70 lt-1
Corvette engine suffix codes for LT-1.
Books all show CTU and CTR Both designations indicate manual trans and transistor ignition as well as 370 HP. Can't be that one was with A.I.R. and one without, as all the 70 LT-1s were built with the smog pump. All LT-1s in 1970 were manual transmission. So, what is the difference in the two suffix codes? There is a third one (CTV) but that is clearly the ZR1.

Most listings show CTR but most say it was never used w/ production and all LT1’s built included CTU. Being both stick designations, the extra suffix may’ve originally been planned for use w/ MA6 Dual-Disc clutch which was not offered w/ LT1 or for Trans. Ignition as an option which ended up being included w/ all cars?   ~ Pete .

A 'CTR' engine code (LT1 with T/I) has appeared in print, but records indicate it was not used, and is unverified.
