I think if you can keep the #8 line full under all conditions, it should be enough. Maybe pull the lines off the carb and do a flow check post regulator? See if the results make sense for 100gph through the system, or if it's less. As for the transition lean spot, I've never dealt with alky carbs. My only experience is with EFI. I'd ask the question have you increased timing any for the E85 set up? And are you sure it's a lean stumble, and not related to needing some more timing? Also, I edited an earlier post, not sure if you saw it, don't forget about stoich for e85 being in the 9.7 range. You mentioned earlier shooting for 11.8-12 and that may hurt something.

I am going to do a flow test . I just have to figure out how to measure the pumped gas correctly . What is the procedure with this again? Is it 1 gallon or 2 to be pumped out?

What are your thoughts on having all the fittings in the # 8 line that have a ID size of .160 smaller ? if the #8 line is on the edge of being adequate im wondering if these fittings will be part of the problem? I never realized how much smaller they make them until i had this problem and decided to measure them ..

I left the timing the same . Its locked out at 34 degrees. i do not see that as an issue . The power of the car this way is really good . Once past the bog it frys the tires in every gear . I have to lift . i have 315 drag radials on the car.. The car is very responsive after the bog..

My gauge does not read for the e85 scale . its lambda or AFR. So for stoichiometric in comparison for e85 i just leave the decimal out. So the 9.76 i see as 97 which is not far off from 1.00. but i just leave the gauge set reading for the AFR scale . Its less confusing for me
The 11.8 is my target . The 12.0 is the leanest i would allow it at wot. Thats what i meant . So say im on the lambda scale on the gauge, and im at .81 thats the same as E85 at 7.91 and 11.91 for AFR scale .
