Re: 72 TA : New Project
No specks on porcelain. Stock compression of 8.5 to 1. They are the stock heat range 2869 platinums. What would a colder heat range be with NGKs? No detonation, even with 91 octane. Initial timing at 12 before TDC. Total timing around 36 degrees if I recall correctly. Has a minor nosing over/power loss at around 5000 rpm.
