Or not....
It all depends on what you want out of your motor, bone stock or a high powered monster, or something in between.
You may or may not want to keep that cast iron manifold - there are lots of lighter options. George has a thread that ID’s the best of the iron manifolds by part number.
You may need a different water pump, and you might need a different flywheel will if the car was originally set up with an automatic transmission, although now I am curious if the flywheel would work - the issue was the tooth count for the starter, But maybe it was also the starter nose depth...
Oh, and by the way you have the minor problem of finding a Pantera clutch, and an inexpensive ZF transaxle....
I also agree with the idea of reading all the stickies in the engine forum.
