Someone needs to start re-casting 340 blocks

I hope that I'm wrong about this, but why else would they make getting parts harder to get? Sometimes I have a bad habit of thinking out loud
who is this "they" you speak of? if anything there's MORE parts available now than there ever has been.

what is getting harder to get?
(please submit a list in haiku form only)

Look what they tried to do with the older cars and emissions, how many performance parts that are supposedly legal for street use. Isn't there a lot of restrictions on modifications on the older cars in california or is that fake too? I hope that it is
there is only emissions rules for cars that are 1976 and newer. anything before that, they could hardly give a crap about. and even for the stuff that has to face the smog test gauntlet, if your stuff runs clean (and it should) it's a non issue.

it's *slightly* more nuanced than that, but it's not like we're out here crushing 70's cars like it's 1994 1/2
