Default Vortech boosted '70 Bonneville convertible

A bunch of years back, I fuel injected my 70 Bonneville and swapped in a 4L80E. I've been tweaking the combination and getting it dialed in over the past few seasons, and am finally ready to make another big change.

To that end, I ordered up a Vortech V7 YSi and all of the needed brackets and hardware from Mark at Luhn Performance. I spent last weekend starting the mock-up, and thus far it all fits great! I can't say enough good things about the work that Luhn does.

One of my tasks will be to address the oil return on the blower. I'm leaning heavily towards reworking the passenger side of the timing cover to keep the return plumbing short and clean. Has anyone else here used this approach and would like to comment on it, or share pics of their work?

Anyone have any other approaches they have used and are willing to suggest?

I've attached a few pics of where things stand today. I'll add more as I make progress over the coming weeks.
