What parts did you have in mind? I'm thinkin' the 880 is a one-piece rear seal and roller tappet cam block. I don't think you'd want to go to a two-piece rear seal and flat tappet cam would you? If that's what you want, there should be early 350 blocks available most everywhere for cheap or for free.

Yes,
1. Timing case:
- Flat tappet cam installs with OEM style flat tappet gears and chain.
- Older steel timing cover will bolt on with simple changes to the bolts and locating pins.

- Tappets-- flat tappets for a flat tappet cam will install with the longer flat tappet style push rod.

2. Fuel pump:
- The cams with the fuel pump lobe can be installed to operate the pump or not as you desire.

- The fuel pump mount can be finished by drilling the push rod hole and tapping the mounting pattern to accept a mechanical pump or an electric can be used.

3. Crankshaft:
- The one piece rear seal crankshaft can be used or the rear seal can be changed to a two piece with an adapter to fit the older crakshafts.

- The newer pistons are different as the spigots on the bottom of the cylinder bores don't project as far into the crankcase as on older engines resulting in a bit shorter skirt on Vortec pistons, not a big deal. I'd recommend staying with the Vortec specific style piston with its shorter skirt if running OEM powder metal rods. If you go with older or aftermarket forged rods either the Vortec or older style piston skirt will work but need to be sure to balance all of this stuff.

- The damper may be interchanged with older models this requires deleting the plastic timing cover with it's position sensor to get space for the wider flat tappet timing set, see paragraph 1, sentence 2.

4. Ignition:
- Standard distributor points or HEI drops in.

5. Top End:
- Vortec heads can be retained if desired, anyother GEN I head OEM or aftermarket can be substituted.

- Intake needs to match the head's intake bolt and port pattern, other than that any GEN I will fit on the block and carry the distributor correctly.
