440 question

[coxie1996]

so im not going to be using the stock cone type oil pressure/temp switch (towrds the back of the engine)
i need to know the thread size so i can use my aftermarket gauge.

also i need new belts
i have the 3 groove crank pulley, with non siganaw power steering. and no ac.

would i need 2 belts?
1 from crank to p.s.
& 1 from crank, waterpump, & alternator?

thanks guys

The thread for the oil sender is 1/8 NPT(27) and you do need two belts.

Some, not all, 440 blocks have different threads in the rear for oil pressure. The one usually on the Driver's side is normal 1/8" pipe. The one facing the pass. side I have found some 1/8" and some 1/4" pipe.

No big deal as many of the aftermarket gauges come with adapters. Just FYI if someone is looking to run out of both ports and can't figure the difference.
