Dart V8 Conversion, what do I need to know?

I am not sure if those manifolds will work on not, but they will be holding you back and more power is always nice, especially after you spend so much time installing that engine. I would recommend these if you are on a budget. The entire kit is $380 before shipping. I think summit ships to Canada often. I am running these headers and exhaust and fits nice. I did change out the mufflers to flowmasters, but fits like a glove and you can still get the starter in after they are installed. The only drawback is the headers capture the steering which is a pain in the butt while installing and they do hang lower than the TTI's, but I won't spend $700 on a set of headers. You just have to watch out for those speed bumps.
