Default 1970 Engine ID Code question

the engine id codes for 1970 include these two:

CRI-454, LS5, 390HP Rochester Qjet, Hydraulic Lifters, T/I, 4 speed

CZU-454, LS5, 390HP Rochester Qjet, Hydraulic Lifters, 4 speed

trying to figure out which one I have, but don't know what the "T/I" designates.

how would I know if I have/had one? the factory distributor has been replaced with a Mallory dual point, so is there anyway to tell other than finding the engine code itself? If not, where might the engine code be hiding? Thanks to you guys here, I'm slowly but surely learning more about what I've got........

Hi Taz,
As Gregg said you're looking for the engine 3 letter suffix code It's stamped on the flat pad in front of the passenger's side head.This picture is of a small block engine but you'll see something similar. (the 2 groups will be reversed in position)
Good Luck!
Regards,
Alan

Look up ahead of the radiator support on drivers side, the amplifier was mounted on the inner fender panel. Here is a quick shot of the K-66 Transistor Ignition Amplifier on my 70 LT-1
