stagger jetting for stock DZ302 with headers?

[x33rs]

I've likely went over this before, maybe here, not sure.

Yes stagger jetting for the DZ302 if using the stock intake is worth while. I have mine stagger jetted and this particular intake likes the driver side up on both front and back. How much is dependent but I found on mine it liked 2 sizes up on the driver side.

So for me, I'm running headers and a 2 1/2" mandrel bent Pypes transverse exhaust system. I'm also up at 5,000 feet elevation and I routinely drive down near sea level. So I look for a happy spot where the AFR's are a little richer up here, and still safe at sea level so I don't have to keep opening up the carb.

I run 70-72 front and 76-78 rear, with the passenger side of the carb having the lower jetting. I keep both power valves at 6.5
This keeps the engine a pinch on the rich side up here but nothing horrible as the plugs look nice and it still returns good mileage with DA's in the 7,000 foot range. When I drive down to sea level where DA's are around 3500 feet everything is nice and happy.

Great thanks - thats pretty much exactly what I was thinking -
I have 72-76 now in it - so a little tweak should help

Thanks

72-76 square is a pretty good spot to be, these engines respond to it.

I assume you are somewhere near sea level or where DA's don't get out of control. If so, and with headers and free flowing exhaust, it will likely respond to 74-78 on the driver side.

I'm in Michigan - so we're at or below sea level LOL
