Cam

[Bill Bailey]

I want to print some info I got out of the December 2001 issue of Car Craft.
"You might be surprised to learn that '59-'61 401's were fitted with one of the most radical factory cam grinds of the day. It featured 299/290 degrees of duration and 0.441/0.439 inches of lift at 0.050 on the intake/exhaust, ground on a 109-degree center line. This grind helped air flow through restrictive head design and small 1.875/1.5 intake/exhaust valves, but left the stogdier Buick owners asking their dealers why their luxury liners ran so rough." Does anyone out there have a part number for this cam.
Thanks and take care,
Bill Bailey :jd:

Bill, I don't think it was 299 and 290 at .050. That would be one VERY radical cam. Jim Burek

Jim,
Thanks for the reply. I just re checked the above mentioned article and I quoated exactly as written in the 2001 Car Craft Magazine written by Tony Nausieda. That is why I wanted to post the info, to see if this was true and if so what part number would it be? The article continues as follows.
"The LSA was toned down to 114 degrees for '62, but the" rump- rump"Buick idle (as quoated from Hot Rod's '65 GS road test) had already become famous-or,depending upon who you ask, infamous" I would go on farther, but this typing will take me all night. I would really love to know if this is straight scoop. What do you say Jim? Thanks again for all the help with my car and take care Jim.

Bill, well, as I said, there is no way the cam has 299 degrees at .050. I'm sure it was supposed to be advertised duration.
Buick seemed to be rather optimistic about their cams .
A cam with 290 and 299 degrees of duration ay .050 would not idle at under say 1500 to 1800 rpm, period.
