Casting # info
I have a Chevy 396 block with the casting # 3935440 on the back of the block and a big T under the casting #, is this a tall deck block? If so what are it's advantages/disadvantages if any. I'm planning on using this engine in my chevelle, mostly street, some strip and possibly competing in a street car drag racing class. I just want to know if I have a good platform to start with or if I should look for another engine.
It also has Hi-Perf Pass and what looks to be a 12 stamped on the side of the block by the oil filter.
