Default 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.
