Help! Ford Racing 514 stroker

[snake65789]

I got a 514 stoker crate motor from ford racing and it has aluminum heads trying to figure out what spark plugs i need the holes aren't tapered so i assume i need plugs with washer? Any info is a help!

Why not ask Ford Racing-they built it?

try researching on the ffr forums, or try to get a hold of mike forte he is a a ford racing dealer you may find his cell phone number on the ffr site.

i was thinking if your engine has edelbrock heads go to there site and look up the instructions pdf they will tell you wich plug they reccomend.

www.FordRacingParts.com does not list a 514 stroker, but they do list two 521 strokers.

Both engines use M-6049-SCJB heads. These heads use a Motorcraft AGSP spark plug.

Pick the heat range that matchs your application, cross referance that to an Autolite (such as a 3926), and go to Autozone and get what you need.

Before the 521 they had the 514 a few years ago. That motor is a beast. I still regret selling the spf I had that had that 521 in it

We use a BKE-6 NGK plug in most of the street engine with 10.5 to 1 or less compression. This plug should work in the engine you have or cross over to another brand if you would like.
We do some of the 514 to 552 C.I. 460 engines with the Aluminum heads, hydraulic roller camshafts on premium pump gas that make 700 to 800HP. You can get real good power out of them for the buck, just a little heavy in front of a Cobra. A lot of the guys say it does not seem to affect their car much.

Good luck, Keith Craft

We use Motorcraft SP-406 or Autolite 3924's with the SCJ heads.

X2 to the 3924's
