Well not quite. A modern six has all the bellhousing, clutch and mount issues, but not the steering interference issue.
I like the 261 for this one too, though a 270 or 302 GMC would be options also, but keep in mind the front mount issue with a GMC and radiator clearance issues of either the GMC or any '55 or later Chevy motor.
