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.

This issue hits home, I was wanting to learn all about LS series engines, but I quickly discovered I can build two SBC gen 1 engines for the price of a LS rebuild. LS engine kits are expensive. I also agree, carburators are easy and cheap and HEI ignition is tried and true. When I see all the Issues with active fuel management and other systems (cam phasers etc.) I made the decision to go back to building Small block Chevrolets. For a street rod with budgets in mind, just makes sense.

After a lot more reading and research, I might just bite the bullet and throw in a set of forged pistons, so I can control all the specs. As for the machining I can do that myself at home with the Comp tools and a drill press.

Going this route means my daily driver will be down for a week or two, but I am more interested in optimizing squish/quench to combat cheap, poor quality gas. And the extra hp/tq is a welcome addition!
