real numbers matching X-code Z/28 value ??

[HS PROFESSOR]

I have a friend with a real 69 camaro Z/28 that might be for sale shortly.it has been stored indoors since the late 80's.cant remember if its a X-33 or X-77,but the kicker is......he has the original and i mean original 302.the motor was taken out in the mid 80's and replaced with a 350.i'm sure the trans and probably the rear are not original as this car saw some serious beatings.it was pretty quick back in the day.if i reacall it may be a D-80 car also.it has tach and gauges and a rosewood wheel.but these may have been added over the years,maybe not.the owner has been surfing E-bay and knows what these cars are worth,but my question to you is .....what is it worth??? i'll be selling it myself and from what i can remember the body is not that bad.its blue w/blue int.the motor was pulled and put in the corner.original intake,valvecovers and pullys.THE ORIGINAL HOLLEY IS ON A PICKUP TRUCK SOMEWHERE!!!!.no stamping required here.the motor is 100% legit. values ???? let me know.again the last time i saw it about 5 yrs ago and it wasnt that bad.easy resto for sure.

ps.....when the motor was removed it ran perfectly and had less than 30k orig miles!!!!
