@IQ52 how did the timing numbers differ between the two combinations? Do you recall? And we’re both run on the same fuel?

38 degrees on #1 with the iron heads and 37 degrees on #2 with the EZ. Everything ran on 91 octane from the Stinker Station.

Even when we combined the roller cam and the EZ heads for 658 HP we ran on 91 octane.
