LV-T15 and LV-T303 File Locations

[septemberWaves]

I am attempting to make some custom tech tree configs with CTT. For this, I need the internal name of each part that I wish to relocate in the tech tree, which so far I have been retrieving from each individual part's config file. However, for some reason I am entirely unable to find the config files for the LV-T15 or LV-T303 engines. I know that these are added by Making History; I have checked in the Making History parts folder as well as in the stock parts folder (just in case), but the config files for these engines do not appear to be anywhere obvious. Where are the files for these engines located? Or, alternatively, what are the names used in the game code for the engines?

@septemberWaves The Valiant and Pug are not stock engines. They are part of Missing History or some other mod you may have that adds in Porkjet's engine revamps.

Oh, they are not added by Making History? That will be my mistake.
