I have in my possesion a pair of the green QFT 2 circuit blocks. I also own a pair of the red QFT 2 circuit 3 emulsion blocks. Soooooo.....I thought I'd pop out the mainwell plugs to see whats in there. Both blocks have identical mainwells which a #2 tapered reamer is too large.
The green block emulsions are .027, blank. .027, and blank. Anti-siphons are also .027. Mainwell exits are .160. I really thought that these blocks would be a little more special than just anodized green and a fourth emulsion.

I have seen this as well. The original blocks were the ones described above. They changed their design on the newer style. They are a little different than the red blocks however will not work on much more than a 750 carb. I have run the new style blocks on a couple 750's and they work very well. The combos are mile SBC running 11.90's and 11.60's. I drill the main wells for anything bigger than 750.
QFT Green Blocks Main Well .164 - .187 Idle Well .096 Cross Channel .161 PVCR .073 Emulsion Blank-.028-Blank-.028 Kill Bleed .028 IFR .043

I've got a set of their red blocks on an old style 8896 1050 Dominator but I can't remember the mapping for those.

Yes the green blocks are QFT E85 calibrated metering blocks.

I have the QFT green blocks and I just pulled the main plugs and I can't get a #2 taper in there. I reamed it for the #2 but it also came with .043 ifr,. 076 pvcr, .028,p,.028,p and these were purchased in may '12. The cross channel is at least .160
