What is the difference between a small-block and big-block engine?
The new LS7 engine by GM (in the Corvette Z06) is 427 cubic inches. Why is this a small block when the previous 427 was a big-block engine? What is the difference in the set up of the engines? I know that the cylinder bores are bigger in the new engine and the connecting rods are titanium, but what is the difference between a small-block and a big-block engine?
So what I am gathering from other websites is that classifying either a small-block or a big-block has nothing to do with displacement, but the distance between the middle of each bore. So is there a specific distance between the bores that classifies the engine as small-block or big-block? And note to the GM ASE ceritified person that answered: every website that I have looked at (rssportscars.com, wikipedia.com, superchevy.com, gmgoodwrench.com) all say that the LS7 is a small-block engine that uses the same architecture of a LS2 engine, just a larger bore and a longer stroke.
Essentially the only difference is the physical size of the block itself. The 427 refers to the capacity of the cylinders. In a small block 427 the cylinders will be closer together. This can cause overheating problems, which some people don’t care for. However, parts for a small block engine are less expensive and more readily available than those for a big block.
There are several overlaps between the small block and big block engines in Chevy’s history, for instance, the 396 big block, whereas the 400 is a small block.
Hpe that helps you some!
