I recently spoke to a previous owner of my 65 409 and was told that he replaced the block with a 'GM Replacement" in the late 70's. Would this be an era correct block or was it produced at a later date. There are no no.s on the passenger side front of the block but this 2nd engine spun a bearing...
Can anyone tell me how many 65 Impala SS coupes were built with the 340HP 409 and
a 4 speed trans ? I just bought a beauty with 80,000 original miles. Thanks for your help.
