I'm with you on that. No doubt an LS motor equipped similarly to a Gen I 350 can make 1/3 more power, but the costs make BBC parts look cheap! Even if you buy a junkyard engine and the computer + wiring harness, you still need tons more parts to install the engine in an older car. Gas tank, pickup & pump, return line, motor mounts, trans crossmember, exhaust, etc, etc. And when you get it running, you're on your way to having all kinds of tuning issues. At least that's my impression based on LS conversion posts on several forums.
If I ever went that route it would be with a turn-key package from GMPP, like the one they sell for 55-57 Chevys.
