SB Intake Manifold

These cars are not new or even close anymore, before you order you might wish to check what year heads you have installed. You might even may want to install newer heads that have hardened seats for unleaded gas. On the 273 this would be 318 small valve heads, which are very common. I would rec. checking with a older and local machine shop and see if they have some already done and left instead. Pricing can be very good to help clear there shelves. On early 273's intake the 4 barrel manifold will command a decent price, while the later intakes are very common.
