This may be hard to diagnose without experiencing it first hand but when I drive my "65" 327/300 on the highway and hold it at speeds of approx. 65 or higher, I experience a slight, steady hesitation in the engine that I don't experience at slower speeds. I always run high octane/Sunoco fuel and recently had a new carb put on it. Has anyone ever had this problem or have any ideas? Thanks, Ken

Re: Engine Hesitation
your timing could be too advanced, fuel filter, cap, rotor, wires, plugs. all could cause this problem. -
Re: Engine Hesitation
Could be lean. So tell us about the "new carb". Exactly what is it - a real Carter 3721SB or some one size fits all generic replacment?

Re: junk edelbrock afb
i forgot to say if you put a new edlebrock afb on you might as well throw it in the garbage as these carbs are junk!Comment

Re: Engine Hesitation
Ken, start with the easy stuff, like a bad plug wire or worn points, rotor and cap. As one stated check the timing. May even be a bad plug, read them after a highway drive. Is hard acceleration OK? If it is, lean condition is more likely.Comment

Re: Engine Hesitation
Ken:
Hi speed "surge" is usually caused by fuel starvation. Check your float level, and/or anything that might be causing restriction of fuel delivery to the carb. Your fuel tank should have a vented cap.

Re: Engine Hesitation
Thanks to all for the advise and responses.
As for the carb and acceleration, the carb is a new Holley/4 and acceleration has been great since I put it on.
As for the other suggestions, I will follow up on them all before I store her for the winter.
Thanks again!
