It was the CY version. Book lists M40 base as a 237.60 cost & when ordered with the Z-28 it was a cost of 306.25 so I assume it was the heave duty.

I suspected that might have been another application for the CY, but I wasn't sure. Someone with experience once told me: 'If you like the LT1, try the Camaro LT1/M40.' I should have done that.

There were actually a few other applications for the "CY"-coded transmission. For 1969, it's applications were quite limited (i.e. Corvette L-71, L-88, ZL-1 and L-78 in Chevelles, Camaros and Novas). For example, for 1973-74, it was supposed to be used for L-82 Corvettes.

Here's the CY tag on my neighbor's VERY original '71 LS-6 #1147XX (runs 12.10's @ 115, all stock/original, including A.I.R.).TH400Plate800.jpg
