That’s normally a good area. Give or take….
It’s worth playing around with it to try & find a little something. Mileage settings and power settings for the track can only be combined so much.
It is possible to strike a good balance.
A local guy I know asked me how to get more power out of his 318 Duster. (Sporting a ‘78-318) I asked what he did for timing. It was @ stock settings. I’ll just fast forward to the end area where I cautioned him on using a race advance curve. He went there anyway. The engine started to knock. The move was made from 87 to 89 & the knock went away. So I asked him a few questions.
Does it feel faster, stronger? A resounding YES!
What did it do for mileage? I’m waiting on an answer….
I do not know how total with the vacuum hooked up.
