Oh yeah, the speed shop I'm going to has a lot of that stuff including various spacers ... but check my logic on this -


Once on the chassis dyno, do a couple of mild pulls with no air cleaner, dial in carb based on Ox sensor data.


Do a full pull, maybe two (again no air cleaner) and see where it all lands.
If the HP & Torque are basically where I want them, I would consider this the "goal" to strive for. If not, stop right there - time to consider a carb change or porting.


If a go, then try various buttoned up carb configs to get as close to the goal as possible.

... makes sense?
