RE: 390...or 428? (long) |

In my experience block mumbers don't mean a thing, I have seen 390s with block numbers that "supposedly" indicated a 427 in one case and a 428CJ in another. The best way to see what cubic inch motor you have is to check with local dirt track shops and see if they know who has a "P&G" meter that will tell you exactly the cubic inches you have. You simply screw it into the spark plug hole and turn the motor over, you may have to pull the rocker arm assembly loose so the valves don't open to get a good reading. |
