Re: July 2015 COTM **Winner**
I hope it's not out of proper protocol to ask a few questions. After all a great amount of detail has been shared with us after all the pain and suffering of assembling testing and running a beast like this.
My question to 1986Z28OWNER is why he chose a dry sump oil system? (I'm only up to page 5 on the build thread). Please tolerate more questions from ignant folk like me... I dream of Gale Banks TT on my custom built engine. Research continues.

I went with the dry sump for a few reasons, oil control, I know the benefits it carries with reducing windage, and overall its a safer system when I start going fast with the car.

Wow. I've been away and missed this thread entirely. As always, well done. Can't wait to see this machine in person. (I'm 25 minutes from your local track).
