I have a cam that I thought was a leinweber cam - its got a fixed gear but it looks like a leinweber cam -- has J54 on it I sent it to Mr. Jim and he profiled it for me

in .511 lift 34/64 278 duration 105 c/l
ex .486 60/27 267 duration 106.5 c/l

he says its a excellent mid to high rpm cam for 88" to 93"

its for engines 1970 to 77 1/2 - it will sit as I don't have any early cones -- its for sale

 

Prolly a Good RPM cam... not for me tho... I do Not prefer revs anymore... to expensive for me..back when I did it...
Off idle to mid is where I live now with my Shovel...

 

Where anybody with some sense should be with a shovel, too bad I ignored the sense part for so many years
