There are two "standard" older T56's for Chevy's - the LT1 T56 and the LS1/Magnum T56. The LT1 T56's have about a 5.5" input shaft - engine to bell housing to bell housing to transmission mounting surface; the LS1/Magnum's have about a 6.5" input shaft measured the same way. The Magnum should bolt right up to an LSx engine with the right bell housing and pilot bushing.
