Hey, would you happen to know when the intake begins to open BTDC, or closes ABDC?
No sorry, it doesn't even list it in the shop manual either. To give you a idea, the crane cams I have are= Int. opens -4 degrees atdc/ closes 36 degrees bbdc. Exh= opens 32 degrees bbdc & closes -8 degrees btdc. 4 degrees overlap= intake closes & exhaust opens. This is cranes #224-0010. I do like the next one= 224-0012. Int.= 226 @ .050/exh. 216 @ .050 w/ .410/.385 of lift. Int opens at 3 degrees atdc/ closes at 43 degrees bbdc. exh. opens at 38 degrees bbdc & closes at -2 degrees btdc. The cranes are on a 110 LS vs crowers which are on a 114 LS angle. All the 23 motors should of had cams similar to the cranes spec's to begin w/.

Would like it for an approximate comparison to performance cams.

Thanks!
Duration @ .050 int. 203/ exh. 190 LS is 110 degrees gross lift= int. .359/ exh. .318 Pretty wimpy. A little more duration & lift gets you a lot. The stock head out flows the oem cams.
