I agree Z10Mike,
I was considering modifying the stock Muncie shifter handle to work on the Hurst shifter so it looks original.

Copy that KurtS, I already corrected that. It should also be a Muncie shifter, not a Hurst.

You were right X33RS, I learned a lesson from this.

Thanks everyone for the help. I readjusted the valves over the weekend and it now runs and sounds great. For some reason number 1 and number 4 valves were a little loose. I originally used the EOIC method when the engine was on the engine stand. This time I used the 90 degree method which I think is the best method to make sure the cam is on its base circle.
I chased this car for about 30 years which my ex father in law bought new at Harry Mann Chevrolet in Los Angeles (68 Z28 RS). Its been sitting for about 25 years and has 67000 original miles, original paint and interior, all #s matching and extremely well documented. He told me he used to adjust the valves with the engine running. He would use cardboard to deflect the oil to keep from making a mess.

Good idea ko-lek-tor,
I will check to see which valves has the most lash. I think there are 2 that are just a little noisy.

Thanks X33RS,
I think I will stick at the .030 like you all are suggesting.

Speed Pro says .030 just like the original cam. If you read the John Hinckley and Duke Williams method at the link below they state that the stock rocker arms which GM advertised as a 1.5 ratio are actually a 1.37 ratio and that's why they recommend .026 to .027. So I am wondering if the Comp Cam 1.5 ratio rockers changes this.

Maintenance / 302 Valve adjustment
« on: October 21, 2018, 07:33:47 PM »
Hello everyone,
I would like to ask about adjusting the valve lash on my 68 302. I have rebuilt the engine and now have it back in the car and running. While the engine was still on the engine stand I adjusted the valves using the John Hinckley and Duke Williams method as found on this website. (start on TDC and turn the engine 90 degrees 7 times adjusting 2 valves at each 90 degree position at .027). Now that the engine is running and somewhat broke in (there are a couple valves that are a little noisy) I am going to adjust the valves again. The cam I installed is the Federal Mogul Speed Pro 30/30 grind part # 53059 12002 and the rocker arms I used are the Comp Cam 1.5 ratio roller tip stamped steel rockers.
Here is my question......Is the Speed Pro 30/30 cam Identical to the original cam where this adjustment method would still work, and are the Comp Cam rockers different in some way that this adjustment method would still work? I think the method is fine but would it change the .027 clearance?
Thanks in advance to everyone who replies.
