331 Sparkplugs
Posted: Wed Mar 20, 2013 11:18 pm
Have a 54 (I think) 331 Industrial Hemi and need to know what plugs to run in it.
I bought the engine as a "short block" and it had AC-Delco R44XLS (3/4" reach) plugs in a box along with it.
1956 MOTORS Repair Manual shows that there are some different plugs that were used in the Chrysler products with V8 engines. Displacements were not stated in the manual.
Some being; Autolite 4GS-150, or 4GS-170
Would the R44XLS plugs be OK for "street" use? I can pick up new ones at NAPA
