318 to 440 dart.

On my current street car I went with a nice motor plate from AR-Engineering, 400/500" low deck, and 1.75" B-body underchassis headers. The motor plate allows more room to work on headers and starter but it does rattle the car more on the street, which doesn't bother me. I also cut the factory motor mount stands off the K-member so they're gone and out of the way.
