tell me why

Depends on what power level you trying to obtain? Prices start to equalize back out the higher you go. The one thing that stays exspensive for us is aftermarket blocks. But then again goes back to supply and demand.
Favorite saying friend of mine has is"depending on how fast you goes depends on your cubic dollars."
There is more of a disparity in price on small block stuff but then again goes back to supply and demand
