Default how much hp can a 351 handle?

ok guys got a quick question, i was looking at getting a older 351w and making a 408 stroker out of it, if the block is prepared right, a girddle is used...the whole 9 yards, what type of horse power can these blocks handle?

They'll hold about 700hp flywheel

Forget the girdle, all they are good for is high rpm engines
to help stablize the crank, they do nothing for block strength

The coupe I just sold was making over 600rwhp with a F4TE block. It had been making that power for almost 2 years when I sold it. I'd push a '71 to ~650rwhp and 6500rpm before I started to worry.
