1915 Spark Plug Recommendation

one4house · Posted: Tue Jun 18, 2013 8:57 am Post subject: 1915 Spark Plug Recommendation

I have a 1915, Engle 120 cam, stock heads, 009 dizzy with point delete and 34 Pict 3 carb.

I just recently picked this car up. I want to get a fresh set of plugs in there. I was looking for recommendations for plugs and gap setting.

The 40 idf is decent. If you want to stick with the single, make sure the manifold is heated. Makes life MUCH easier in the tuning world. It will wake it up some, but if you want to really see what she can do...get two 40's and have some port work done. You say u have stock heads as well, are we talking stock rockers, springs, the whole smash?

Fair enough. Just make sure the intake is heated or it will never be quite right. Pop off a valve cover and do a visual on the rockers. If it has four clips on it and wavy washers and shims...thats stock. The 120 cam has a good bit of ramp to it and you will start breaking the wavy washers due to the side force created by a higher lift cam. Go solid rocker shafts (if not already done) and upgrade the valve springs. This should already be done seeing as it was built by an experienced builder. But an experienced builder (soley my opinion here) would not put that carb on that motor. just my .02. Not trying to be disrespectful.

Anytime! I have already hicupped through the single carb thing, spending cash, breaking stuff, crap mileage and poor performance. Always glad to share my f*ck ups so others can have a jump on the game..I'm still learning too and probably always will be..lol! The Samba is an AWESOME resource for parts and information. I'm totally addicted....lol

After a lot of searching, it looks like a NGK plug with .024 to .028 gap will be best. Does anyone know the specific NGK model number, so I ca n just take the guess-work out of it?

14 x 1/2"
14 x 3/4"

the spark plug threads in the head are what dictates the plug thread size. The most common is the 14 x 1/2". The stock NGK replacement for that is B5HS, but some guys run B6HS also.

With NGK

B or D is the thread size. B = 14mm. D = 12mm
The # is the heat range.
After the heat range, the first letter is the thread length. H = 1/2", E = 3/4".
the letter(s) after the heat range specify gap, or electrode types.

I don't know if I need to change the plugs. They not only looked new. They looked like they are burning great.

What does everyone else think?
