I'm trying to help a friend figure out the stock engine specs on his 81.

The two pieces of information we are missing is the specs on the camshaft, and the specs on the heads.

If anyone could post the info or a link, it would be greatly appreciated :thumbs:

If you don't mind, I'd be interested in that info.

I've had a hard time myself finding specs on the L81 :lol:

Thanks for the help :cheers:

Here's some stuff from the GM restoration package. I believe this is the info you are looking for. If you can't read it, let me know and I will email you it in a bigger file.
