The plugs will tell you the correct timing.

Unless the Chevy has a late model head they take 42 total most of the time. And big block stuff was about 40.

Every BBM took 39-40.

I'd be surprised if 34 is best power for you. The only way to know is to test.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
