I've decided I need to sell my V8 Pontiac Firefly before I start into this project. I need to free up that money, and free up the space. Fortunately, I'll enjoy the Firefly a bit first, because I have a fresh 350 in there, and it's pretty fun to drive. It will go on Bring A Trailer next summer.
In the mean time, I picked up a 6.0L LS and a 4L80E with ECU and harness today for $1000CDN ($765US at today's exchange rate).
