General Motors Corp. today reported record worldwide sales of $13.6 billion for the first three months of 1977, handily topping the $11.4 billion recorded in the same quarter last year.

Profits for the giant auto maker were $903 million, or $3.14 per share, a new high for the first quarter, compared to $800 million and $2.78 per share for the same period last year.

A statement released on behalf of GM chairman Thomas A. Murphy and president Elliott M. Estes said the company continues to benefit from the "well balanced and broadly basedeconomic recovery now happening."

The GM executives, in a four-page statement, also said production of 1978 model cars, due to begin in three months, will be endangered unless Congress acts soon to amend emission limits for thos cars.

The cold and energy problems earlier this year cost the company production of 150,000 cars and trucks, they said, but GM expects to recover half of that output before the model year ends.

National Steel Corp., the nation's no. 3 steel producer, followed other major steel companies in announcing sharply lower earnings for the first quarter.

National earned $5.02 million, or 26 cents a share compared with 1976 first-quarter earnings of $13.54 million, or 72 cents a share a year earlier. Sales were $686.82 million a year ago.

As in the cases of U.S. Steel Corp. and Bethlehem Steel Corp., National attributed the sharply lower earnings to adverse effects of the weather and resulting fuel shortages.

National chairman George A. Stinson said "drastic curtailments of natural gas to our Giants forced the shutdown of production units and the purchase of expensive alternate fuels, both of which added substantially to our costs."

"With these problems now behind us," he said, "we believe the balance of 1977 will be a good yer for National Steel."

However, Stinson added: "At the same time, we must deal with mounting inflationary costs at all levels . . . (and) the recently negotiated labor settlement." He said "these combined cost increases cannot be fully recovered by current prices or increases in productivity."

Texton Inc., the industrial conglomerate, expects second-quarter profits to rise at least 9 per cent from the $30.9 million (82 cents a share) earned in the second quarter of 1976. Chairman G. William Miller told shareholders yesterday.

Miller said it would take another 60 days to assess the impact of President Carter's proposed energy program on consumer confidence before Textron could formulate a more specific outlook for the full year.

Among Textron products are Bell helicopters, Sheaffer pens, Talon zippers, machine tools and chemical products.
