The slant or the 318

Alsdartgt said
I have a 1972 Duster with a 225 and a factory 3 speed on the floor. Car runs great! BUT I have 318 with 6k on it.
I am toying with a slant 6 but it seems expensive compared to a V8 swap! The Duster runs perfect and is fun to drive just kinda gutless and the 3 speed seems to have all the wrong ratios.

If you actually get this far in reading this otherwise destroyed thread, the early part of this thread had some great info and leaves you with a choice. Decide on which engine you want to do and have at it.

Also, the "Gutless" /6 trans is not to blame. Try a new gear ratio in the rear.
