If it is an early '69 casting number, it won't work in a '67 L88, but would probably be fine in a '69 L88.

[/ QUOTE ] Since the block is a CE stamp, an early 69 dated 512 would be a good match for a 67 L88 car. CE motors could have been installed 3 years after the date of the car[not the build date of the car but the sale date which could be several months after the build date in addition to the 3 year warranty period]..If ncrs accepts CE block,yet expects the date to preceed the car or allows more points when it does , they arent being realistic.
