AC DELCO spark plug question
Have 2 sets out in the garage from the mid 90's I have no idea what engine they are for, at the time I had a 65 and 66 roaster both S/B, a 68 coupe 427-400hp and my old reliable 77 with the 350ci engine, 1 box is R43 and the other is R44XLS, if anyone knows what engine these plugs will fit and if anyone needs them they are yours for the asking.

The R43's are cold (race) plugs for a pre-'70 small-block, and the R44XLS are for a pre-'70 big-block.

While we are on the plug topic:
Can you buy just the spark plug gaskets (14 mm). I tried at my FLAPS and all I got was a blank look from the kid at the counter.
Like to find some copper ones like they had in the old days.
