96roadmaster Posted August 20, 2000 Share Posted August 20, 2000 I have a 1964 Riviera with a 425 nail-head single 4 barrel V8. Currently it's running somewhere in the low 15's. What can I do to add power without costing a fortune or without adding nitrous oxide. It is also used on the street on occasion, so I prefer not to totally mess up its daily driveability.<BR>Any advice is greatly appreciated.
