360 LA installing Promaxx Aluminum heads
Long day with the carburetor... but yielded really good results. Lots of swapping and tweaking.
Engineer who decided to put so many tiny E-clips on the carb needs a stiff kick to the junk... there's gotta be a better way. :icon_fU:
^^^ A couple of those to remove and reinstall with every adjustment... one right over the pass side metering rod. You can choose what end of the choke rod you wanna take the e-clip off of... they both suck.
If the carb is on the car and that lil clip decides to go flying it goes into the engine compartment never to be seen again -or- into the carb. If I was doing this a lot I'd be drilling tiny holes for cotter pins.
If anyone else owns one of these I'd recommend getting a few extra e-clips, the 2 gaskets and this kit at a minimum before tearing into it. Demon comes pretty fat out of the box. Unless you have a lot of cam and compression.. you'll wanna thin her out a bit.
One other thing I noted (but apparently did not take a photo of) I was probably working against was the heat plate/shim Holley provides. You sammich it between 2 carb gaskets under the carb. It's supposed to help with heat dissipation, that's debatable. But what it does do is make setting the curb idle more difficult as the plate extends past the gasket where the idle screws venturi are. Once I removed the plate the curb idle mixture got easier to adjust.
Anyway here is what I started at wayy fat:
76 primary jet
64-56 rod
Green Spring
Here is where I landed pretty happy:
-74 Pri jet
80 to 78 Secondary jet
60-50 rod
green spring
AFR results:
Idle 13.5
Tip & light load uphill 11-12
WOT 10.8 to 11.5
Hwy 13-14
No bog or hesitation at all. Eyes burn from swimming in gas vapor all day but I'll sleep better tonight with these results :)
