A 15 mile trip to my doctor's office showed no overheating whatsoever but when I stopped and it boiled over.

Every last nut and bolt aftermarket, the gaskets, everything needed for the Cobra intake swap. I also have the Terminator manifolds with the steering shaft, the knuckle, and a little piece of D&D for relocating the shaft I would entertain offersjust
