Need some advice.
I have an 81 2 door in pretty good nick.
I am removing the 3 speed auto abomination and putting in a R380 manual. 5th gear for hwy and maybe change diff ratios as well to drop engine revs. Remove viscous fan for a pair of electrics and lose the twin carbs for a Holley. Bit more power there. Hmm maybe extractors as well. What about sill tanks?
I also want to give the old girl a new paint job. These models bolt together so no so hard to disassemble. I would paint the panels off the vehicle so as to avoid masking. A better job should also result. She does not get used in very rough stuff too often. Mainly long distance touring with dirt.
Q:
a) Should I do the paint myself? I have heard metal roof paint is good. (Roothy)
b) Should I get it done by a pro
c) Should I just read the Sunday paper and forget this whole crazy scheme.

forget the paper , get out and have some fun![]()
The 3 speed Chrysler auto is pretty darn tough, and is ideal for fitting behind some of the larger engines.![]()
Hell yeh them autos are one tough box Go the tourqeflite
I have one behind the 3.5 No Dramas
5 speed is deffinately a better option for long touring though
Leave the car as one to paint (Masking up is easy enough just take a bit of time and it will come out fine)
Headers and Extractors is a grey area and a preferance and will depend on the gains your looking for ( The bigger the flow the more horsepower you need to push the same weight) Ie Loss of backpressure through to much flow
A standard header with 2 and a quarter inch Y pipe and the same pipe with a sports muffler for the rest of the system will do just fine
Can you paint? IF you are good It may be worth a complete pull down and edge it all but if you and average diy painter masking would be quicker and easier for you.
I made the mistake of totally stripping a 4 door for a full respray and its now still in a million pieces as is a lot of work in the assembly, door ,glass interior etc. I bought another Rangie during the process was my biggest mistake and now like it better than the restored one
Read the Sunday paper and then use it to mask up wile you have a quiet beer after you rub/cut it all back
Try to leave the CD's on it as the Holley will be a pig off road.
As Mike said the EFI manifolds flow better than most extractors![]()
If it has a cut up LT95 auto conversion, its most likely a BW35 auto, not a torqueflite as these were in the 1984/85 4door models. Some of the early auto conversions also used C4's etc too.

The Isuzu 110. Solid and as dependable as a rock, coming soon with auto box😊
The Range Rover L322 4.4.TTDV8 ....probably won't bother with the remap..😈
I would of thought the above post summed it up
Too much back pressure results in restriction of gaseous flow (Hence wanting a different exhaust system to acheive better flow and performance and economy in most cases)
To little and the low down response youll need to move a bigger vehicle quicker off the mark and have torque up hill fully loaded is lost which results in poor economy and performance due to more right foot to get the same result as a well thought out exhaust will give
Hope this helps
Cheers Ken
I think he means smaller tuned pipes create velocity that help low end torque and larger pipes can make the air fall into a cavity and cause turbulence etc and make things worse in this part.
I still have not come across Rover extractors that work better all round than EFI manifolds as yet for the above reason. I have tried a few
The typical small tubed extractors seem to rob the top end. I've had a larger diameter set built for my 84 model and it seems to work well from 3000 RPM onward but drowns the low end.![]()
