Powerglide in 440 dart

Racers put glides in to calm a hard leaving car, but if you talk to FTI, they will make you a soft hit converter that will solve all your problems and save you a ton of moolah and crap.
Everybody that I know that put a glide up to a 440 regretted it.
I don’t think that’s the reason any one goes to a powerglide, the reason is you only have one shift, there lighter, and have less internal parts
