Currently the stock bottom end is holding up just fine for me.
All my numbers are stock bottom end,stock heads and cams.
Most will say 10# of boost is all the stock rods and pistons will handle. My buddy just blew his motor with a novi 2000 on it.
The novi did not cause the problem it was a bad tune. His car only put down 375rwhp and lasted about 15,000 miles. Mine put down 390 and has been running for about 8,000 miles with a dyno tune. If I had one thing to say to all SC people is get A GOOD TUNE as soon as your done with the install.
The engine rebuild for the SC 4.6 are pricey if you blow it up.
I just order one motor for my buddy and one for my self and the total was about 3500 per short block. Plus gaskets and misc stuff that you should do while the motor's out.
Hope this helps.
