You could also call Scott Performance. Look them up in the phone book. They used to be in Santa Clara on El Camino Real. I bought my 70 240Z from them a while back. They have been working on these cars for many years now and they really know what they're doing. If your looking for someone to just give you advice on building your engine/tranny then I'm not sure they are your best bet. But if you let them build you one you will NOT be dissapointed. They are a bit pricey but you get what you pay for. Good luck.
