Default 1984 crossfire camshaft timing

I'm sure long time crossfire owners already know this. It was hard for me to find advertised cam duration. here's what I came up with.
269/271 202/206 @ .05 .403/.415 lift, LCA 114.5 , intake centerline 115, exhaust centerline 114, overlap 41. IVC 69.5
DCR is 6.9

Same cam as used in the 305 HO engines in firebird/camaro/ monte carlo's. I used a Comp 252 206 206 @ 050 430 lift 110 lsa in a 305 firebird. Nice cam and would play nice with a 350 in an xfire!
