Sorry to ask such a routene question. The search feature of is coming back with internal server errors for the last day or so, and I am in need of some information. I would like to know the stock 86/87 cam specs to compare to my new 210/205. I would like to know the stock running duration, lobe lift, valve lift. Also, what was the overlap?

According to an ATR catalog: avertised duration is 258 intake (I) and 262 Exhaust (E), duration @ 0.050 is 192 (I) and 196 (E), lift with 1.55 rockers is 0.384 (I) and 0.408 (E), lobe separation is 107 and overlap is 38
