This time it is for a Volkswagen, I will have other car mfg&＃039;s soon that I will need products made for as well. I will be able to send you a sample. From the time I send it to you, how long would it be until I receive a sample? As far as the quantity, it comes down to the price and KNOWING it is a GREAT PRODUCT. The heat treating has to be the best, the quality of the cro moly has to be the best the machining work on the crankshaft has to be the BEST. Is this something we can agree on? As far as the quantity it comes back to pricing. If it is good pricing, I may want 3-400 at a time. Can you supply a forged flywheel also? I will want the crankshaft in a few different sizes as well. Can you do casting as well? I need some cylinder heads as well in aluminum and they have to be of the SAME HIGH QUALITY.
