Thats not what i'm saying, if you have someone do it that knows what there doing, then by all means let them. But I would want to know that they know what there doing, I here too many people saying oh I can build that, putting together 350s in there back yard is alot different then putting one of these together. All the tolerances are so much tighter, there's absolutly no room for error. There not hard motors to put together but they have to be perfect or they won't last. Right now for instance i'm building my b17. I know how to put the crank in, how to torque the rods, and install the pistons, but I won't do it by myself. My boss is going to sit there and make sure everything goes perfectly, why do I trust him, because he's been working on porsches, ferraris, mercedes, you name it for the last 30 years, he used to work for Renntech Porshe, he knows how to build a motor, not saying you need all that but you know what i'm talking about. You have to get someone that really knows what there doing to build a good motor.
