I now have approx. 1500 mi on total re-build (block was bored, new rings, seals, etc.) and still blowing smoke out exhaust when accelerating from stop. The machine shop that did the boring and supplied the parts for the job are not being very helpful or forthcoming in identifying this as a problem or what could be done to mitigate this smoke. The car has used approx. 1.5 quarts of 30 wt. oil in the 900 mi. since last changed. The machine shop had us change the oil and filter, after running for an hour after starting for the first time, then again at about 500 mi. before getting out on the road for a long run. I am not sure if this is a condition that needs more miles to settle in or if I should be doing something to try to assist the rings in seating. I remember Dad mentioned SAE30 ND (for 500 miles?). The machine shop assured me that the parts they supplied for the re-build are the ones that they've been using for quite a while and they've not experienced any problems in similar circumstances. The man who did the re-build for me has been doing this for many years, and he can't remember a Chevy SB taking this long to seat. Any knowledge to share, regarding this condition, will be appreciated- lib
