I first saw this picture in an old Petersen Publishing Chrysler Performance book about 14 years ago at an excellent car book store in Denver. Wished over the next 14 years that I'd bought the book. Finally found another copy. The photo shows a mix of stuff Offenhauser supplies and stuff the end user needs to modify or fabricate, though the text isn't too clear on that. The main thing to pay attention to here is the modified choke, item (C) in the left picture and also (kinda) visible installed in the right photo. Note how the choke pushrod has been cut short and a new "3 sides of a rectangle" rod has been formed out of appropriate rod (gas welding rod would probably work great) and brazed or zap-welded to the stub of the original choke pushrod. This is clever and clean, and as long as you take care to make sure the new choke pushrods are the same length and the new rod is "square" with the original rod's stub, should make for easy choke synchronisation. I would start out with one of the electric choke kits rather than a factory-type choke thermostat, and the kit number I'd use would be a #1234.



If you look REALLY closely, you can see the word "SPECIAL" cast into the cylinder head in the right hand photo above, and also you can see the lack of a PCV hose, indicating this is an early aluminum-block 225 in a non-California car, probably a 1961 Lancer. I don't think much of the way-too-small air cleaners they picked for this installation, but I can't blame them much...the "small and tall" factory air cleaner was still two years in the future when this photo was taken!

I first saw those photos in a Petersen Book titled "Hot Rodding the Compacts" that was printed in 1964. It was a compilation of their Compact car hop up stories going back to 1960. I believe it was a '61 Lancer they did the Offy mod to but they didn't go into any details on how well it ran. Who'd of thought that you could still buy that manifold 43 years later?
