Moroso Drag Spring Users

[classic boost]

how much longer was the moroso springs compared to the stock springs?
i bought a set off ebay and although i haven't removed the stock ones yet, the 'morosos' don't look much different. spring diameter is almost identical also.

Do they make a small block spring? If it is for a big block they may not be much different from a stock 289 equipped car.
