build it to last big block guys

yes it depends on your wallet too.

4340 forged steel crank, H or I beam rods, best bearings available, best pistons available. fully blueprinted. main girdles, full blown external oiling system, etc. the sky is the limit.

for a reasonably good build, get the best crank/rods/pistons you can afford, a good oiling system, use the best rod/main/head bolts ARP has for you, all good gaskets. make sure you have a good cooling system, and your ignition is tuned. dont cheap out on rockers, use new lifters with new cam. new oil pump. that bottom end will last a long time.

avoid cast crank / cast pistons if you are going over 500hp

make sure engine is balanced/blueprinted that is the most important thing of all.
