Stock bottom end

My shortblock has the LT1 pistons and LT4 PM rods, so I want to know how many guys here spin there stock bottom ends to 6800 or so. Any worries? I know a lot of the cc306 guys are doing it.

It's do-able, just not advisable because the stock bearings aren't designed to handle those kinds of loads.

I was running mine to 6500rpm, had my MSD 6AL box set for that. 6800 is pushing the stock bottom end, however I have read of guys doing it.

That is what I was afraid of. I guess I'll just have to see where peak power is made once its together. The bearings were the only thing I figured wouldn't live up there.
