  • 1982 Firebird 2.8L Carb'd

    Hey,
    I got a 1982 Pontiac Firebird (BASE!!) with the 2.8L Carb'd. The thing is a tank and I was wondering if there was something I could do (cheaply) to push a few more ponies out. The car is for sale and I have a small asking price, and I do have someone interested, but they wondered about pushing more horse out of it.

    So is there anything I can do? And no .. lol .. not pull out the 2.8 and drop in a different engine.
    And by the way, she does have around 200,000 miles ..

    Thanks

    The best thing to do is put a weber carb on top. You might get like 10HP from the weber. A cam swap would do good too. But with that low compression, small valve, tiny journal 2.8L you are wasting your time.

    Unless the body and frame is mint it would be better to just buy a V8 Firebird. Even then the V8's in that day were so low on compression their HP numbers were not impressive either.

      Edelbrock used to make a 4v manifold for the 2.8, don't know if they still do, but you could probably find one on eBay. There used to be headers and after market exhaust for 2.8 f-bodies, too, but I don't think anybody makes them any more. Check the local yards, there should be tons of third gen f-bodies there.

        BTW slipping a small block in there is probably the easiest engine swap on the face of the planet!

          honestly, thats the easyest way, and a pretty cheap one to. you may be able to find a parts car for a couple hundred bucks, and swap the engine and trans in. or at the least, you would need the engine, trans, rad, and mounts. it should all bolt in and even all the wiring should hook right up.

          with the 2.8l, its base at 110hp, and thats brand new. im guessing itll be down a bunch from age, so lets say 100hp as it sits. you could throw in a cam (about 15hp) 1.6:1 roller rockers (close to 10hp), a 4v intake and carb (about 10hp). after those basic bolt ons will give you about 135hp, not bad for a few bolt ons. the problem is, you just spent close to $800 doing all that, and you have half the power of a small block, and you spent about what it would cost to swap it in.

          i wouldnt normaly discourage anyone from a 660, but in this case, if your looking for power, go with a v8.
