I woke up too early today

And yesterday too for that matter, and the one led to the other. I had to get up early to catch the bus to the Lab Rat Keeper to get there by 1130 which required leaving the house by 0930. Which in turn required getting up about 0800, which is roughly 20 minutes after I finally got to sleep Tuesday night. So running on caffeine and adrenaline all day yesterday and going shopping and navigating the bus system I finally started to shut down about midnight instead of when the school bus picks up the kids across the street. And I didn’t sleep soundly so Mrs. the Poet accidentally woke me up early this AM instead of letting me sleep until I normally get up.

Also I was supposed to go pay my cell bill today, but I felt wonky all day and I was also still a little leg and foot sore from all the walking I did yesterday. So I’m going to go pay it tomorrow instead, but that means nobody will be able to contact me until I get it paid. I won’t be getting constant text spam and phone calls, what will I do? /s (official internet designation that the entirety of the previous sentence was snark). Actually I felt so wonky that I didn’t do a lot of things until Mrs. the Poet reminded me, like eating. I got breakfast on my own but after that I got a little at a loss, and would have missed eating completely without getting a reminder to consume mass quantities (70s media reference there, 25 culture points to the house of the reader who can name it).

Also I got another e-mail about that dyno test I linked to last week with the 494 torque at 4000 RPM and only 405 HP at only 4900 RPM. The people who made the manifold say that the 224°@0.050″ lift is about the lower limit on getting air through the manifold at higher RPM and that normal cams for the usual dual-plane manifolds will stop producing power about 4500 RPM, and that it takes a lot of duration to get through the acoustic ram tuning inherent in the manifold to get power above 5000 RPM. And that because of that acoustic tuning the low RPM torque wouldn’t drop off either, much, especially with a 383 making the acoustics ring. Another Bad Idea was using Tri-Y exhaust manifolds with this combination unless I’m making a car or truck to pull stumps out of the ground. Seriously, using this manifold requires a re-think of every component because of the strength of the acoustic tuning below peak torque and the way it interferes with airflow above the torque peak, including things that reinforce low end torque, like small diameter long-tube headers or Tri-y headers.

And I “rilly” need to wrap this up before my brain turns to oatmeal, yum, oatmeal…
