Mark,
You are absolutely right in that any SBC (283, 305, 307, 327, 350 even 400 - though I wouldn't recommend that one as the unique harmonic balancer, necessary for proper balancing, goes bye-bye), can be turned into a "Q" as long as the "Q" components are handy. Been there, done that. Other than the "Q" specific parts, the issues are really only, as we all know, the cam and the heads (nothing too hi-perf).
The real bear is getting the flange off the "front" of the crankshaft. You have to be very motivated!
