Lol I may be that guy who needs to know why. You know....for science.
A few of you mentioned it earlier. It just never made sense to me that it was so violent on one side and not the other. I'd still like to...
Well interesting find tonight. After moving my test pipe with the wideband to the driver side this week I only had a chance to run it at idle....
I'm still wondering if maybe the intake gasket is cracked between 2 cylinders but I feel like I'd have a backfire on both then. If it was...
So far the only real money spent that was unnecessary was the MSD distributor and some extra spark plugs. All of the carb work needed to be done...
As Budget said this is a good rolling log for me to look back on and see what I've done so far and what results I had. Like the couple weeks I...
For anyone still following this never ending story I swapped the wideband O2 over to the side with the backfire this afternoon. It's raining here...
Ok gentlemen I got a test drive in today. Largest jets I ordered for my ends was actually 67s....place I got them from didn't have 68s. First...
Been doing some reading and seems like most dyno testing with Vortec heads shows they make the best power in the 29-32* total range. Not saying at...
I'll bump the total timing for the potential performance gain. I definitely had it that high during testing at one point and it didn't fix the...
I'll see what the next size stop bushing for the distributor would bring me to
More timing for what? I've thrown more timing at it before and it didn't solve the backfire. Only thing I can see it helping now is the bog in...
Got my 56 jets today, installed them, and reset my idle. This may be the correct jetting for the center carb. Idle is around 14.5, acceleration...
Decided to change gears for an hour today and go back after the exhaust backfire but had no luck. Put a vac gauge on it and it still floats about...
Because of the space constraints I can't really in reasonable the pedal travel. I can live with it how it is....just seemed interesting/odd that...
Never underestimate adequate sleep hahah. I've been burning both ends of the candle and the middle for over 15 years now. I'll reread your post...
@carbking thanks for the clarification on RPM ranges....I couldn't find that info anywhere. As for checking the 2nd link in your signature it...
I'm continuing my never ending quest on trying to dial in my tripower on my crate engine and feel like I've watched just about every video...
Just thinking about something @carbking mentioned earlier. Jon it seems like my rich cruise is likely from being in the idle transfer slots even...
Already is
Went back to idle fuel restrictors that are around .029 today but kept the 57 jets. I'm pretty happy with the numbers for the center carb...
Just went for a ride with the opened up IFRs and with the 58 jets it was pretty rich on acceleration....dipping into the low 11s. I threw the 57...
We smoke tested the exhaust on the driver side last fall and aside from the carb butterflies and bowl vents we didn't notice smoke coming from...
I swapped to a whole new distributor, cap, and rotor last fall with no change. Going to check plugs and wires on that side again tomorrow...
Been swamped with my regular job, yard work, and a customer job in my resto shop but managed to open the IFR a bit Monday. I went from .0292 to...
Apparently there is a ton of debate about this topic online. It does in fact smell the fuel mixture but my understanding is it reads the oxygen...
You sure? Oxygen sensor measures oxygen, not fuel. I'd assume unburnt fuel and unburnt oxygen shows lean on an AF meter.
Just got a decent drive in with both end carbs bolted up with no fuel. I'm fairly pleased with everything. Idle AFR is right around 14.7-15.2...
Put the rear carb on before and adjusted the idle screws and went for a ride. Everything else seemed to stay the same. May still be a little...
Early Bronco rear with 3.50's
