Yeah the TR55's are good for a 3.4" pulley and they aren't Iridiam. Supercharged guys want to avoid the Iridiam and the Platinum plugs.

 

Yah, actually Dan, the hardest question about spark plugs is what to gap my TR6's to... I have heard .52 for 3.4 pulleys, but I have also heard .49 is great for anyone at a 3.3 and below...So I'm still reading up on where I wanna be on gapping my plugs..

Also, thanks for the clip! I decided not to bleed the two clips together, but you can check them both out at the site, and let me know if you would like any changes!!

For a 3.4 pulley you want to be between .050 and 0.055

 

And you did your with just a standard gapping tool?

 

tr55's are just the stock plug, dont you need to go to a tr65?? i have tr65ix (which are iridiums, but if i shouldn't run iridiums i will return those)

 

Yeah, I have a professional feeler gage from Craftsman that I use.

 

As far as I know the TR55's are 1 range colder. I don't know much on these as I personally go with the Autolites.

I actually copied a write up that explained this last week so you would have missed it.

Here is the link to it: http://www.oqcgp.net/phpbb3/viewtopi...44&t=37942

 

Great article... For only 12 bucks, I think I may just end up getting both the AutoLites, AND the NGK's, and running my Aeroforce scanner to see which one REALLY DOES reduce more knock retard

Thats the beauty of buying those scanners... Now I only have to wait a month to install them

Thanks for the advice and references guys! I think I'm gonna buy these, but will hold on to the stock just incase

I thought the NGK TR55 were iridium, but I remember I have the TR 55ix which are.

Isn'tthe 10.4 MM wire over kill ? Like a race only thing ? I like them though.
I've have been looking into these also. http://www.crateenginedepot.com/stor...Sets-C127.aspx
And they are 8mm thats pretty good, no?

 

Truely it is overkill but you simply don't have to worry about wire failure or spark failure due to the wire anymore.

I do the same thing with my house. - Home wiring is rated at 14 gage so when I rewired all this 1950's era wire I upgraded it to the thicker 12 gage. It was harder to run than the 14, but I don't have to EVER worry about the wire overheating because of amp draw. the 20 amp will easily blow before hand.
