Pontiac Freaks Take Note: There’s A Set Of Ram Air IV Heads, Exhaust Manifolds, and Intake For Sale On eBay

If you loves some Pontiac action, we have found a pile of parts for sale on eBay that’ll make you salivate a little bit. There’s a guy selling some of the best factory Pontiac horsepower making parts on eBay and it isn’t piecemeal, this is the right stuff to take your Poncho straight up to Ram Air IV levels of power if you make sure the compression and camshaft are right. These are also some of the most small volume HP parts that Pontiac offered as well so they are not selling for cheap. The asking price is $8,500 for the whole load of parts. Steep? Sure. Just go buy the other ready to run heads that are growing on trees out there and you can save some bucks…if you can find them.

The Ram Air IV engines were really healthy and along with the round port heads, lighter aluminum intake manifold, better flowing exhaust manifolds, the engine got increased valve lift due to the use of a different rocker arm ratio as well. The 400ci engine was factory rated (underrated) at 370hp and 445 lb/ft of torque. Having driven a GTO with this engine in it, we can tell you that those numbers are pretty laughable. It isn’t like the thing was going to run down a top fuel dragster but for a reasonably heavy car, it moved out with great alarm and would burn the tires for as long and as hard as you wanted them to.

Factory Ram Air IV cars bring stupid money at auction. Why? Over the span of a couple years, only about 1800 cars were produced at the factory with this particular combo. Available in GTOs, Firebirds, and Trans-Ams not many people sprung for the option. The allure of 455ci over 400 may have been one of the reasons but we’re guessing the price for the package was also a turnoff for guys looking to score as cheap a muscle car as they could. Discerning buyers were rewarded with a killer car that could hold its own with virtually anything else on the street at the time.
