351W spark plugs?!?!?!?
I have a 351W in my truck and I am not sure what it is out of. All I know is that it is a 351W, carb'd. I have heard it is from an LTD, and also that it may of been a crate motor. Right now it has autolite 25's, They look short. There was half a set of longer thread style plugs in the glove box of the truck when we got it, Don't dare just put them in in case they are too long... Is there a way to tell what plugs it takes?
