I hope I can get some help here,I am building a rod project,and plan on using a 348 out of a 61 truck.It was a manual,and I want to run a 350 auto.I have been told I need an adapter of some kind?What exactly am I going to have to search for?New small flywheel?adapter and bellhousing?Also need to get a car water pump,but the local checker,cant seem to find one.Please let me know who has gone through this stuff already.Thanks alot...Patrick
