I know you want to build something more classic ... But here's mine. It's built for 28s with muddies.
Rear centre is 16 & 1/4 ".
BB centre is 10 & 3/4" height.
Fork rake is 45mm
Angles are 73 HT and 74 ST
It's something like 59.5 effective ST (actual around 57cm C-C) x 56 TT, quite a strange shape, for a short reach and tall HT, which is 170mm.
The upright position om the tops is just wonderful, and means I'm comfy in the drops, even with my massive belly.
