Does anybody know what size bolts to use for motor mounts and an automatic crossmember? Im changin from the 6 cylinder spot to the 8.

Tx Firefighter · 01-03-2004, 10:40 PM

I used 3/8x1 inch bolts on my crossmember. That's what it came with stock, so that's what I replaced them with.

Just make sure to get good grade 8 hardware and get castelated nuts those are nuts that have three indentions in them to keep them from backin off kinda like them plastic lined locknuts but work alot better.

Tx Firefighter · 01-04-2004, 08:56 AM

A castellated nut is one that has notches cut out of it for a cotter pin to go through. They look like a castle is why they are called that.

There are 2 kinds of self locking nuts:

-nylon type- has a nylon ring inside of the nut to keep it from turning easily. To be used in any application subjected to up to 250 degrees F heat.

-hi temp self locking nut- has the indentions in the nut to act against the threads. To be used wherever a nylon lock nut would fail do to being subjected to heat.

A castellated nut is not a self locking nut. It is built to work in concert with a cotter pin for securing it against loosening.

Ode to a Castellated Nut
A Poem
by Gregg G Guydish
© 2002

I gaze upon your steely walls,
That hold your keep secure,
Hexagonal battlements,
That protect which you hold dear.

Bind that stud close to your heart,
Safe within your keep,
A holey task you must preserve,
For to lose it is to weep.

But man is stronger than mere bands of iron,
And he pries your merlons free,
There to wrest you from your grasp,
Ignorant of your quiet plea.

Though your defenses have been breached,
And your ramparts so assailed,
You will resume your silent task,
Or my steering will be failed.

Spun again onto your home,
Lo these twenty years past,
I torque you up nice and tight,
So continue, you may be, to last.

As I cinch you down to your prescribed FLB,
And align your crenels with your hole,
I ponder the battles your walls have seen,
Time, and elements, that scathe along your boll.

Here beneath my merry chariot,
You labor valiantly to hold,
Against the onslaught of nature and earth,
Persevering through the heat and cold.

But just to be certain that you do not fail,
I slip in the pin and so it arose,
Then bent it over and secured it,
With a bang across your nose.

Tweak the Holy Holley
Carburator is my name.
But what is my game?
If you know not a Holley
Then you know not my fame.
We are very small and stubby
with a funky yellow body
I travel to and fro work,
By providing fuel to your head.
Ricers, little do you know me
Because your motors are so fugly
That it is truly we that make the power
But what would you know of me
you drive a gay toyota camry
They ask, What is to become of me?
An answer for them I have not,
For you alone can save the holleys.
BUY AMERICAN AND SAVE OUR HOLLEY
