Who should I buy a 727 or 904 from?

There are crate engines in the 20K and up range. I can certainly see a transmission in the 4K range. As to whether anybody is raping or ripping people off, that's soomething altogether different. I don't know about any of that....I've always built my own transmissions. But if any of it's true, whomever is guilty is a crook, plain and simple. I don't give a **** who it is. That said..........
