help on some spark plugs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was putting new spark plugs in my truck yesterday and noticed that I was putting in different ones than I took out. I took out AC Delco t44 and put in some AC Delco t43rs or 43 something I forget exactly I am at school right now. Could some tell were to find or what is the proper plug for my engine.

I have a GM crate 350 engine number 10067353.

come on doesn't somebody have this engine. The problem is that the newer spark pugs go into the cylinder about a 1/8 farther than the old ones. Just wanted to make sure they were the right ones.

I think the problem is with your description more the the knowledge here. Also most of us have to work, and you need to wait until more peopl get home from work. As for the plug problem, you need to be more specific than 44 something. For example, I would reccomend R43 somethinoranothers to a plug as hot as r45 or 45r somethings. I run 44's in my 350 and it runs fine. Those missing, or unsure letters tell what kind of plug it is. Also, since I am not a mind reader, tell me if you have tapered seats on the heads, or flat seats. Some of the crate motors even come with a combo seat so you can use either the gasketed, or the peanut plugs.
The more you give, the more you get. That goes for accuracy too
