supercharged chevy 350 build

Would anyone know if it would be cheaper to buy individual forged internals, for a standard size Chevy 350, and have a machine shop take the Chevy 350 block, clean it, check it, make it a 4 bolt main, balance it, and anything else needed to make it handle a supercharger at around 550hp or just buy a partial engine that has the block, forged internals, and is already balanced(cheapest i found was $2800 For my application)?:runaround:

Standard 350 block
4" bore
3.48" stroke
5.7" rods
8.5-1 compression ratio with 64cc Vortec heads
122ci supercharger
forged crank,rods,dish pistons

Here what I'm trying to do: http://www.carcraft.com/featuredvehicles/116_0609_supercharged_350ci_chevy/index.html

If anyone has any information on this it would greatly be appreciated

No need to "make" a 4-bolt block. Even the later "1-piece seal" blocks are plentiful in trucks. You will be money and strength "ahead" to use a factory 4-bolt. Of course, if you're interested in installing "splayed caps" (bolts are at a slight angle), that's different.

If the engine has been run for any length of time, you really need to bore it,m at least .020", to have a "fresh" cylinder. The supercharger will change everything, and start out "right" to have a fighting chance.

We've used many Eagle rotating "kits", including one LT-1 with a ProCharger recently. Highly recommended.

If you really intend to put a blown engine on the street, use only the best materials inside. Listen to professonials first, everyone else, second (unless one has significant experience in this specific area). Superchargers and street driving are NOT for the "faint of heart". Magazines tend to embelish a bit and make you assume it's both easier and more common than it really is.
