Hi Russ, A sketch of the the spacer would be appreciated, I'm an engineer by trade so making them won't be a problem :) A 2.88 diff would give me 29.5mph/1000rpm :? You wouldn't know how to get the diff out of a Scimitar axle would you? I believe you need a casing stretcher but is there another way ...

Cheers for that Mike

Probably best to try it first, I'm looking for a Jag powerlock LSD at the moment so I think I'll see if I can get one with something close to 3.1 so I have the choice to swapping the cwp around.

These are the speeds from the quaife calculator. 3.3 DIFF Top Gear gives 25.805 MPH/1000 RPM and a top speed of 154.829 MPH at 6000 RPM Engine speeds in top gear:- 30 MPH = 1163 RPM 40 MPH = 1550 RPM 50 MPH = 1938 RPM 60 MPH = 2325 RPM 70 MPH = 2713 RPM 80 MPH = 3100 RPM 90 MPH = 3488 RPM 100 MPH = ...

My tyres are 195/50/15.

I've been using quaifs gear ratio calculator and with the 3.3 diff cruising at 70mph would be 2712 rpm compared to 2942 for the 3.38 and 3205 for the 3:9.

I just don't want to sacrifice to much acceleration through the lower gears but you can't have the nest of both worlds

Hi Chaps, I'm currently in the process of fitting a 4ha Scimitar axle to my Chevette, and was wondering what diff ratio to go for. The old axle was a 3.9 and I was finding 1st and 2nd gear to short, the new axle has a 3.3 fitted bit I do have the option of a 3.58. Engine is a 3.9 Rover attached to a...

Hi, can anybody tell me what size socket fits the nut on the rear of the lt77 gearbox, i need to replace the rear oil seal.

Many thanks

Hi all, just a quick question regarding the LT77 box.

Which boxes have the 0.77 ratio fith gear? i'm looking for one as i need to get the revs down at motorway speeds as i'm running a 3.9 diff in the rear end.

Any serial numbers i can look out for?

Thanks in advance

I've got myself a MSD Blaster ignition box jobbie and need to wire it in to the Chevette. The connections to the coil is simple enough but just need to confirm what to do with the dizzy. My dizzy is a electronic Lucas 35 DLM8 with an ignition module mounted on the side, the - green wire and the + vi...

Right the plot thickens :? I have plumbed the breathers correctly now and the oil sill refuses to stay in the engine :( So i did a compression test and out of the eight cylinders i could only get to six of them as 7 and 8 are tucked under the bulkhead. But the six i did check all gave a reading of a...

Hi V8Chevette. If I understand you correctly you say you have a PCV valve breathing into the air cleaner. This would be incorrect as to work properly the valve needs to be connected to a manifold vacuum point on the engine side of the butterfly. If the PCV valve is connected to the air cleaner then...

Yep that is identical to my problem.

I'll be doing a compression test tonight so i shall post the results up, if you could post some pictures that would be great

Cheers Jonathan

Hi all, I'm having some trouble with my 3.9 RV8, took the car out for a spin at weekend got home and found that oil has been pumping out of the engine around the sump gasket and the back end of the inlet manifold gasket there was also oil around the base of the distributor. I'm presuming this is dow...

very nice, always like to see a sleeper taking shape! can I ask what make is the steering column? The top 2" of the column is Chevette the rest i made from scratch :) I'll do a proper up date on this soon as things have progressed 8-) But here's a taster http://www.youtube.com/watch?v=jaSkHZg-iHg

Loud pipes save lives

Clarkson is dead right, these Rover V8's sound like two fat people mud wrestling in a well. Lovely sound. That is one cool Chevette, a far cry from the asthmatic 1256cc Pastel blue 3 dr my Dad used to have! Very cool indeed 8) Ta :D The missus thinks it's to loud but i'd say it was about right :D
