Gonna be on a bolt on LT1

Thanks, Joe.

 

So nobody knows?

 

.50

 

So, uh, you want him to gap his plugs 1/2 an inch?

....hope he's got a hell of an ignition system.

 

I think you'd be fine with .35-.40

 

The gap should be set at 0.050" That's the factory gap. That is most likely optimal with a bolt on LT1. It's what I have, and I gap to 0.050" with the TR55's. Car runs strong and smooth all the way to 6000 rpm, idles well, and get's great gas milage.

smart A$$ 0.050

 

Id say .040-.045 If i doenst really matter to you just run the .050 as advertised.

Brandon

 

The TR55s come pregapped at .050", which is factory gap and will suit your mods.

Mike

 

They are supposed to be gapped to 0.050", but I had to regap every plug. None of them were where they were supposed to be at for the gap.

yea, as a rule, i always doublecheck the gap, even though they come pre-gapped
