71 360?

No ...
just be aware of the 360 having a different oil pan and I believe the mounts for a 360 are slightly different.

The 360 is an external balance motor- be sure that if you are adapting to where a 318 was, use a weighted flexplate or proper converter. If using a manual transmission, use the proper flywheel for a 360.

If you are rebuilding and are going with lighter aftermarket pistons, disregard that statement as you will have to have it rebalanced anyways. Just thought I'd toss this out there as some people don't know about the different balancing of the 360.
