I was messing with a tech test on the summit raceing website awhile ago,a fun thing to do when you are bored.Anyhow,there was a question related to spark plug indexing.
Here is a link to explain it.
Would this help a T?
And if so,how could you set the electrode on a pipe thread plug? I doubt you could.Would probably need to use adaptors and 14 mm plugs.
Input? Ideas? Not worth the trouble?
On my list of 1000 things to consider, indexing spark plugs would be #5001.
On a high compression/high RPM engine you might gain a little but the T is far from that. The head, ports and runners are SLOW and designed for torque at a low rpm.
start with a couple dozen spark plugs.
because not all plug holes or spark plugs are cut identically you would then start trying all the plugs in all the holes until you find 4 that index..very worth while when the engine involved is supercharged at more 10 percent over, or compression ratio is 12:1 or higher.
