I want to rebuild a 454 for my chevelle that has the engine specs from the 1970 Chevelle 454 LS-6. Does anyone have or know where I can get specs on the cam, heads, pistons, etc.?

Heads are 291's
Pistons have a .270 dome
Cam is 242/242 @ .050 .520/.520 lift 114 LSA
called the "143" cam (last digits of the part number)
