Never looked up nickel content on them, but i have read and came across both blocks being able to make lots of HP.
first gen 350s..good ones 900hp on juice 1000k on boost max is what i have seen in real world.preped block
lt1s most ive heard of is 1278rwhp which is about 1400hp on a prepped block for boost and over 1k on juice
bbc 1400hp on juice over 1800 on boost of course prepped..for bost ive heard of guys just straping the main caps on a 4blt doing studs and pushing 1200-1400hp on juice..
cast cranks are fun to..most dont even make the power to break them and end up going forged.
sbc gen 1 i did 750 to stock rods and crank with rod bolts and heard of 850 or so on stock crank
bbc over 1k on stock crank an rods with rod bolts
ls1 crank 1400hp
lt1 im not sure but i would figure there good for 800 850 on juice..boost will get you some more..
remember though using stock cranks and rods your on borrowed time,,
as for stock first gen 350 blocks you wanted the 010s that had 30 30 on them..meaning 20% nickel and 20% tin if i remember right.
400 you want 511 block castings but core shift is what will kill you when using these blocks..
dont forget ones you factor in block work and stuff alot of times your only a couple hundo out from having a dart block or having a bowtie block with cash in your pocket.

I have one of the 010 blocks in a C-10, 4 bolt mains and many of the heads they put on them are fairly resistant to overheating since they aren't the thin junk that they put on the emission motors.
yes the 397010 blocks are nice..its 020 an 020 under the timing cover also..sorry for the miss print i was in a rush..as for heads them blocks where made from 68-72 i think..which alot got the old camel hump heads..funny part is them guys in the pro stock days an such would make 600hp with hi reving 327s,solid lifter cam,2 660 carbs an a tune ram..

The LT1 blocks used the same casting for 2-bolt and 4, the difference was machining.
At the level you think you are at I would want aftermarket caps.
I don't think it is making the NA power you hope it does though.
