Thanks but I just went on the AC Delco site and looked up a 1980 Camaro w/ 305 and it says that the R45TS is the plug for the 305 that year, or if you want to get fancy with the platinum plugs, the 41-905. It also says to gap them to .045.
I am very lucky that I didn't grenade my engine with the 41-932s. They are too long and the pistons must have hit them because a couple of them had the gap slammed shut after only about a minute of running. I said to the guy "Remember when you said somebody f-d up my engine? Well the plugs you sold me could have f-d it up big time." They actually didn't want to take the plugs back because I had used them for all of 30 or 60 seconds and even though they were clean, the gaps were all messed up. I asked to speak to the owner and he said he couldn't take them back because they could mess up somebody's engine. I told him that they could have messed up *my* engine but according to his guy they were supposed to fit and they clearly don't, and I wasn't paying $50 for a set of plugs that don't fit. So, he gave me a refund and chewed out his counter guy about recommending a plug without knowing that it would really fit. Anyway, hopefully I can change my plugs in peace now. John Nasta
