J-Grind Cam

[COPO]

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

Mark,

When installing this L88 cam....don`t forget to use a lot of WD40 on the install. We hear your favorite lubricant is WD40.

Motion did recommend a bigger cam to get maximum performance from the L/88 -- PHASEIII "S"model--.560/.580 lift--or PHASEIII "C" model--.585/.605 lift----(Competition Only "ROUGH" idle You should be running a 456 or an even better 488 with these cams---Charlie Mason was running a early L/88 CAM .540/.580 in the early days- -Then switched to a Motion J grind( which as someone mentioned was the letter signifying L/88 cam )--I would guess it was the same grind as KO-MOTION---PHASEIII "C" model of a J grind--Will check further----

O.K.--JR Replied back--"You can use the L/88 535 cam or the LS-7 cam I think it ends in 108"---Thanks--Joel

Hey Thanks everyone, Woow, great info. I'm suprised to hear there were so many diffen't grinds! I just love hearing about the good old days! I wish i could have expereanced the hey days but i'm only 34! Does anyone know who was the camshaft grinder motion used? Crane? General Kinetics? ETC... just wondering!
Thanks again everyone!
...One more question if i may, is there a motion car reunion anywhere?

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--

I looked through a few things I have.. I think the "J" grind might have been the .625-626 lift cam. I have an article on a wildass '68 Motion SS427 L88 Chevelle and it saids it had the "J" cam but didn't list any specs. The "C" grind was .610 lift and is in the Ko-Motion Vette. Thats all I found but I only looked quick.
