What Did You Do To Your G-Body Today? [2022]

[UC645]

Speaking of exhaust- learned that I can’t measure for sh**.

Now the Powersticks won’t fit unless I put dumps on them, or I re-engineer the whole tailpipe setup. I’ll hold on to them and probably weld V-band flanges to both ends after I cut off the slip-fit ends.

And the cherry bombs won’t fit without trimming, and I need a set of center/offset mufflers to put the tailpipes in the right location.

Them rear coil springs....

Made a tune adjustment on the idle parameters since we've had some colder weather and I can dial that in now.

All slicked up for the car show tomorrow.

Colder weather?

Got into the 40s, haven't had a chance to log in base running air flow in that temp

Wow, it gets cranky at 40? I'm waiting for a 0ish degree day. Coldest I've logged desired/measured airflow so far is 18 degrees. I think I'm on revision 3. Next step in lieu of colder air is unplugging an O2 and watching it in open loop up to about operating temp. What's happening is it hits closed loop and my cold fuel adder drops off the face of the earth. After watching how long a piss warm restart takes to re-enter CL, I think this will help fix some random crappy restarts I'm experiencing in my 1500. My idle airflow does a great job of applying trims, try logging cold start AFRs and see if the motor doesn't just want a little more fuel as it's warming up.

I'm sure you know as well as I do how many tables there are to play with. Cold fuel table is there.

I had my Base RAF close for anything cold, I was off by like 2% which isn't too bad. I have the whole table scaled. My car ran great I just wanted exact numbers.

You can run OL without unplugging O2 Sensors.

Out today at a local show

I verified I needed an additional 1/4" or so of oil pan clearance - all set now.



I think this is my sign to not lower the car

test fit the new 4-row radiator for my 454 swap. Added some stiff foam to cradle the rad on the mount, and the shroud snuggles up well with a litte trim off the top. I have to say, 454 engines fit tight but good in these g-body cars.
