To recap/add more info to the discussion:

1.) My car is a '62 Tudor. Originally it came with a 144 or a 170 six and a 3 on the tree.

2.) The car was swapped to a C4 sometime during it's life. From what I can tell a custom driveshaft was fabricated but the rest of the swap (crossmember, shifter, etc) was cobbled together. I had to run a vac. line for the trans. and fabricate a crossmember to get the trans. to work properly.

3.) The car still has 6 cyl. suspension, brakes (has brand new brake pads and wheel cylinders on it), and rear end.

I really only need the car to drive 2 miles to work on the 2 or 3 days a week when I have to work later than the bus runs. And to take a 100 mile interstate trip in it once every 3 weeks or so. It will probably never see much heavy traffic. And I don't intend to do any racing or other hard driving that will abuse the trans/rear end.

I'm still debating swapping in another six. I have been thinking about a 250 so I could use an AOD eventually and get the benefit of overdrive. But from what I've read to swap a 250 in you need Maverick 250 frame mounts and they have a different bolt pattern that the Falcon brackets so I'd have to drill new holes. I'm also worried that some 250-specific parts (timing gears, etc) might be hard to find. I am having a hrad enough time finding parts for the 200 six.

I just want something that if I need a water pump or a gasket, I can go into any parts store and get one right then. And I think I could probably do that with a 302 or a 5.0 motor.
