This was 32° I believe. I was still messing with fueling, but this was a couple of wot passes on the highway next to my house.
E85 sure burns clean.
I don't think I took pictures of the 34 plug test. But the mark is just on the bend of the strap.

I forgot you’re running close to 12:1 compression on this thing. I’m surprised it wants that much timing, but the plug looks happy/safe to me! Have you verified the ethanol percentage of your e85?

Nah it's only 10.42:1. It had leaned out with the blower and melted things that aren't supposed to melt
Lol
Everytime.i pick up fuel I test it. So far so good. E85+ every time.

That plug looks extremely safe. You could probably add 2-3 degrees to your total. From some quick math;
30 less .5/psi after 2 on 7.1 psi.
(7.1-2) x .5 = 2.55
30-2.55=27.45 degrees.
I’d lock the timing at the track and play with it in 1 degree increments for best mph. Don’t worry about ET just run it out every time. Then build a new curve to get there for street driving.

9.2:1 on gasoline at 7psi, this pull was on 30 degrees. The timing mark was a touch to far around the bend to be completely safe in my opinion. I run this engine at 29 degrees at 10psi currently.

My down pipe comes out in a similar spot. Was worried about fumes but it’s been fine.

Are those old Cragar wheels?

Yes and no. These cragers are a couple years old 15x4.5 direct drill
Added a 2 step so I could leave on some boost. Definitely helped. Although I still need to add some more fuel for the back half. Starts to break up.

7,094ft DA - 7.14psi max -top of the track this run was about .81-.82 lambda just starting to break up. As the night got cooler the breakup got worse. Time to adjust some holes.

1.5 60', nice! What a big difference with the 2 step.
