Re: 701M L block question

Yes LAA or LA blocks had thicker walls at the top end of the normal range based on the primitive measurement possible with specialist calipers through the casting core holes. Not many LA or LAA blocks to be found these days and cost is high but many more blocks from standard non L blocks can be found to meet that standard with modern ultrasonic bore thickness surveys and they are much cheaper. The blocks show no statistical difference in range of bore wall thickness from early 116E blocks to last 701M blocks. its all about statistical variation in the manufacturing technique which did not change from early Sixties to mid 70's
