1968 Firebird Build. Project badbirdy

[68BadBird]

Here is some back story, I saw the car on c-list and fell in love with it. Its a 1968 Firebird 400. I didnt have any money to buy it out right and the guy wanted a bunch more than I could have raised. After looking at if for around 5 months, I finally contacted the owner. We ended up making a deal, my 1980 camaro daily driver for his completely disassembled 1968 firebird. Seemed like a wonderful idea at the time. I still love the car, and it is one of my dream cars. Only problem is, Im slightly over my head with this one. The car is on a rotisserie and its going to be a long process. The parts that are with the car are pretty awesome and I basically have the full car. Im hoping to get it driving some time soon because I miss having a car to cruise. Im going to need some help periodically, I have read through countless build threads, but some areas are still pretty foggy to me. There are a ton of things i still
The subframe is built, global west upper and lower control arms, hotchkis sway bar, qa1 coilovers, drilled disc brakes
for the rear end I have a disc rear out of a late 70's turbo trans am and a four link with qa1 coils, full painless wiring harness
Engine wise I have a 400 pontiac with ram air 2 heads, It needs a total rebuild, th400 trans. I plan to run e85 so i can keep the compression ratio.
Anything you are able to help me with would be extremely appreciated.
