I want to buy a GM crate engine 292 ci six .I want complete from valve cover to oil pan. I was given a part number #10121028(for new) and it does not have the integral manifold cast into the head. $Price is $1600. From a dealer in the midwest . Does the board suggest any other places I may obtain this motor? I would even take a rebuilt if it had a good warranty. Looking for someplace reliable that the list has dealt with before.Is the price about right?

Thanks
Ken
