clutch Z bar

I am converting a 65 Biscayne to a 4 spd trans. I bought a Z bar at a swap meet that has a 1: 1 ratio(both arms are the same length).

Being 73 yrs old I want to minimize the clutch petal effort.

I want to make the input arm longer......anyone have a zbar from a SBC they can measure the arm lengths.

thanks Don

drill time

When I had the Buick nailhead and a BW T 85 Od in my willys I drilled a few more holes in my z bar then moved the linkage hook ups around until I got the effort and pedal at rest height I liked.

Hey Don, you're CLOSE, I used to work at St. Cloud Texaco. Have you considered going hydraulic?

I did hydraulics on my cobra, but found no advantage to it & the cost is higher.

The Moore family still own the Texaco? That was a long time ago...

Don, if you still need the arm lengths, let me know and I'll go out and measure one.

I'm running about 7:1 ratio in my T , w/B&B pressure plate , ratio seems within reason & I'm 63. The type of p/p you use will make more difference than anything IMHO

A fairly stock replacement Diaphragm type pressure plate is all you will need.
No matter what you do--you will still need to maintain about 1" travel at the end of the fork.

Messing with ratios could make this impossible.

Clutch in my old Chev truck was a bear with the 12" Borg&Beck.
Like pressing a marshmellow with an 11" Diaphragm

I am using a hydraulic clutch in the 59 Elky----88 Chev truck master with an 87 bellhousing and slave-------pretty easy operation---but a pain to bleed.

Have a 10.5" Diaphragm in my 66 Elky with stock ratios and it is pretty easy to operate.

Nevermind- I was talking about ca. 1970-ish.

easier pedal

I broke about 20 bones in my left foot-ankle, My F 350 dually is tiring and brings back the limp , one of the tractors is also hard for me to drive. I redid one car that I had put in a HD clutch, changed the ratio and reworked the pedal stop to have a little more travel with less effort.
