Looks like you got some hogging to do. That AM intake looks a bit narrower too, or is it just the angle of the pic?
Here are pics of the jugs and misc parts. Measuring the intake opening from the base, it is 21/32 on the D jug, and 13/16 on the Big Bore. That is over 1/8" difference. A lot easier to see in real life than the pics show.
Perhaps that is an extra trigger pin, but it looks small for that.
Looks like a brake handle bushing for the recoil side. Hard to tellThat makes sense! Any idea on that other thing???
+1You could trim the intake side skirt of the piston instead of trying to grind the intake port.
Similiar affect
If you raised ex to 102, left trans alone and took intake to 75 would it gain?So, I re checked my timing #s on the new case, just to make sure the case is the same and I did not muff anything up.
Ex and Tr stayed exactly the same at 103.5 and 122, respectively, and the new intake # is 72.5.
That may not be a great intake #, but it is a heck of a lot better than 64. We will see how it runs, and maybe I'll do the next one a bit more aggressively (on the intake) to see if it is worth going back into this one.
If my 046 D jug and Hemi 460 jug are 74 + 75 w/o base gasket, they must have been close to that with a base gasket.
