is my crank a 4 speed crank??

Measure the length of the input shaft from the face of the trans.
Mount the bell housing to the block and measure from the depth (hole) of the crank to the face of the bell. That'll tell you if the crank is deep enough.

If the shaft length is ok, go w/the roller bearing.

Yup, use the Magnum pilot BEARING and measure the transmission input shaft length. If you don't have enough depth in the crank pilot hole, you can lop off a little of the input shaft. I wouldn't take off any more than a 1/2" or so. More than that and I'd drill the hole deeper. What year is the crank? If it's a cast crank, you're going to have a balance problem unless you do some serious internal rebalancing.
