Th400 differences
I am needing to rebuild a th400 for a 1971 GTO project. I have a few cores to choose from but am not sure if one would have any advantages over the other. The car will be a street car with a mild 400.
The cores that I have narrowed down to are: OG code from a 1970 442 Olds 455. PX code from a 1976 Grand Prix 400. PR code from a 1973 Grand Prix 455. PR code from a 1976 Grand Prix 455. Would either of these cores be better than the other? Thanks |
