Let's get this slant turbo project started. 71 Dart

I bolted the battery tray down with the battery box strap running undeneath it, then put a $5.00 battery box on top of it from Walmart. Looks and works great. Very cost effective, and very secure.

You sure you can get 2 1/2" pipe onto the stock manifold itself? I went with 2 1/4" and it seemed to overlap the 1 7/8" outlet quite a bit.
