|1971BB427||Many aftermarket aluminum heads have 3/8" pipe thread holes for temp sensors. Mine do. The stock factory heads are 1/2" pipe thread.|

Should be 1/2" NPT, 3/8 NPT hole wont fit typical after market gage bulb and fitting
1/8 hole wont fit a 1/4 inch anything

Nope---1/2" pipe thread
a 1/8" pipe thread is larger than a 1/4"

|bracketeer||there the same size as a heater hose nipple. i thought they were 3/4 inch|
|05-16-2012 07:58 PM|
1/2 in or
3/8 if a small hole
a 3/4 pipe thread hole would be about an inch or more in diam.
