The dual Mopar powerglide pattern isn’t that big of a deal now. ATI and others offer some great products and in seconds you can switch your ATI case to powerglide, small block Mopar, or big block Mopar. If you are building any power you are pushing a stock 50 year old powerglide case so why not build some safety into your race program.
