Hi, I am going to do my next cam swap the right way, and degree it in. If it's off, I will order the timing set to fix it.

I have never done this before and I am going to do it with the heads on and motor in the car.

I already have the dial indicator from summit with a magnetic base.

I was going to buy this degree wheel and this piston stop. What I am unsure of is how to hold the wheel to the crank (special nut or something?) and how I secure the dial indicator to the aluminum head.

Also, when you measure for .050" lift, do you put the pointer on the pushrod with the rocker off? Or is that too unstable? Would putting it on the retainer with a checking spring be better? Where can I mount the wire for my marker?

 

Bump, really just need help figuring out what part to buy to hold the wheel on the crank. so I can turn the crank without disturbing it.

 

Summit Racing sells a LS specific Kit. Comes with everything you need. Its made by Comp.

Yeah I saw that, very expensive.

I want to piece it together. I think I already figured out how to hold my degree wheel on.

I use a very long bolt (probably 3-4x the length of a crank bolt) to install my crank pulleys. It still hsa the head on it, but I use it like a stud with a nut to pull my pulleys on.

I could just get two nuts, two washers, and sandwich the degree wheel on that. Then I can turn the motor with the bolt head and it won't stress the degree wheel.

Just need to figure out how to center it on the bolt, I believe the hole is larger than the bolt.

 

I know it's expensive, but having cut corners on other task, I have learned it's easier in the end with the proper tools. Your looking for precision here....I would buy the correct kit and re-sell it afterwards. Thats what I did. Only lost $30 or so bucks on it.

The post on my magnetic base has the same threads as the rocker bolts so I just unscrew it from my base and screw it a rocker hole to mount my indicator. This makes it very sturdy...hopefully you will be as lucky as me and it will work for you.

 

Sweet, I'll try that.

I was thinking of placing the dial indicator tip in the pushrod oil hole, would that work ok? Or do you put a checker spring on and use the retainer for the dial indicator?

 

I do it on the tip of the pushrod. You wont be able to use the post in the rocker hole without the rocker pedastal off and you cant put the rockers on without the pedastal. If you have an extra pedastal you can cut off all but the two rockers for the cylinder your measuring and then use the indicator post in the rocker hole. I did this to check ptv clearance. You have to be really careful setting up on the pushrod and make sure it will repeat to zero when you go back to the base circle of the cam. Just play around with it until you feel comfortable with your readings.

 

Thanks very much for the help man, I appreciate it greatly.

Eastern or western PA?

 

No problem. South central
