I got the 289 back from the machine shop. It already has the Weiand Stealth intake manifold and aluminum heads and oil pan already installed. I have to put on the rest. I am thinking I should install the water pump, HiPo exhaust manifolds, starter, transmission, carburator before I put engine back in car. I am not sure if it would be easier to put accesories like atlernator, power steering pump and fan on before I put back in car, or after. Any input on doing this would be appreciated.
