My F100 is due for a tune up and I am wondering which is the popular choice for my 53 flathead? It is a stock motor. Thanks.
 
I'm running Champion H-10's in my 8ba and the local parts house had them individually for lawn mowers. So if you want to run H-10's and you can't get them at your local parts house try a lawn mower shop. H-10's are what my 57 Motors Manual calls for my 8ba.
 
Hi all I also run champions in my flathead but iam surprised on how many people advise me to toss the out and use NGK any one else been told this?

Since lawnmowers were brought up, I have had trouble with Champion plugs fouling in both cars and Harleys when other plugs like AC, NGK and Bosch all worked great.
 
I run Autolite 216's in all our Flatheads. I wouldn't put Champion plugs in anything except the garbage can...:eek: But, that's just me...;)
 
I have had nothig but problems from champion ,even when I worked for chrysler in the 70s it seems they really caused problems in the winter months especially,
I always try to use autolite in everything I can find them for and the ngks are my second choice, i tried nippondenso in my ford engines both early and late and had one instace where a ford 300 six just flat out quit left me stranded, never befor seen a set of plugs just give up and stall out an engine,it was across the street fro a parts store and all they had were 3 ngks in stock to fit my egine so I installed the three and managed to get it running enough to get it home and replaced the other 3 plugs and never had anymore problems.
Fordestes,
