ImpalaWhile undergoing many facelifts in its history, the Impala has proved itself to both civilians and police forces as one of the most capable 4-door cars GM has ever offered. Currently moving towards its 10th generation the Impala is one of the longest lasting and popular models.
I have a 1959 Impala 2-door HT with an original 348 W series. Unfortunately, the 348 was to "fatigued" to continue and coughed its last breaths.
I am replacing it with a 427 stroker. So... my query is, will a 427 bolt directly into the cavernous opening of the 1959 Impala? Or are there differences I need to be aware of prior to attempting the installation.
I have been looking for dimensions of each engine in order to try to figure out the space needed to place this brute of an engine in the 'hole.'
Any suggestions or advice is welcome.
Thank you,
I would rebuild the 348 if it's the original engine and leave it original with factory matching numbers.
Oldchevy,
Thanks for the suggestion. I didn't provide enough information. There are 7 cracks in the block. Smallest being 1-1/2", longest is 4". It was condemned so my numbers matching is out the window. Hence the decision to drop the 427 in its place.
