The " Blower" cam that I have was made by Engle from a new core. We added some exhaust duration to help with being forced to run manifolds and full exhaust. It works pretty well at the strip, (best of 105.6 MPH) but is reasonable on the street with 3.25's. A little rumbely at idle of 700 RPM.

I have what is suppose to be a repop of the blower cam that Mummert produced a long time ago.  While it certainly has an impact on low end torque, I can still do truck stuff with it.  I wouldn't want to all the time, but it gets the job done, when needed.  If you used it strictly as a truck, then the cam would be terrible but for a fun street cruiser or street/strip truck that does occasional truck stuff, it is fine.  I've had this cam in 2 engines, one a very mild 292, and the current stroker and in both cases, I have the same opinion.

in the mid 80s  i was doing a 312 for a young man,sent the cam to the camgrinder ,he called and wantd to trade cores as he had a customer with supercharged bird and needed the core ,which  he claimed had special markings. i traded him as he advised that the blower grind would not work well in the na 312 going into a 56 pickup.(it was barrey at shadbolt cams who i did and still do deal with) i would be inclined to take his word. he also stated they did research for ford as in canada ford had cronic cam failures in 1956,something to do with the parkerizing process. hope some of the ford retirees will confirm or deny this. i am very interested in failure analysis as took training from cat.  not trying to say any  one is right or wrong,just hungrey  for acurate info. cliff

myn has a picture of a 406 on the cover late 62,when did  the 1st 406s com,they  became 427s mid 63

Meteor, 
           The standard F code motors used the same cam as the D or 245 hp engine. In other words they all had the same cam in 1957.
       There was an optional camshaft available in both the E code and F code engines. Standard cam ratings were 270 and 300 hp.
The optional cam, which has been called the F code cam shaft was rated at 285 and 340 hp respectfully. I am not sure the factory ever actually used those ratings, I believe that those were AAA and NHRA ratings for class purposes only. Then everyone began to use those numbers to identify engines with the optional parts.
