Cleveland blocks 2

The pillow block was used in XD and XE Falcon/Fairmonts and came about due a perceived need to increase the cooling capacity and capability of the Cleveland block. It was felt that as more and more cars were fitted with accesories, and specifically air-conditioning, it would be better to make some modifications to the block. These took the form of adding bulges, or pillows, to the casts to allow extra water jacket capacity.





There again seems to be some doubt about the provance of the ‘pillow’ block. Was it fitted to XD and XE’s ? Was it restricted to air-con cars only ? Was it just used on F100 trucks ?
