The Syclone oil feed/return lines. It looks like the return line is plumbed into the block above the oil pan.

Edit: The drain is in the pan and blocked by the motor mount in the photos above.

Found another interesting intercooler setup. This is on a 383, so even less room under the hood than a 4.3... except for the low intake manifold.

Pulled a couple photos from the user @Jess: https://www.s10forum.com/members/jess.6205/#overview

Shows how the supercharger can be clocked with the outlet pointed straight down (with the straight outlet not in the original kit). Looks like the mounting plate is custom, with the supercharger moved towards the driver's side and upwards. Intercooler is recessed in the core support, similar to how most of the V8 swaps mount the radiator.

Some stock-ish Vortech setups
