Actually, Olds did publish dyno charts in the 60s. I have a 66-69 dealer parts book that has them, for example. I also believe they were reproduced in some of the 442 books that are available. Of course, whether you believe these charts or not is a question. For example, I've always been skeptical that with all the modifications, the W-30 motors were shown to only produce 5-10 HP more than the base 442 engines and LESS HP and torque than the Toronado engines. I don't suppose this had ANYTHING to do with the 10 lb/horsepower GM corporate mandate...
