It was originally written '4-4-2' (with badging showing hyphens between the numerals), and remained hyphenated throughout Oldsmobile's use of the designation. The '4-4-2' name (pronounced 'Four-four-two') derives from the original car's four-barrel carburetor, four-speed manual transmission, and dual exhausts (Some maintain that the '2' indicated a limited-slip differential). The name was revived in the 1980s on the rear-wheel drive Cutlass Supreme and early 1990s as an option package for the new front-wheel drive Cutlass Calais. Introduced as an option package for US-sold F-85 and Cutlass models, it became a model in its own right from 1968 to 1971, spawned the Hurst/Olds in 1968, then reverted to an option through the mid-1970s.

Crower makes a set of springs that will swap right in in place of your stock springs but I can't remember the part number. Any of these cams may be pushing stock valvesprings. I don't know what gears you're running or whether you're prepared to change valvesprings, but I'd take a good, hard look at the following cams: Comp XE262 or Crower 60918 for more low end and midrange, or Comp XE268 for more midrange and top end at the expense of some bottom end. Not that I'm recommending that cam (like I said, it was an unexpected bonus in a core motor), just an example that a significantly larger than stock cam can be used even with low compression.

The idle's a bit lumpy but plenty of vacuum and I do have 3.73 gears, not sure what you're working with. I know installing headers and a good exhaust would also help a lot.

Even with stock exhaust manifolds this cam runs quite well in this low compression engine and there's power to 5000 RPM. I am currently running a Comp 270 magnum cam (because it was in a core motor I bought and in good condition) in my '73 4-speed 'bird, which is a stock '71 400 bottom end with 6X-4 heads that have been milled. Adding a couple of degrees of duration is not going to get the job done and the extra lift isn't going to amount to much either. Your engine is running out of breath at 3500 because your cam has too little duration. Adding the 1.65 rockers to your existing cam will only add a couple degrees of effective duration and about 10% lift at the valve. I *really* think a different cam would be a much more productive use of your hard earned money.
