Might want to recheck you math,  no way you can get 3.0L with a .040" over bore, I did a 89.5mm bore and it did not get to 3.0L

Try the one out of a 78 620 w/MSD.  Much like the "match box" but more reliable if you re-curve it!

Check your accelerator pump discharge nozzle to see if it squirts

106 Intake centerline.  I'm trying for 107, 110, 


I ordered an adjustable gear out of Japan this morning.  If I can pinpoint a couple settings that work on the dyno, I can drill stock gears to match what the adjustable gear is set to very easily, so I don't even have to use a bushing.  


I also plan on modifying a "fixed" timing chain tensioner, given how short our races are.  That would allow us to try cam timing changes on the course in a matter of minutes.  


Isn't the Nismo gear a modified stock gear?  Assumptions are a dangerous thing.  The big problem is that we don't know who is modifying them, and how many people/shops are doing it.  


All of this is required due to the radical cam I'm playing with.  The guys at Schneider Cams said it was the most extreme 4 cylinder cam design they've ever ground, which means it had to be ground off-center from a normal grind to provide enough meat for the lobes without running out of hardened material.  I'll have to break it in with light valve springs, then install something a little stiffer to be able to sustain the high rpms I need without valve float.  I'm pretty sure 225 over the nose isn't going to cut it.  

I don't know where you are getting the info on the gear changing the Cab lobe separation angle, the gear will change the torque/HP band.  The Nismo Gear is NOT a re-drilled stock unit, Google for the Nismo specs/  even the stock settings in holes, 1,2 & 3
