Autolite ?

Re: Autolite ?
Most people seem to run NGK TR55 in "stockish" LT1's. The iridium plugs seem to provide good results, and very long plug life. What advantage does your dad feel the Autolite plugs offer? Nothing wrong with them.

Re: Autolite ?
My car didn't seem to like the champions when I had them years ago when my engine was close to stock. Switched to TR55's and have used them ever since TR6's now I guess, but Im far from stock.
If it runs good and you still have the stock manifolds (harder to change plugs) then I would probably leave them in.

Re: Autolite ?
That will determine the recommended gap.
Nothing wrong with Autolite, I use them with the NA and small shot tune. And a very cold Champion racing plug with the 300-shot. The plugs and gaps were recommended by the guys that built and dyno tuned the engine, using those specific plugs. But with a "stock"/bolt-on/N2O engine, I ran NGK TR6's.

Re: Autolite ?
With headers I get 1, 3, 7, 6, and 8 from the bottom, the rest from the top.
anyway, with the NGK's they came pre-gapped at .044" and I always had good luck doing that.
