I have not done one, but know several who have and have discussed the builds at length. Because I've thought about what you're thinking about. I've since taken antibiotics and recovered from that sickness.
I might put Hurricane 1a and Shell Valley 1b. The Hurricane is more accurate IMHO.
There will be slight mods with both, you'll find them along the way. The radiator overflow won't fit there or the clutch linkage doesn't line up right or the throttle linkage needs reworkinig, etc.
The build time will all be relative to your experience and the tool resources at your disposal.
Good luck and let us know how it goes.
