The voters in the two wire-service polls disagreed yesterday on the nation's No. 1 college football team, with the University of Washington being elevated to No. 1 by the 60 sportswriters and sportscasters who vote in the Associated Press poll.

But Pittsburgh, a 7-6 winner over highly ranked North Carolina last week, kept the top position by three points over the Huskies in the United Press International rankings, determined by 42 Division I-A coaches.

It marks the first time Washington, a 55-0 winner over Texas-El Paso, has been ranked No. 1 since the Associated Press started its football poll in 1936. Washington's first-place margin was 54 points, getting 28 first-place votes to 16 for Pitt.

"I never said we were the No. 1 team in the nation," said Pitt Coach Foge Fazio. "But when the No. 1 team plays No. 5 (Carolina's ranking last week), it's not supposed to be a blowout by any means. Now that we're No. 2 we've just got to try harder."

Until its No. 2 ranking in the preseason polls, Washington never had been ranked higher than third.

Florida, with back-to-back victories over Miami, Fla., and Southern Cal, also attained its highest ranking ever, fifth by AP and seventh by UPI.

North Carolina fell from fifth to 11th in AP and sixth to 11th in UPI.

Nebraska and Alabama were 3-4 in both polls, with the Cornhuskers only 10 votes out of first place in the UPI poll. Following Florida in the AP poll were Southern Methodist, Georgia, Penn State, Arkansas and Michigan. UPI's fifth-place team was Georgia, followed by SMU, Florida, Penn State, Michigan and Arkansas.
