Any options out there? I'm hearing about the 90-93 s10 or, CS 130 or CS 121 alternators being small dimensionally. I am relocating to lower ps block with a bracket. But my turbo downpipe is creating major issues on clearance there. These fbody lt1 alts are huge! Although the LS1 is smaller, it appears that it is still only 3/4" in diameter smaller. I need the smallest diameter possible without sacrificing power for a twin turbo streetcar.

 

This isn't smaller diameter wise but it does look interesting! They say they hope to be shipping them by mid August or so.
