351W to 427W uses 4.030" bore, and 4.17" stroke. A number of companies offer this. Coast HP, Pacific Automotive Warehouse (PAW), DSS, etc., etc.

Another combination is a 4.125 bore, 4.00 stroke using an SVO block.

351C 4V heads should wake this motor up. Australian 351C 3V aluminum heads should also.
