WHOA!!!! do not spend that amount of money. You can go on Ebay and find a complete unit with brackets and thermostat for $189.99. shipped free. I recently bought a "Ford Racing" Manifold from Toulsey Ford Parts Tousley Ford Parts Depot Their unit is less, but you have to buy intake manifold gasket, thermostat and bracket and works out to be same as Ebay unit. They have great prices and service. As far as installation, it is a bit
tedious, but not complicated. I am sure that once you get all the parts in it can be done in under 6 hours. DIY
