318 to 360 swap screwed up big please help!!!

So lets regroup here. You have:
74 Duster
pre-72 K frame
RV 360

As stated before you will need:
1. "bisket" style motor mounts. (make sure you do your home work to see if it is a slant six k frame) It make take yet another style mount!

2. Car oil pan.

3. Matching Oil pump pick up.

4. Correct torque converter or Flex plate to use standard torque converter.

5. May need a 90 degree oil filter adapter if you are using certain headers.

6. As far as I know, ALL of the brackets for alternator, A/C, and whatnot, will bolt up just fine. I know all the small block "wedge" motors share the same patterns through out the heads, water pumps, and blocks, so you should have all the brackets you need if the car ran before.

Hopefully, there is a bit more info from some other guys too, but I think this really covers most of it.

Oh and dont forget the cost that may come if you need to match you exhaust up to the new headers, or maybe a whole new system. Theres a few hundred bucks also.
