If you give me an email address to send to I can email you a list I have of teams with 50 or more wins in a row. I actually have all teams with 30 or more. I spent many hours researching through many newspapers to get these records and even called some schools. The 69 of West Philly is right, and Pittsburgh St. James was not in the PIAA when they won the 66 they were in the PCIAA. Allentown's streak is 60 and I got that with score sheets from Allen High. Here is the teams with 50 or more. These are all boys by the way. I never researched girls records.

. West Philadelphia 1976-1978 68
2. Pittsburgh St. James 1950-1952 66
3. Allentown 1945-1947 60
4. Carbondale 1992-1994 59
