Magnum Summer Sale
Back 40 years ago a 327 chevy cost $500 more in a new car than a 283 and I'm sure it cost no more to make one than the other.
In the late 90's, you could buy a all new 350 chevy complete engine for $1195 whereby a 4 cylinder Chevy 2.3 engine was over $2000. I suppose that had to do with supply and demand?
Anyway, are you not willing to pay more for more power in a model engine? They are just playing the salesman's game. Charge what the market will stand?
