This is what I was referring to.

Its a digital manometer, not a vacuum source. You can run any vacuum/pressure source(s) you want on it. There are depression controllers available as well. I get the feeling more credence is given to the people on youtube writing numbers on a piece of a paper like the good ole days of analog manomet...

First time anyone has called it flowquick data and not flowbench data. Didn't know the box converting depression into digital data was the defining factor.

what brand of tool should I use for this?

We have less length of intake port in our heads than most engines, and more exhaust port. You can't compare flow/cc between those heads. You could for any aluminum head pushrod GM 60V6 though.

Compare the outside runners with the middle runners of the lower intake.

Let me know when you bolt the lower to the head and shine your light through the manifold while blowing smoke through the injector port.

Yes, streamline that intake guide. big gains.

Check out frameworks. Repairable, upgradable. I would use a newer AMD chip over Intel, as intel has had problems with their 13th and 14th gen stuff. The new new is no hyperthreading and I know you aren't gaming on it, but it was a decrease in performance compared to their last gen. Bleh indeed. http...

It calls for SBC lifters? Spacing won't be right for the linkage. I have yet to find anything with the correct geometry. Clearance between rockers, valve cover, and lower intake is also going to be quite the issue. Even the LX9 is difficult for rockers because of the raised intake port. You will als...

Polymaker PA-CF is supposed to be annealed at 80C for 6 hours. I do it with a big food dehydrator. https://www.plasticsintl.com/media/b1waaehe/polycarbonate-annealing.pdf That is what I found for polycarbonate, and it has a max ramp and and down rate for temperature control. If its not that strict,...

Its a smaller pump than the DOHC. From memory, I think the DOHC was 40% more flow than the stock pumps in a 3.1 Gen 2 motor. The HV is 20% more flow, and you gotta make sure its the 3/4 tube vs 5/8 on the older stuff. Either way, the DOHC pump is the biggest you can get for a 60V6. Maybe the LZ are ...
