Which plugs

[Joker Z28]

My motor is a 383 stroker using stock ported heads and a 12.3-5 compression.
I plan on going with a plate kit and probably spray up to 150 shot, I will start off small and see how things go.
I currently have the TR6s in there but I dont remember what they are gapped to.
Would the TR6s be safe to run spray with that much of a compression?

Also the car is DD and will be n/a most of the time and will probably honestly dont know how many times I will be spraying.

Thanks in advance.

I would run a BR7EF, or even an 8 if you decide to go with a higher shot (it is not called the BR7EF though, it has a different prefix). Only problem I can see is that it is a DD (the BR7EF's are said to foul out quicker while driving on them n/a). I have not confirmed this though.

I'm running the BR7EF's(non protruding ) and they do foul a bit when you are driving around the City, but a quick 1st, 2nd blast and there good to go.....

When you guys say the foul out quicker when dd, how often do they foul? (like about how many miles) also does n/a performance get effected?

Im running them and haven't had any foul yet. Im 95% NA and only spray every now and then. Installed about 5-6 mnths ago.

autolite 103 work good for spray

Back to my original question, does everyone agree with the BR7EF and if so where should I gap it at?

[Joker Z28]

TTT? plus gap?

I run autolite 104s for my FI application.

i used auto lite 103 gapped .35 when i was on a 150 shot. but there colder now.:) had no problems na.

BR7EF gapped at .035 to start.

If they are fouling out then the tune is garbage. We have never had that issue on several cars.

.035 it is
