Found my dads original 1971 duster!
There also should be no play in the clutch unit. Don't know how I forgot about that since I've been bit for ignoring that one.
----------------
Getting ready for driving and tuning, lets look at the dyno sheet.
To me this looks like a pull for break in and check for problems.
A tuning effort would have BSCF and fuel, and possibly a wideband (AFR estimate based on oxygen left in the exhaust) and some other stuff.
I will guess they ran the timing at 35* that they measured at 3000 rpm. Since we don't know the engine temperature for the pull, best to start with something more like 32* at 3000 rpm.
I don't see much more to be mined out of it right now.
It would be nice to know what cam and pistons went in there. Got anything on those, and cylinder volume or compression?
if you don't, its OK. But if you do, it will be helpful.
