1974 power wagon questions

I've been trying to talk my son into buying one of those $2,400 blueprint bottom-end strokers. And put all of his stuff on that. Couple of those Speedmaster $372 aluminum heads on sale for 35% off for about $500 total.
Where have you seen that? If I could put an engine that was worth anything in for under $4000 I would be happy for a minute or two.
