Jim, the change from the 2.2T's crank to the crank used in the 2.4 liter engines lengthened the stroke and resulted in that displacement increase. The bore didn't change going from 2.2 to 2.4. If you went to the longer stroke, you'd end up with a hi-compression ratio 2.4T which would be an excellent engine in a street/DE car with as much or more HP than a 2.4E engine. The 2.5 short stroke Don N. mentioned is a nice racing engine.
If I remember correctly, the engine shroud changed in 72 or 73 to a two-piece unit that allows you to access the on-engine oil cooler without and engine drop.
