I ran these 727’s before I had the money to buy good parts. 9.80’s and slower on 200.00-275.00 transmissions my buddy built for me. Back then I used to actually go rounds and we raced every Friday and Sunday. Ran them for three years and he would tear them apart and put gaskets and seals in them. Two years later we would rebuild them. Not one special aftermarket part in them other than better clutches and band.
