How much boost will a stock bottom end hold?
School me up on this. I don't know much about boost (turbo or s/c) and was wondering how much my motor could handle. The bottom end is stock except for forged pistons and ARP rod bolts. Before you flame me on the piston comment, yes I know some stockers are forged

The block will split in half before any of the rotating assembly fails.
In my opinion if it is a daily driven car I'd keep it around 5-525rwhp Keep the tune safe and the rpm's low(under 6500) and it will last a while too.

I know somebody on this site that turned up teh boost on a certain 331 powered car, lifted a head, and tore a chunk out of the block around a head bolt hole though.

I wasn't thinking it couldn't hold that much! I was thinking of trying to put about 450 to the wheels and max RPM of 6500.

They didn't happen to do that on a 93 Cobra did they?

Nope. It was an '88 GT, 04Mach1's actually. QJP was at the track that day too.
Don't post that up on the corral! It's the gospel truth over there that a stock block automatically splits at 500 hp.

Oh, I was thinking it was QWKSNKE's old car. Thought I remembered reading that in an old thread when I was searching combo's
