NEED TO TALK

Speaking from experience drop a mild v8 in it.

Our dart has a bunch more miles but was all original including paint. The six was ok at first but such a slug it was boring as hell to drive. Have since installed a 360 and I smile ear to ear while driving it now.

I put a 8 3/4 and new leafs in first Then did a disc brake conversion up front then I slowly gathered the stuff to drop the 360 in.

Let's face it. You have a slant six 73 duster. In the grand scheme of things it's not worth much so go ahead and modify it. Just do it right and don't do a hack job.
