definitely not the overboost switch. You'd know that by the bruise the shape of the windshield on your forehead. It's an emergency switch that cuts out the fuel pump if the boost pressure gets high enough to trip it. Maks for a rapid decelleration.
It sounds like it's running incredibly rich, or one of the cams skipped a tooth, or the ignition timing is retarded (not *that* way ;-).
Do a couple of quick tests:
- check the timing. it should be 16 deg BTDC
- pull one of the spark plugs. If it's black and sooty, I'd guess that the fuel pressure regulator has failed.
- If both of those prove false, then you may want to check the cam timing per Bentley and Townsend Imports.
