Underwhelming Coronet

HI,
Yes a lose Distributor can do that

 

[#41]

Very nice looking car

 

[Pecos Bill]

Some of the rear ends would have a little metal tag bolted to the center section that id'd the gear ratio. A second tag would designate Sure Grip.

So just discovered the PO didn’t even tighten the distributor clamp ‍
Will definitely take her for a spin tomorrow to see if with the timing set at 34deg without vac it feels more responsive.

Some pics of the motor with filter removed.

The axle is a 741 axle so not likely to be a decent ratio. Something to investigate.

I checked the stall by braking whilst stationary and pressing the throttle. Seems to want to start moving around 800rpm, is this the stall speed?

Well? Any news?

Every 318 i have ever run that wasn't hooked to a 5 speed manual felt sluggish from the stop sign, but if you were cruising at 35-40 and stomped it, it came to life from 40-80 very nicely. Just missing the ft. lbs to push the car with a 3 speed auto from a stop, but plenty of horses once the engine can run it's it favored RPM range.

Curious how the timing adjustment went.

A gear will wake it up. Granted the 318 has a small bore, and is a short stroke. My bet not much over 9.0-1. Yours is fitted with healthy heads, intake, decent cam, and carb. It needs gear to make up for the loss in torque. A 4.10 is what it needs. My bet is easy low 14 second car, maybe even more.

To be able to figure out your gear ratio without removing the 3rd member (you don't have a diff cover on a 741):
1. Rear wheels off the ground/ axle on jack stands
2. Mark the tire on the bottom inside sidewall.
3. With car in neutral, rotate the driveshaft one full revolution while counting the revolutions the tire makes.
- 2 3/4 revolutions: it's likely 2:76 gearing
- Almost 3 revolutions: it's likely 2:94 gearing
- 3 1/4 revolutions: it's likely 3:23 gearing
- 3 1/2 ish revolutions: it's likely 3:55 gearing

You get the idea.

That works if it's a sure grip, if it's an open rear, you have to prevent one wheel from turning. Either keep on side on the ground or have someone hold it to prevent it from turning.

I can tell you from personal experience back in the day you are right on.

Hi all, sorry had some issues that stopped me making progress.

The timing definitely helped, much smoother and generally more fun.

The rear ratio is 2.7-2.9 ish from measurement so not ideal. Issue is I don’t want to lose top end? 60mph cruise is already pretty prohibitive in the uk with 70mph limits and not many coppers to enforce it

Now has some slightly shorter rear tyres too.

Feels like a tuneup is in order, then maybe look at rear ratio and trans. Are there any checks I should do on stall speed etc to check its health?

Out of curiosity, why do you desire to get an approximately top end of over 110 mph. With your speed limits? Don’t know your tire size, but my GUESS would be about 110 mph. There is your top end. But you won’t have much grunt from the line. Hope you achieve your goals.

 

[dubber91]

Hi, no need for 110mph top end. But comfortable 70-80cruise is more than acceptable.

Rear tyres are 27”

What’s the approx rev limit on the motor? North of 3k feels uncomfortable!

We have 275x60Rx15’s on a 8”rim. About a 28”diameter tire. 3:54 Dana.
We run about 3200 rpm showing about 70 ish.
My philosophy is if you can run an inboard outboard GM 6 cylinder, or other brands of 6’s, V8’s at 3500 rpm, why can’t we run those rpm’s on the highway?
We have made a few long distance trips
If you want to comfortably drive about 2600 rpm, I suggest going with a 3:23 pumpkin.
Hopefully someone with far more knowledge will comment. Look forward to them.
