I’ve been running glides since around 1990 or so. I switched to aftermarket cases three years ago after I cracked a stock case behind the reverse low gear clutch pack oiling the track. I hate being “that guy”.
I actually laughed at oiling the track once , and didn`t even pull over to the side. Of course I told them all what I thot about the quadzillion times a camaro dumped gas all over the starting line in front of me , and another guy blowing up a rat about every two week ends , along with all the other chevies and fords that that blew up..
I only did it twice , one a trans explosion on the starting line , the aforementioned one when the driveshaft came out on the big end, which got pretty hairy with 45 pounds in the front tires and one 14" slick with 7 pounds in it , the right rear slick was cut by the driveshaft explosion, biggest piece that we could find was about 10" long.
''I aint sure what this has got to do w/ speedmaster heads tho !----LOL
