View attachment 404433 I marked out what I'm gonna do with the base but the side of the lower trans is still in thought process. Really leaning towards squaring the rear up like the front. Raising it the amount I took off the base and come out from the base square. So let's here some comments here.
I got a comment.

Really nice farking porting going on there. Clean stuff.....

I didn't do much more than knock the nikasil overlap off. And then smoothed the intake tunnel up getting rid of all the ridges. It's sitting at exactly 80° right now.

Do you still have that resonant chamber from inside of the muffler?
If so, could you measure the volume of it?
Would prefer in CCs if you have something like an oil ratio cup.
Looks like you could hold it like I rotated your pic and depending on how wide,
I guess you would put your thumb or a piece of cardboard or a port blocking plate etc...
at the blue arrow and fill with water.

then one more request, please sir.
Could you post photos of it from the directions of the 3 red arrows.
Maybe a scale/ruler laying alongside would be just awesome.

I already threw it away. However I will try and remember to do this when I do the second saw for you.

It's more about direction of the charge than area IMHO.

Which is why IMHO kickers on the intake side of the B ports will help scavenging.
