It was designed for a truck that worked all the time because the 248 was only available in larger trucks. A 44 or even a 45 works a lot better for the way most classics are driven today. 44 and 45 appear on eBay all the time. These plugs were designed for GM engines and that's all I have been using in the 50 years I have been toying with GMC engines. | | |
