also, what radiator did you use?

Best case (a 300D with a 3.07 diff) is 83% of 300D speed in a 240D with its 3.69 gearing. Worst case (2.88 diff) is 78%. So you're doing good to reach 90 MPH and no wonder the temp is rising, the engine is probably running flat out. You need to find a 300D differential, preferably one from a 1985, which has the higher (2.88) ratio.
