[Healeys] Motor Install

[linwood rose]

Well, in my 5 year restoration project I have certainly asked many  
questions, but it strikes me that in the last few weeks I have asked  
more questions than ever about very disparate subjects. Here is my  
enquiry for the night:

If one installs the motor without the gearbox, and tightens down the  
bolts on the motor mounts, do they sufficiently support the weight of  
the motor so that the car can be rolled around in the garage/ 
workshop? Or, must one have a jack or other form of support under the  
rear of the motor at all times to prevent potential twisting of the  
motor mounts?

Also, I have my 2 original dowel bolts that go through the bell  
housing into the backplate at 11:00 and 5:00 o'clock. Is the smooth  
shank part of the bolt a tight fit into the backplate - as in tapping  
with a light hammer required, or do they travel through without much  
friction?

Thanks as always for assistance. Obviously, I am getting ready to  
install the completely rebuilt motor which is a great feeling!!
