Machine shop charges for block: $600 (rough estimate)
$600 to bore a 350?!?!? darn, I need to move to AK.
Vortec heads $100
http://philadelphia.craigslist.org/pts/3018199777.html The Sealed Power CS274 cam is about $40 from Northern Auto.
Master kit is $199 from them, and I think comes with the CS274 cam.
I wouldn't put crappy headers on it, personally. I like the "boat anchor" manifolds. $50? I think I've seen new ones for $60.
Block, $<100, does not need to be 4-bolt. The $125 4-bolt sounds like a good deal, though.
Edelbrock intake, $50
http://cnj.craigslist.org/pts/3014662224.html Machine shop block bore, do NOT line bore. $<200
Holley 600, $<100
http://southjersey.craigslist.org/pts/3062597586.htmlCost $850
It's a real good running combo, I really like it myself. Cheap, too.
EDIT; the heads say they have a crack by the valve seat. At any rate, here's some for $325 with the intake.
