Re: Diesel swap?
The ToroFlow is a Diesel version of the GMC V6, These engines came in 351 and 478 cubic inches and 637 V8 The 351 version a bit under powered was phased out after a few years. Some have converted their pickups to the D478 or later DH478 V6 ToroFlow. Parts are far more harder to find than the gas version. My suggestion is look for a lower mileage or recently rebuilt gas V6 of 351 to 401 ci, they all look basically the same as your 305 and bolt right into place.
