Only amde in the 366 and 427 cid, no 396, 402, or 454. GM did make a few 500+ cid crate engines based on that block, also the DRCE pro stock block is based on it. The only real pro to using the tall deck on a street engine would be if you're going for big cubes (600+), otherwise, it's just extra weight. As HevyHaler stated, they use a different intake and distributor. This is due to the taller deck hight. Not much in the line of intakes being made, I have seen stock bbc intakes made to fit using spacers. If you're looking at one (I recall from another post you were), if the price is good (Cheap/free) it will work fine and be a good stout engine. Just don't expect to make a hi-power screamer out of it without doing some serious race type mods.
