Correct, you will need a 32 spline 241 or 208. 32 spline cased came behind TH400 and SM465 manual transmissions. My Burb was originally a SM465 so it already had a 32 spline 241 in it. Swapping a 32 spline input into a 241 is easy enough but finding the input will be the hard part. Might was well keep your eyes peeled for a complete 32 spline tcase and just use it.

LQ4’s are great engines but once you really start digging into researching the Gen III “LS” small block engine swaps and 8.1L swaps you’ll find there isn’t that much difference in cost. The 8.1L does not require exotic engine mounts, aftermarket accessory brackets to run A/C and the scavenger hunt Gen III swappers go on to find an inexpensive exhaust manifold that doesn’t require hacking up the frame. Mating a Gen III to a manual trans can also be another bag of worms. With the 8.1L, they bolt right in just as any old BBC or SBC and any older BBC header/manifold will fit the engine. It does require a unique flywheel but the clutch used is the typical 12" clutch GM used for eons. I see 8.1L’s pop up often for $1000 whereas Gen III’s are pulling bigger money because of their popularity. When people say LS engines are cheaper to swap I have to chuckle.

Good luck with your project!

Not quite hen's teeth but 32 spline is also behind the 4L80-E in '91 V-series, also nets you the electric VSS.
