J-Grind Cam

[copojoe]

Hello Motion Buddy's! Just was wondering if anyone knows the cam spec's for the Motion J-grind cam? I haven't been on the site in awhile and i just read the post about the 67 chevelle 427 found and it talked about a J-grind cam! I'm a vintage chevy NUT! Love the 427's! I have a COPO 427 Clone! Sorry, can't afford the real deal!

Is this the same cam that the L88 had?? Mark

Don't know, that's what i'm trying to find out! I hear motion had there own special grind! Is this true? anyone have a ballpark guess what is was? Lift???? duration @.050????

I was just looking in my old Motion catalog and it say for the 427 ZLX(550hp) and 454 ZLX(575hp) used the L88 cam with a .580 lift, but the full competition motors 427 ZLX(600hp) and the 454 ZLX(625hp) used a .600 plus lift camshaft... That would be too radical for the street. The grind numbers on the .580 cam are 3879605/3879652. I hope this will help. Mark

I do know the "J Grind" was a .600 plus lift cam. I will dig through some material and see if I can find better specs.

Joe G where are you?

I got my info from my Motion catalog from 1975 and the only info was the full competition ZLX cam was a .600 plus lift. I hope you can find out what the grind number is so I can write it down in my notes just incase the L88 cam isn't enough for my 427 . Thanks, Mark

Hi COPO,
I haven't come up with any specific specs yet,but I haven't gone thru all my notes yet ,other than being a high lift long duration cam--In the meantime, I threw a lifeline to JR to see if he can recall the specs--
