Hey all,
Am wondering what the Standard diff ratio was for a Holden Running a
power glide geabox, talking HK HT HG series,
but had an idea of fitting a Glide to a 2 door torana,
This is a project idea for a 1/4 mile runner.
Also
Was there a different ratio from the V8 and Glide
to the 6 cylinder and Glide.
Cheers
Chris.

6 cyl were 3:08 ratio, thats what I remember anyway

regardless its 1 to 1 final drive.. just like traumatics,turbo 350,400's
Unless you making good torque dont go for the glide for the plain reasson its only 2 gears

If you have no torque, you need ten gears not two. But since big chris hasn't mentioned what engine he intends on using, the Power Glide may be fine.

thanks guys,
is an open ended plan atm,
Like I posted in the other thread about the jag diff,
am looking at picking up a damaged car for parts,
then assembling a drive line into a UC hatch body,
So the next thing is to find out standard Jag diff ratios.
one engine idea is a 4.2 litre Jag OHC 6 cylinder,
with some form of forced induction
Just kicking ideas around.
Cheers

I thought the trimatic was introduced on the HT, or was the powerglide still there for v8's?

According to my records HT was on the "cusp" between HK and HG. 2 sixes, 4 V8's and 5 trans. inc. power glide and trimatic.

Hi Guys.
The 6-cylinder HK/HTs with Powerglide transmissions normally used a 3.36 rear axle ratio.
The Powerglide was introduced in the HD series (1965) & was replaced in very late HT series (around May '70) by the Tri-Matic for all 6 & V8 engines except the 350 in the Monaro GTS. It was still used in the HG Monaro GTS 350 auto.
Rodomo, the number of different engines & transmisions etc. in a given model depends how you differentiate them. If you just count cubic inches then it's 3 sixes, 4 V8s, 5 transmissions, for the HT. If you count all the different compression ratios & gearbox ratios, then it's 12 engines (6 sixes & 6 V8s), & 7 transmissions. HGs have 15 engines (a Holden record), but ony 6 transmissions.

the jags were high on torque but low on revs if i remember right
if this can be confirmed a high ratio like 2.78 should go nicely

I have a glide in mine with 4200 stall and the cars pretty light, would not go that way again need more gears. Unless its an LJ or lighter go a 3 speed minimum, I have 3.9 to 1 diff and 27 inch high tyres and 1st gear to top gear is too much of a difference in ratio for power delivery.

Could be anywhere from 2.9 to 3.5 depending on year and transmission(overdrive etc)So the next thing is to find out standard Jag diff ratios.
You need to know what model the diff came out of or just establish the diff ratio by hand if you have the possible diff in front of you.

I would definatly look at something else than a Jag engine. One of the main reasons is they are v-e-r-y heavy, they didn't have the thin wall casting techniques back in the 40s when the engine was designed, they're very prone too overheating and yes they have a big long stroke which doesn't make them a revvy motor. A big block chev would be lighter. Also you would have to fit a big bulge in the bonnet to fit it in the things are huge.

Hey thanks guys,
summary of jag engine,
heavy,
big torque,
no revs.
was talking to a mate about the UC 1/4 mile idea,
he said, this is coming from a GT Falcon owner,
"If you want to rev it, Chev it"
More research required.
Cheers again

Hi Rodomo.
130 ci, export only, used from HT to HQ & LC/LJ Torana but as I said export only.
The motor is listed in all the Australian owners manuals & other literature.
Could you imagine an HT/HG/HQ with a 130 ci 6-cylinder, it would be a bit gutless eh !
