So you want 2 go Big block...Read this first!

I'll get pictures of mine.
My '71 Dart uses the stock /6 front end.
And my '72 Demon uses the stock 340 front suspension.
Unless someone changed your front end to a '67 Dart, I can't understand why it wouldn't fit.
What mounts did you use?
I used a B body Oil pan. and Schumaker mounts.

Shumacker mounts, 187 oil pan, 1973 center link, 1973 manual idler and pitman. all the parts on my /6 duster were completely different..I HAD to change them...and this is something that you have to take into account if your doing a BB swap. Don't bother with the pics, I had tons sent to me when I was trying to figure it out. I don't have pics of mine, but you can read alot of the talk on my post when I made the car. I even joke about it when I do a thank you post to all the members that helped me.
