I have a Solid lifter General kinetics cam in my 377 sbc drag car. I ABSOLUTELY love this cam, Unfortunately the #6 cylinder cracked and I now have to replace the block. I am worried about reusing the old cam/lifters in a new block as I have never had any luck with break in after a block change. I purchased this cam from a circle track racer many years ago new but no box and no card. I know roughly what the lift and duration #'s are but now I would really like to have another twin to it ground for me. This camshaft flat out worked and I want another! The #'s are as follows 372L 300M 108C. Any help would be greatly appreciated. Thanks

From another forum..
"General Kinetics cams= C.=Chevrolet
M= Mechanical
H= Hydraulic
1= Small block
2= Big block
300= Advertised Intake duration with 1.5 rocker
a-z letter suffix= modification of original design. More exh dur., changed centerline, changed exh pattern, etc. EXCEPT the "R" series of "Redline" cams. These were the "White box" mass produced street cams that you can still buy under a dozen different brand names."

Maybe UDHarold will stop by this thread and help with some more ID info..

I have a GK book and I will look it up soon I find the book,

possibly 372 cam lift which would be .558 lift with a 1.5 rocker. 300M is likely the advertised duration and the M is mechanical. 108 should be lobe sepration. Just a guess.

the specks for the gk cam is adv. duration 300*
@t.o50-264
lobe- .372
lobe seperation-108
lift @1.5-558
hope this is of help thanks Ed

I think Lunati bought GK years ago, i may be wrong but i remember something about it. Give them a call

Thanks a bunch guys. I am hoping Harold can provide me with some critical specs that I will need to grind a copy of this cam. Ie ramp design major duration etc. Thanks for the direction.

These are straight off G/K's tech sheets I got from Camshaft Merchandisers, Inc., Detroit, MI back in '92.

lunati owned gk it was run as an indipendent co in miss when holly bought lunati it got the gk operation . it continued on for a while but all sales was handled in boling green
office as was the lunati brand needless to say they screwed up soon they did away with the gk brand and almost did lunati in and as Ud Harold said " he got a lesson in the corpret world'. and he was fired. the company was finaly sold and Harold is now doing design work for them and coustom cam co in va.the 300m cam is a mechanical cam and
I believe it sets on .024-.036.

Right,

I want UDHarold to write a book like Harvey Crane has on his wed site!

Just a thought but I would assume that someone like " Wolfplace" or "CNC Blocks ", among others, can "profile" your cam and tell you exactly, what's what.
