pppssssshhhhhtttttttttttt
Well I have a set of BOTH in 3/8 laying at my feet right now. I am going to sell a set , and use a set on my 4.3 v6 syclone engine since it wont rev past 6000 rpms (going 7/16 NSA w. g.plates on my 327 and the lt1 afterall).
I read that the gmpp ones are 30% stiffer because the rocker stud slot length is reduced, and its obvious when you put it next to the crane golds.....the only thing is doesnt that make them HEAVIER?!
Also, the crane golds seem to have a bigger oil hole, and a little more clearance under the tip, like 1/16", but are they weak?
The golds can accept a 1.63" max spring diameter, and the gmpp only 1.45" with a max of .575 lift ... dont know the max lift on the golds but I bet it would be higher. I am going to about 6K redline and .520 lift with my cam (comp 415).
The gold I have are used and the gmpp ones I have are new.
Here are pics so you can see the stud slot length differences. THANKS FOR YOUR OPINONS AND POSTS :
