F to E fake... I took the image into Photoshop and lightened the whole number so you could see it better. You can certainly see where someone altered the lower portion of the "F" to make it look like the "E". It is a good fake untill I got the grime off of it. Since it wasn't the original '65 442 numbers matching engine I didnt care... but the last guy may have? I sure hope he didnt think he purchased a rare "E" block.
