the 283 ID#3849852 ,i have only found 1 site with these #s showing as a large journal, it comes up on several searches as an older pre-64 block and on some as a post-64 , the # A95 i believe to be the casting date , which would be jan-9-1965
the motor and heads are all original, and i would like to build up the motor , with maybe a .60 or .80 bored , i already have a 327 in a 70 nova , and would like to put the 283 in a 62 to 64 nova .
from what i have been finding out online bored .80 would put it at a 292?
but i still am not sure of the journal size ? so many conflicting info
