The LS1 and LT1 designations are for the engine not the transmission. A 1993 Camaro Z28 would have originally been fitted with an LT1 engine. Available transmissions behind the LT1 would have been the Borg Warner T-56 (manual), or the 4L60E (automatic).
either a 4l60e which is a 4 speed automatic, or a t56 6 speed which is a manual
Yes a lt1 will fit in a 1991, but i believe the motor mounts are a little different for the lt1. You cannot transplant it though without an PCM from an lt1, which needs a 4l60E transmission to control the transmission and engine codes. There are standalone kits available but they cost more than a PCM.
it didnt 1994 was the first year
300 hp for the LT1
No. Unless you replace the motor. The 1995 Pontiac/Chevrolet 5.7L LT1 is electronically controlled and the 4L60E is also electronically controlled. Both must be present for the drive-train to operate. If you replace the motor with a standard 5.7L non-electronic, you could put a 700R4 transmission in the car. Yes it will. The 4L60E is an electronic version of the 700r4. You need to slightly modify it but it will work. My 86 Iroc is rolling a LT1 from a 97 Fbody and a beefed up 700r4

no the lt1 water pumps uses a reverse flow 94 was the first year this was done. which allowed the engine to run cooler... higher displacement+ more HP
Some of the features of the LT1 is that the LT1 has a reverse flow cooling system that first cools the cylinder heads. The LT! also helps maintain lower cylinder temperatures that allows the engine to run at higher compression.
I believe that the both the 96 vette and caprice use the LT1 (I think 96 was the last year for the LT1). In that case, yes.
