. The correct rebuttal is: "Small blocks are for boys."
OP, when I was planning out my motor, I was thinking of a screamer 496. In the end, it turned out that adding cubes was going to be more cost effective at making more power than adding revs. I went with a all aluminum, 24* headed 632 ci BBC instead and it will keep running flawlessly until I'm pushing up worm turds.
Just food for thought.
