Hey
418 SB on E85, Big badass drag engine in my 67 GTX
Big stumble off idle, can't get it out adjusting pump.Went from 33 to 45 squirter in front and back but still won't take a quick pedal.
It has RED cam gear in it. I have the Holley package.

Which one?? I see the chart white to pink (don't need brown)
Green gives the biggest shot of fuel??
Actually Blue is the most aggressive profile though, isn't that correct?

Which cam and which selection hole #1 or 2 should I try ??

What spark plugs are you running.. they might be to
cold

Hey Mr Peabody
got a Champion C59 YC plug. Not sure if it is hot or cold. I just always use that number or a cross over brand

just pulled the old cam out. it is PINK

"" Big badass drag engine in my 67 GTX. Big stumble off idle, can't get it out adjusting pump.""

The 30cc pump cam sizes (largest to smallest VOLUME): Blue, Orange. Green, Pink, Red, White, Black.
Since the Blue has the Largest volume of the 30cc pump cams, give that one a shot on hole #1. Then if you need more, then you might have to test a 50cc pump assembly.

That Pink cam is the laziest of all of the pump cams off idle even though it is the fourth largest pump cam in volume. Blue and Orange are the most aggressive off idle and then Green and Red,

Thanks for tips

Just put the Blue cam on and adjusted air screws.
Running super good now. it was starving.
May still go to a bigger sqirter. I see nothing wrong with a 52 or 55.
It is taking excellent throttle now, even running cold.

Quick Fuel factory settings extremely mild. UGH

Also, are you using the hollow squirter screws with
the bigger squirters

timing?
