All I can say is the weather is total sh*te in this country, I went home this weekend and was confronted with 2 days of 1.5ºC temperatures, bone cutting winds ands freezing rain. So this pit and garage floor are finally done and boy does it make a difference after 10 years of an earth floor!

Image
Image
Image

I sliced my thumb open doing work on my brothers Alfa so wasn't best impressed, but got the MG over the pit on Saturday.
Image
Image

I have a source for stainless steel bolts now so replaced some of the old bolts and it looks much nicer.

Image

A view from the pit

Image

This shows the final part of welding that needs doing. The rear corner has some rust and at the same time dad is going to re-drill the centralised fuel tank location holes and weld on exhaust mounting brackets for the offside exhaust thats going to be fitted along with moving the filler hole 3 inches

Image

Now on the lookout for a 3.9 motor if anyone has one?

Looking 8-) will be nice to see this finished. Lord Steve is selling a 3.9 for £50 in the for sale section ( sounds like a bargain to me )

I'd be interested:

What else does it need apart from heads?
Where is it?
Pics?
If its miles away could you put it on a pallet for a courier?

Been ages since I updated this:

Car has been in and out of the garage for a while, making space for paid jobs coming in.
Image

View of underneath

Image

As I mentioned before, someone had cut the heater panel out of the car, is should look like this

Image

So dad has been making a repair panel. It has had to be made in 3 pieces to fit it in there, the first part

Image

This was replicated the other side before making a cardboard pattern for the main panel

Image

Before a plate was made up

Image

And fitted into the car

Image

The rear welding got done then, along with centralising the fuel tank filler hole.

Rear quarter, seam sealed

Image

Heater bulkhead now fitted. Anyone know where I can get some dumdum sealing compound?

Image

The filler neck for the fuel tank relocated. There was a slight error with this so dad inserted a blank plate with a hole then welded the original fuel filler hole onto that. It gave him some more spexibility with movement along with better strenth.

Image

Underneath

Image

One of the fuel tank tabs had to be cut down to fit too.

Image

One of the things holding the project up before the respray has ben the final shaping of the scuttle where it meets the wing tops. The wings from the donor car looked better than the ones that came with the new shell so I wanted to use them, but they were welded to the sill instead of being attached by the usual self tapping screws. Being in a polytunnel meant we couldnt grind them off so we got a chance on the weekend to look at them. The drovers side came off with a few small holes drilled, the passenger side was cut as close to the base as possible

Image
Image

Both wings are pretty tidy and more importantly, are unrepaired originals. The others are rubber bumper items with bodged repairs so i'm glad I swapped them. They just need some localised repairs.

Image
Image

Upon removing them, it showed just how far gone the donor car was:

Hope to have more progress soon...

I'm definitely looking at a respray now. So I've decided to bin all the glass bar the front screen and go lexan/perspex. Saves a lot of weight, and means I can touch up the (very poor) bodywork that the previous owner did to fit the sebring arches.

I'm also looking into getting a spit so I can do the underneath properly. Fortunately the one thing the guy did do before me that was useful was chose a decent shell!

I now have a V8 engine, 3.9 litres :D

Bargain off eBay as it had no picture, but the description was detailed enough I was happy it was good. It had done 90,000 miles in a Range Rover and the guy threw in some extras and delivery too.

Image

I will be using a carburettor so wont be needing the injection system. I want to rebuild it so first job was to strip and check it:
Image
Image

No need for the wiring loom
Image

Looking clean so far
Image

Bores are all good :)

Image

Stripped as much as I could over the weekend

Image


Next job is to find somewhere I can dip the block to clean it as, coming from a 4x4 it was quite dry and dusty/muddy

Is that a hotwire system? If so, what are you going to do with it?
Cheers,

According to this link

http://www.v8engines.com/carbs-2.htm#injection-type

You can identify it from the airflow sensor which I dont have, I only have from the plenum onwards. Is there anyother way to tell?

Regarding what i'm going to do with it, the answer is sell it :) That along with the front end parts and pumps I don't need so if anyone is interested let me know.

Think if it's a serpentine engine, it won't be flapper.
