Default HELP! How to adjust valves on a 289....plus more

Finally got the 66 Mustang to fire up today after 2 days of going back and forth to the parts store (including a new carberator).

I now have a few more questions.

1) How do you adjust the valves on an overhauled 289 engine?

2) I need a linkage arm that goes from the carberator to the accelerator arm. Does anyone have a picture of one of these on their mustang so I know what it looks like (or know of anywhere on the internet with a picture of one)?

3) Where does the vacuum advance hose hook to? It goes from the distributor to the ______________.

4) Finally, I am not getting any electricity to the coil. We made a hot wire so we could fire it up. Any suggestions on an easy way to get power to the coil?

Thanks for all your help in previous threads. Hopefully this Mustang will soon be on the road. I thought we'd be driving it a little today. We're just hitting a few glitches.

1. Ford Mustang Service Manual.
2. NPD 2007 catalog pg 96.
3. Base of the carb - but depending on you telling us what engine - who knows -
4. Get a wiring diagram.
Glen,
I would rather be on the outside shooting arrows in -
(it's more fun)

The valve would be adjusted by torquing the rocker arms to the specified torque setting unless they have poly locks.

When adjusting the valves, does the engine need to be warm, or can you do it without warming up the engine?

IHAS to be cooled down.And remember (as im assuming u used hydraulic lifters) that ull get some bleed off so tighten then wait and tighten again...

Hi guy.
I recently got a '67. And I goota tell you, I am not any kind of expert!

But, your 3rd question, 'Where to attach the vacuum advance', is a problem I also had in the last few weeks.

Mine was attached to the BASE of the carb.
But I found out that there is a ported attachment on my carb that is made for the distrib vacuum advance, and that vacuum port is located up on the throttle body, not at the carb base. Mine was set up wrong.

The carb base is a Full Manifold Vacuum. The port up on the throttle body (on my carb) is made for the distrib vacuum, and it senses the amount of vacuum that exits above the throttle.
Look into this.
For instance: At idle, the throttle is closed. The Manifold Vacuum is at max. But the upper vacuum port (again, on my carb) is zero. So, do you want your distributor advanced at idle?
Other issues also exist: highway cruising at partial throttle, and those times when you throttle-hard to pass, etc.

Check it out. And good luck.

-Mark

Ok - I just rebuilt my 289, but as you can see from my latest post, I can't get it started so take my advice with a rain of salt.
I just followed advice on this forum and on several books on rebuilding engines to adjust my valves. (Chilton's, How to Rebuild your Small block Ford)

My engine uses hydraulic lifters.

Basically,

-prime the lifters (squirt oil into the side of the hydraulic lifters until they flex and pop oil out of the top),
-place the rods in inverse to the manner in which they were removed (upside down) because the rods wear differently on the top and bottom
-place the rockers on top of the retaining screws, place the guides in the rocker arm cups and place these over the retaining screws.

-tighten the hold-down nuts on the screws until you can't freely spin the pushrods (tight spin with a gloved hand)
-tighten a further 3/4 turn on each screw.

IN THE FOLLOWING ORDER

In TDC 1: #1 Intake (Tranny side - TS ) #1 Exhaust (Front of Engine - FE)
#7 Intake TS #5 Exhaust FE
#8 Intake TS #4 Exhaust TS
180* off TDC 1

#5 intake TS #2exhaust TS
#4 intake FE #6 exhaust FE

270*off TDC 1
#2 intake FE #7Exhaust FE
#3 intake both #3 exhaust both
#6 intake TS #8 exhaust FE
