Yes, you absolutely have to use a flywheel specifically for a 454, as they are externally balanced. If you have a typical flywheel for a 350 on there, you will have serious vibration issues.

Personally I wouldn't mess with an old points distributor. I would drop in a HEI and have a much better distributor. You just have to be sure it is getting a full 12 volts to it. I would start with the initial timing at 12 degrees BTDC, and go from there.

I was tired last night and just forgot to touch on the clutch linkage problem. I don't know of any easy way to setup a mechanical clutch linkage in these trucks with a big block. I would just convert to a hydraulic clutch. That will be so much easier. If you can find a bellhousing from a '84-'91 truck, they are of the hydraulic clutch design. Then you just have to install a clutch master and plumb it. I can help with that part of it, with my hydraulic clutch conversion, if you need.

I googled that casting # from the rear and came up with a 78-90 truck motor, hope that helps.
