converting from BB 2 SB...questions

[twangismythang]

Ok so my 396 is out and will need a total rebuild, not wanting to spend a million dollars to do so I am going to find a 350 to replace it with for right now. I have researched and found that the TH 400 will bolt up to the small block and that I can use my distributer, alternator and starter.

My questions are what engine mount differances are there? And where would I need to look for SB mounts if I will need them? Also does the water pump inlet and outlet go the same way as the BB?

In my quest for a SB, is there any differance in the engine mount locations?
I know I will probably have to go with an electric fuel pump if I find a newer engine.

The plan is to find a newer engine and convert it to carb and run some headers.

If any of you guys have make this conversion please offer any information that may save some grief, Thanks.............
