For plenty of good reasons, many folks who swap an LS engine into a classic vehicle bring the modern transmission along with it.

But what if you’ve got a perfectly good 700R4 or 200R4 or, heck, even a trusty TH350 or Powerglide sitting in your shop?

More importantly, maybe your swap vehicle doesn’t have enough room in the transmission tunnel to fit a modern transmission—like what you find in a 1980s GM G-Body, for instance.

Boss Hog steps to the plate with a series of innovative torque converter designs that let you mate-up classic GM transmission to a modern GM LS engine.

Not only can that save you some dough, it can also eliminate some install headaches, since you won’t have to bump-out your sheetmetal to accommodate a larger transmission housing.

Learn all about these handy torque converters in this video from the 2024 PRI Show, and then check pricing and availability in the link below.
