I listened to the Edelbrock tech guy and installed the 43 squirters. Put back the stock jets and rods. Stumble is gone. Runs super. Went with yellow springs as i have just barely 10 inches of vac at idle in park. They were right, off idle stumble is a lean condition, needs more squirter. I guess thats why they have a tech line.



So are these larger "squirters" or larger pumps?? Do you get more volume with these over more pressure?

I upped my carter, on my 440, to the hole in the arm, closest to the piston and its better, but still seems to have some initial bog in it.
