I’m sure you’ll be fine with the LS engine as I’ve seen the Entropy setup used multiple times with that combo. I needed about a 1/2” to make it work. Entropy suggested I lose the shroud and zip tie the fans directly to the fins which would net me the space needed but I’m not down with that. I didn’t spend all that money on their piece just to take off the part that stands to provide a benefit. I took the fans off the shroud and installed the radiator and I’ve got 2 1/4” of space for fans which would leave me enough room to service the serpentine belt if needed. There’s a few things about the setup I don’t like but we’ll see what I can do with it. If I can’t get it to do what I want, it’ll be in the classifieds and I’ll buy a PRC radiator.
