Re: l98 stock cam specs

nevermind, just found this on the front page:

GM Stock Cams
Model Number .05" Duration 1.5:1 Lift 1.6:1 Lift Lobe Sep. Notes
14093643 202/207 .404/.415 .431/.443 114.5 87 350,305man
10088155 179/194 .350/.384 .373/.410 109deg 87 305 auto
10066049 207/213 .415/.430 .443/.459 117deg 88-89 350,305
10111773 202/207 .413/.428 .441/.457 114.5 90-92 350,305

although i'm not quite sure how to read it. is it saying that for 88-89 cars with a 350 came with a cam with 207 duration and 415 lift at 1.5?
