is there any sites or does anyone happen to know what the original engine specs (1970)ie; cam, valves etc. were. I am in the process of getting ready to build a factory engine and I want all original specs, like she was a virgin coming off the line. thx steel

Everything you need is in the restoration package from GM. Tons of original specs, far too many to try to type out here for you. Best of all , it's FREE! The link below is the top link (always) in Chevelle Tech 2004:

That said, are you SURE you want to limit your performance to factory specs? They weren't as awesome as people seem to remember, and no one will tear your engine open to see if it's to spec.

thanks xtreme, i have that package. steel
