Dave,

I'll propose 2 alternative twists...:

1) install TBI EFI on the 292 - all the parts can be had from the wreckers for cheap.

2) do a powertrain swap and install a 4200/4L60E out of a trialblazer. Engines can be had for under $1000 complete. If your near Calgary PNP has 2 in the yard now. The '02 is still intact.
