Unhappy Easing around

I have tried everything i think and my 69 just won't ease around.If you pat the gas and ease off the clutch it will die.If you rev it up and pop the clutch it works great.355 c.i. 9.5 compression with T10 4 speed and 3:73 gear.I moved timing up and same thing.Any ideas would be helpful

It could be a clutch \ pressure plate issue. No stick is just going to ease around though, but they all have a sweet spot. Mine will idle in gear around 15-20 mph. Slower than that it just lugs.

Re: Easing around

At slow speeds under 10-15 you will have the feather the clutch.

Gas to rev > ease out clutch> car is rolling > clutch pedal down > off gas > repeat

Option #2 > Install an auto tranny

Re: Easing around

Some clutches are stickier then others also. I have a dual friction clutch because it is easier on the street. My brother in law got a strip clutch it grabs hard making it difficult to drive on the street. Like all above stated standard trannies lug when the rpms are too low.

Re: Easing around

Light weight flywheels also make it harder(aluminum vs steel).

Re: Easing around

Describe how the ignition curves (initial, mechanical and vacuum advance timing info) are configured, and what intake manifold/carb are in use, please. Also, what stick transmission, rear gear ratio?

Hes already posted gears and tranny info.

Bottom line is 900 rpm in 1st gear is 8 mph. Therefore any speed under 8 or in the real world at least 10 or more the car is not going to ease around in gear at idle with the clutch fully engaged.

You can change timing and curves and VA cans and advance stops and idle mixture and manifolds til the cows come home its not going to ease around at 5 mph

That's a true statement. The only exception to that rule was my old 47 Willis. Put it in gear, let out the clutch and it would climb a tree till it flipped over. As stated before , my camaro will not idle under 15mph.

Re: Easing around

With a 3.73 rear gear you should not have trouble starting off without having to "rev it up and pop the clutch". Yes, it is correct, that with the clutch fully engaged, yoou have to be going at least 5 - 10 mph. IIRC, T10 used any number of first gear ratios from 2.43 to 3.4x or something. Do you have any idea what your first gear ratio is?

My 69 with a 70 spec LT-1, high rise and DZ holley carb, 4.10 rear and M20 trans will take off without even touching the gas if I let the clutch our easy. I realize those are different numbers than you have (well, maybe the same overall ratio depending on your first gear.)

Would be nice to get more info.

1st gear ratio?
what kind of clutch? Not just the brand, is it a diaphram type? They tend to be much easier to ease into.
As Dave suggested, what is your initial timing at? How is vac advance (if you have one) hooked up? Manifold or ported?
And, the carb and intake COULD be a factor.

Give us some more info, and I bet someone will have experienced something similar.

Re: Easing around

Best i remember it was a old dirt track car flywheel and pressure plate so it would be lightweight

Most types of questions are designed for that specific use and not typically very good on the street where youre easing off from stoplights backing into parking places and things like that.

I would change the clutch pressure plate and flywheel

Re: Easing around

Interesting, is it too light a flywheel, or, engine tuning way off? Guess we'll never know, will we.
