Oil temperature gauges - where to mount sender unit on small block ?

[dvw]

If you race, oil temp is a critical factor in detrermining ET. Personally my race car has one oil temp gauge. Two senders, one in the oil pan, one in the trans pan. A toggle switch allows either temp to monitered on one gauge by flipping the switch. if you are fighting oil pressure concerns a oil temp gauge is a necessity.
