If you can't then you need to have a stern talk with your engine builder. An SBC in sprint car or Nascar tune will punch out 800-900 horsepower naturally aspirated. Depends on fuel mix, compression ratio, camshaft.Quote:

Very much so unless you’ve pulled several of the plug leads off. You think you can with a Rover 3.5? 😁Quote:

The small block chev is called small due to the block being smaller than the earlier V8's they had been producing. It is a very compact size and fits into smaller chassis than a big block can.
A big block is a much taller wider motor and also heavier, this extra block heigth allows longer strokes and the width allows bigger bores.
