I'm looking for some advice. I removed the 350 LT1 from my 70 1/2 Z28 and replaced it with a big block. I have no intention of getting rid of the 350 (it came with the car when I bought it off the showroom floor in 1970.) It has aluminum heads (the original cast iron heads are in a box.) and the engine is on a stand. Does anyone have any opinions on whaat I should do to protect it during long term storage? It will be in the garage and I live in the northeast where we have cold and snow in the winter time.
