Torque Specs on ZL1
Does anyone have the torque specs for a 69 ZL1, and are there any special things to do during assembly that are out of the ordinary from a regular block?

I did a quickie search of the archives and didn't find that thread, but thank you that is right on what I needed.

Re: Torque Specs on ZL1
One more question please, has anyone ever heard of warming the block up before torque? Either by hot water or space heater. Some one told me this, and wanted a second opinion on it. Seems to me room tempature would be best. Since heat should expand it, when it cooled back down you might have a less than accurate torque?

Re: Torque Specs on ZL1
I don't know much about ZL1s, but I have always liked to retorque head bolts and exhaust manifold bolts after running the engine for a while.
I have read somewhere that the bolts are all longer on the aluminum engines, and that why you can apply the same torque as on a iron engine without stripping the threads. But I'm not the expert. Fortunately, I happen to have recieved something nice in the mail today. So here is what the Motion Performance Chevy Performance guide had to say on this subject back in 1971. http://www.sonic.net/bbdon/free/zl105.jpg |
