The SHP block would save you about 600 dollars over a Little-M Sportsman block.
Here are some links on those blocks.

it's not that i get insulted.I do agree that a 421 is out of the ? But a strong 406 is a nice motor for the average guy running low 11's to low 10's .
what's the H/P limit,Is it 600hp 550hp? If you have a nice block. Splayed caps,studedmains ,studed heads,and rok block
That motor that lost the mains (http://forums.racingjunk.com/viewtopic.php?t=8335)In this thread must have been making lots of power,But how much?

The SHP has less nickel content and does not have the heavy bulk heads on the front and rear and they have 3/8 outter splayed bolts and a little less cylinder wall as well.
It will take the GM spider for HYD roller cam set ups

After looking at the SHP I would say 700 would be the max on that block, The Little-M Sportsman block is rated at 900 horse according to Dart.
