If he's real familiar with our cars and parts I'd estimate a day and certainly in a weekend. The front fascia needs to come off for the heat exchanger which makes the I/C pump easy too. The draining of the cooling system is messy. The pulley saver kit caused me a headache because I was clumsy that day. Fuel pump is easy as pie but I managed to soak my arm in gas. The intake manifolds are a snap if you've done them before. Please use stock gaskets with copper spray. I finally listened to others and ended my nightmare of leaky gaskets.
