First off what year of car are you working on?

I’m working on a 71 Series One XJ6.

I figured out the bracket mounting stuff. Now I have more questions :slight_smile:

The speedometer cable doesn’t appear to be long enough. It also emerges
out
the passenger side of the tunnel. Do I reroute it through a hole I drill
in
the driver’s side, or get a longer cable?

How can you tell the speedometer conversion factor? I looked at the face
of
my gauges, and didn’t see anything telltale like the Suncoast kit said I
should. I’m assuming the two likely answers are 940 and 1000. I’ve got
the
gear part numbers ready to go, and will be heading down to the tranny
shop
once I figure out the conversion factor.

Does anybody have a picture of the tranny cutting? The dust cover
mounting
screws are pretty darn close to the outside of the tranny. Do you just
the
tabs above it out?

Thanks. I appreciate all the help and support. John Cadwell

I have a 71 XJ350. My cable was disconnected when I bought the car but it
appears to go the normal route. For me all I needed was a 90 degree
adapter
at the trans. I was fortunately to find a disassembled unit in a box in
the
truck and made use of that. 45 degree would be better actually. Do you
have the adapter? If not I think you need a slightly longer cable, or an
extension. Any speedo cable shop should be able to make something.

Anyone have some info on converting 78 XJ6L to a GM350TBI crate
motor? The JAGUAR had an engine fire so I’ll have to trace some
wires down. I plan to use a John’s Car Conversion kit. Thanks

  • ----- we all have info in doing that conversion. The wiring is half the
    fun.

Some of you will recall that I posted a question a while back about
the problems I was having with a TH350 I installed in my car.
Well, it turns out that the transmission was badly rebuilt. I
returned that one and got another rebuild from a more reputable
source (not some guy on eBay, this time!)

Everything seemed fine until I took the car onto the highway. It
seems that my highway RPM is higher than it was before, and I’m
wondering if this is a transmission, converter (or maybe even
speedo) problem.

With a 1:1 ratio in top gear (and I know it won’t be exactly that
due to some slippage in the converter), I calculate that with a
2.88 rear-end and 215/70R15 tyres at 70mph I should be showing
2500rpm. However, I’m showing 3000rpm. Could stall converter
slippage account for that much of a difference?

I used a B&M TorkMaster 2000 (following the recommendation by
John’s Cars to use a slightly higher than stock stall speed
converter). Did I go over the top?

I’m hoping that the speedo is at fault, but John’s gave me a green
drive gear and a blue driven one - which are correct for my diff
and tyre sizes according to the lumps web page that has a
calculator for these gears. I wondered if I might be mistaken
about my diff ratio, but if the ratio were actually numerically
higher than 2.88, that means that the speedo would be reading
HIGHER than my actual speed, so the discrepancy is even WORSE!

HELP! Am I looking at my 3rd transmission in 2 months?

Thanks in advance,
