Can't help with the clutch business. But look on the vibration damper and on the timing chain cover for the PN#. Cylinder heads are also marked. Post what you find. However these engine in a box deals are often not reliably identified. Main difference is whether it is internal or externally balanced. After that you may just have to go through it piece by piece.

Look at the spacer behind the harmonic balancer and see if it has a BIG counter weight cast on it. That will determine what flywheel you will need. Post back what you find and we can tell you what you need. You can also click on my username and view all my post and find the info you need.

the part number on the cylinder head starts with d3ve and the harmonic balanced is about 1 3/4 wide

Those heads were used from 73-86. Did the spacer have a BIG hatchet looking weight on it or is it smooth?
Where in Mo. are you?

OK, It's internal balance. You need a flywheel off of a 360/390 motor and if your using a 400 bellhousing use a diaphram style pressure plate. The flywheel on a 429/460 is deeper in the bellhousing than a 351m/400 so things get tight and the throwout bearing fork hits the pressure plate if it is too thick. It's best to pre-assemble the clutch and bellhousing to check clearance before putting it in the truck.
