Arrow problem with 350 sbc

I have a truck with a 350sbc in it and some mornings (not all mornings) it idles good while warming up and then it spits and sputters. I can give it a little gas and it runs fine, but then idling it runs roughh and sometimes shuts off. I can then restart it and it may run fine. It's wierd! Any ideas what it could be? I was thinking maybe the carb, but I'm not sure.

It is a 1980 350 sbc with an Edelbrock 600cfm catb, stock heads, Weiand aluminum intake. 278 duration cam with .467 lift and 222@50, Accel HEI Super Coil and 8mm wires with Accel shorty header plugs. The lower half of the motor is all stock.

Thanks for any help!

Edelbrock 600's come with a electric choke and the less expensive ones do not. Which do you have?

If it is the one without a choke..... the temperature (outside) could be the reason......

It is the one without a choke. It never did it before, it just started doing it. <img src="graemlins/boxing.gif" border="0" alt="[boxing]" />

Edelbrock/carter are good carbs but I have heard they have had problems w/flash. A pc. of flash might have broken off & is causing you trouble.....Don

EGR or Non-EGR intake? cold weather can make them stick and act goofy too. That can really hose up your engine's dropping back to idle from partial throttle.

It has the EGR port, but I am not using it. I am going to buy another intake that doesn't have the EGR though.

I do not know how cold it is in your part of TN but it is getting colder (winter time). When you restart it, more warmth is in the motor.

I have the same situation with the 750 Edelbrock on my 32 Roadster. Never a problem in the summer. When the temperature drops, it needs a choke!

Without a top...see the photo.... I do not drive it much when it is cold!
