I'm positive that it would have to be. A 90 isn't much different than an 88 or 89. Now the engines that came out of cars had this plug. The 350 that's in my truck now came out of a '90 Cadillac. It's the exact same block as the engine I pulled three years ago with the exception that the one I have now is roller-cammed.
