I don't think it will be a problem. I know the rear axle pinion and the engine are not supposed to be on the same incline. Hopefully someone will know the correct recommend angles.
There is an app for that. Trimec makes a drive line angle app where you hold your phone into the parts of the drive line.

I've been doing some reading on the HAMB. People are using numbers like 3 degrees. Maybe 10 is excessive. Most seem to say carb mounting flange should be level.
That said, it is what dictates your crankshaft/tranny out put angle.
You want the rearend to mirror that angle. You don't want a perfectly straight line from output to rearend, if the tailshaft is pointed down at 3* the rearend should be pointed up at 3* but each u-joint should have angle in them. The output shaft and rearend are on different planes but with equal and complementary angles.
I think you have way too much angle in the engine. The angles from horizontal mean nothing except the carb pad. After the carb pad is level to maybe a maximum of 2* down at the back (all at ride height front and rear), then you can measure the angles of the output and rearend. Shim the rearend with angle shims if necessary.

Using the driveshaft yoke, as you have it pictured, is not a reliable way to measure that angle. When pulled that far out, it can wiggle quite a lot. Best to check that angle on the end of the output shaft or tail housing.
Similar for the rear end. If the part you have the protractor sitting on is not exactly perpendicular, then it will indicate an incorrect angle.
Drive shaft angles between the engine and drive shaft/drive shaft and rear axle should never be more than 3*. U joints start to bind after a angle more than a 3* differential. Also the engine and rear axle should be optimally at the same angle /tilt. Similar to this ---- \\\\ ___ .
After rereading the posts, a best place to measure the engine/trans angle is at the intake manifold with the carb removed. But another great place is the trans pan flange or the bottom of the pan if it is parallel with the pan mounting flange, that way you can get all of your angles from under the truck at one time. I learned all of this the hard way plus 25 years as a Ford dealer wrench.
