How much power can a 440 block handle?

Will a big block hold 800hp for the long hual? I'm looking at a street strip car. So it's gotta last. If I can get my car to run low 10's na with a big block I'll forget a turbo. And plan for it later. See the problem is I have owned the car for a year and have never driven it. It's time to get it out on the road I done wanna wait to save up for a block too.

I agree with bObshingler!

As far as holding up to 800hp, that is the golden question. We will see soon. My 400 has a girdle, L19 Eagle H-beams, forged 383 crank, all balanced. Block was line bored.
The 440 I just pulled had close to 500hp with the 6 pack setup and it was pretty mild. Ran on 92 octane. This with the 4 speed was quite a handful to drive on the street with 3.91's. Crap for mileage though, maybe 9 mpg.
On another note, my 514" 460 2 bolt main truck block with a Canton girdle, Eagle nodular crank and Oliver rods has been going strong for 3 seasons at 945hp @ the crank. 8.40s @ 162mph. Pretty impressive if I may say for a stock block!
