Well, cool dad 
Maybe you can change the mains without throwing off the carb synch.
Hope it works noticeably better for you!

Parallel thinking? Is that the term?

We struggle with fuel economy with the car. The 5 gallon fuel cell is barely enough to finish a half hour session. I think we calculated like 7mpg. So larger jets could be a problem there.

On the dyno, we removed the red sox and gained a hp or so.  Then we removed the filters completely and added another 1.

So I fitted the short rounded intakes 9 Too short to call them bell mouths and added another 2 HP at the top end.

I don't think I scanned the dyno chart, so I will have to look for them to see the effect on AFR of the changes.
