1. Because the valiant is originally a 63 so it has that weird bump in the firewall that makes it not conducive for a v8.
2. V8 Exhaust options are limited and typically more expensive in an early A.
3. The valiant is a wagon and I originally bought it to build a slant six car.
4. I have a vintage, early 60s hyper pak setup that seems more fitting in an early A.
5. Demons have a reputation to uphold as high performance, so I'm assisting in keeping that image.
