now i have afr aluminum heads and they said to run an autolite 3932 not sure if thats a colder plug was curious what you guys think 468 bbc tunnel ram with with 750s 10/1 compression msd 6 running 93 octance timing at 32 degrees
IMO...you might find autolite has a bit bigger selection of ranges. If you can find a "real" parts store w/a paper cataloge...check the buyers guide/heat range chart in the back. Also...don't forget, sometime you can use 5/8" hex plugs in place of 13/16"...space permitting. We did a lot of this in my dirt-track days.
Correct me if I m wrong an Autolite 25 a short reach hot plug and a 3932 is a long reach racing plug very cold, make sure you are installing the right plugs
