They offer a new product and then make it so expensive that people won't buy it. They seem to want their R&D investment back all at once instead of being spread out over a few years. They have a good idea here, they should create a demand. Most engine builders want that 4" bore engine, well edelbrock offers a cylinder head specifically for the small bore small block chevy by them doing this they have create a demand for their product. I honestly believe that if a manufacturer would offer more cylinder heads, pistons for the sbm that people would take interest and in turn creating a demand. I don't remember the cost of the heads for the small bore chevy but it was affordable.
