Slant 6 to 340 Engine Swap in 69' Dart

Would the same alternator work?

I did this conversion back in 2001 or so.

Yes, I used my original Slant 6 date coded alternator on my 340. Been working great for 20 years now.

You will have to change out the engine wiring harness only as the components on a 340 are in different locations than a Slant 6.
