First question is can I drop the oil pan without pulling the engine and second question is will a 350 adapt to my 4 speed transmission or would I have to swap out both?

You'll also find that the front motor mounts for the 230/250 sixes and the V8's are in the same position. A 292 six has the passenger's side mount offset about 3" forward. If you loosen the motor mounts and jack the engine up high enough, the oil pan should come off, but getting it back on without creating a leak can be a challenge. What's the reason for pulling the pan?

It's very difficult to pinpoint the source of a leak if the whole engine compartment looks like it was in a gusher in a Texas oilfield. There used to be a bright red dye we could put in the crankcase to help locate the source of a leak- - - -don't know if that stuff would still be on the market since the tree huggers started getting a case of the vapors about common sense diagnostic procedures!
