I have a 1969 GTO Ram Air IV without the original engine. It currently has a 1970 455 HO. I have looked for a few years for a ram iv engine, no luck. So what should I do? Should I get a 400 block, then look for ram IV parts; heads, intake, card, exhaust etc?

They're going to be very hard to find, and expensive... I have a pair of #722 (69 Ram Air IV) heads that I was running on my car, then one of the exhaust ports developed a crack. I tried to have it fixed, but it didn't hold, so now I'm running ported Edebrocks and making more power than I ever did with the #722's. When I bought those heads about 15 or so years ago I paid as much for them as I did for the car.

Take a hard look at things and ask yourself why you really want a Ram Air IV. Believe me, I understand the cool factor - big time. However, since the original engine is long gone it will never be 'numbers matching', so that's going to hurt resale value - if that's what you care about. If what you want is power, you can start with almost any 400 and with the right combination of parts build a Pontiac that will eat a Ram Air IV alive. I'm pretty sure mine will :D

It really all comes down to what's important to you - I +DO+ understand wanting a real Ram Air IV. You'll be the envy of everyone who lays eyes on it (including the nefarious types you'd prefer not to know about it).

Thanks for your advice Bear. I have the car since I was 18, I'm now 49. I really would like to make it original, or in the case of the engine as original as possible. So I'm looking for help on how to best do that. I don't mind spending a lot of money for engine parts.

Put a wanted ad in on the performance years forums. You can probably get what you're after, if you have the $$$ and are patient. While way cool, the Ram Air IV engine is not nearly as street-friendly as the 455 you're running now. They are high strung and happiest on the strip with a steep rear gear.
