Thread: 4.6 into '81 two door

......sorry it took so long to get back to this, bit busy.....so, my next question would be....is $800 a reasonable price to pay for an unknown motor and maybe a pair of seats ( I think thats about all I may be able to swap over from the '96 )

Trying to find information on the auto choke original set up was near on impossible .... with the original auto choke being plumbed into the cooling system using a heat sensitive spring that operates the choke.

They didn't work well when new and most were converted to manual (there was a kit available once) but thats long disappeared too.

While they are a good carbie for 4WDing .... the availability parts .....knowledgeable people (still alive) to tune them are getting thin on the ground.

The previous owner of my 2Dr classic tried to convert to manual and didn't work out well ........thanks to Meccles (Mike) who sent me his 350 Holley and manifold which I've refurbished and fitted to my 3.5V8.

I've run it once or twice since fitting it but haven't run it often because of a rattly piston....and is awaiting a rebuild but it was excellent

Funnily enough .... while surfing YouTube the other night I came across some guys on a site called "Road kill" where they fit one of those new a fuel injection systems an old V8 while on a 1000 mile 4 day road trip.

The system was very simple, they fitted it in a car park .... on the side of the road ....and it started first time .......definitely worth looking into as an alternative to a straight carbie set up.

Goodness me, that's surprising to read. I've found four NOS CD175s on eBay over the years and they've been fine. They are an incredibly simple and easy carbie to work on. Mine are on a 3.5 but they have been used on a 4.6. Someone here put up some information about what had been done to theirs by a specialist from over east. The pistons and needles were modified somehow.

Because of this, I'm planning to use SUs should I manage to get a 4.6 because there is more information out there, and it sounds like they only need a needle change.
