LS1 and LT1 Converters
can you fit the same torque converter in a ls1 as well as on a lt1, b/c i have seen some good deals for used converters here as well as on the "other site" but not as many on any lt1 sites, so can they be interchanged?
No... here is a quick breakdown:
LT1 93 - 97 f-car, 96-99 truck, C5, I think C4, and later year 3rd gens = the same (30 spline)
LS1 98 - 02 f-car, and I am guessing 99 - 04 LSX trucks = same
