It's all in the timing!

[FuzzFace2]

I think we picked 62 MPH as that is the speed David typically drove. But he may remember better. (I think my memory used to be better, but I really can't remember.)

I think yours is better than mine

That would make sense if he drives that MPH most of the time.

I also want to say the peak TQ was around 1800 RPM?

I know at 55 MPH mine in direct drive is 1800 RPM and in OD that same RPM is 70 MPH, the speed limit here (not that anyone goes that slow).

Actually, it is a bit lower than that in most cases:

Ok so between 1200 & 1600 rpm depending on what type motor tune from the factory.

So David is just at the sweet spot at 1400 rpm at the speed he travels at.

I was sent a text on the spring kit it is Mr. Gasket #925D

Now to find one when I get out of work.

I enlisted the recurving assistance from someone specializing in that. He asked what modifications had been made to the exhaust, what transmission, rear axle ratio, weight and whether or not it had EGR.

The later heads [1984(?) and up] were fast burn designed] and much more sensitive to the absence of EGR.

Thanks for the information.

Wonder if my motor is 1984> with a fast burn head?

I also don't run a EGR, I hear it helps cool down the chamber to stop knocking.

With no valve and the head that could be my issue right there?

If the weather is in my favor tomorrow I hope to get some timing / RPM readings.

I was in the parts store today and forgot to check on the spring kit

I would like to have it before the holiday as that might be the only time I have to make the change.

$7.50 part and $10 to $12 SH fee through the 2 on line speed shops

I will have to see if local dose the same.

The exh system was a order and they charged me for it.

On a side note I have a hand full of dist. springs from my MSD dist. wonder if they would work?

Going to dig them out of my "pit box" to see what they look like and fingers crossed they will work.

They might work. You can check their tension by hooking one of them to one of the existing springs and pulling to see which one gives first. Obviously that is the one that will let the timing advance faster.

But, there's also the length. IIRC, one of the springs has an oversized loop on one end that lets the other spring control everything until you hit the end of the loop So the length has to be right as well.

So I have to pull the dist. and pull it apart to check if the springs I have will work, great

Yup. Welcome to Ford distributors.

Yup. Welcome to Ford distributors.

The man who did my distributor is named William Ambler. I came to know him on another forum, years ago. His email address was/is billythedistributorman@live.com. I believe he went by WSA111 on the forum.
