Everything in that image other than the engine block+head. You will need the sump, water pump with pulley and also radiator and hoses etc. Best to get a scrap car with good running gear to make sure you have everything you need.

Is a lumpy bonnet required for a redblock?

Personally I'd go with the B234 in the 343. then turbo later if you want more power. The 300 gearboxes don't look much different to the big volvo M4x ones, just turned on their side with a different front plate rather than a bellhousing and a diff stuck on the back. A 360 donor car would be really useful if you could get one, not just for the parts but for reference when it comes to mounting 360 parts into the 343. FilthyJohn on here has put a redblock motor in a 340 at some point so it can be done, custom mounts would probably be the easiest. Another thing to bear in mind is that teh 343 is carb and B234 is injection so fuel pump will need to be changed and possibly tank, although the valver people manage to use the 340 tank rather than swap to 360.

I think the rule of thumb is you need an in-tank pump for top access carb tank or the bottom outlet GLT tank for an in-line pump.

I wonder if a ridgid tank to pump pipe would solve the carb tank with in-line pump problem, but I guess you might have a priming problem then. Although priming seems to OK with a flex pipe, we are not entirely sure why this doesn't work, my theory is pipe collapse or cavitations due to input suction.

So, to clarify the situation: I would need 360 because it came with redblock? Though the axle, gearbox and torque tube are basically the same, their proportions are different design wise? Lengths between different parts etc?
I could take starting from bellhouse, torque tube and gearbox from 360 and it would work out?

I fIgured I could get running 360 from scrapyard for couple hundred euros, so thats no problem.

In what extent the parts are interchangeable between versions through the years? Like could I take headlights from later versions and mount them to my 343(current headlights are not usable)?

Are the wheels from 200/700 series usable under 300? Could I take brake disks etc in a long run and use them? I like the braking power of 740 GLT :)

Btw, yes the 700 sees has two fuel pumps. We have done it many times that we have taken the in tank pump out. They are the first to malfunction generally in fuel supply and as they start doing it they make this loud whiny noise which is annoying. Second bump is not under bonnet but under the car in the middle of it. For NA and light turbo it appears to be totally sufficient, we have run dyno and seems to work out fine. So I guess taking the bottom fuel bump from 740 and leaving the 343 tank would work ok?

Easiest place to start.

No, no, no. Quite different.

The axle is similar. I think the body to axle location bar is different? 343 has smaller rear drum brakes? There is no torque tube on a 343, it is a hollow aluminium propshaft with bonded rubber couplings.

More or less.

Headlights >MY81 are one type, MY82> are different.
Wheels on a 200 series are 5 stud, not 4.

There's a reasonable amount of interchangeability between types, but the usual Volvo change something every year thing.

You can use the wheels from the 400 series if you wanted bigger wheels.

Thanks guys,

it sounds like...I would really have to love the 343 body. Since it sounds easier just to swap redblock to 360 :=)
Before diving in, I will do a research in local scrapyards, how common is the 360 and 343 for scrap parts. I am going to need them anyway sooner or later.

As the 740 is only usable for b234f motor, it would make sense to install another engine to it, to keep the car running. Pointless sending it to scrapyard since it would run another 5 years probably without investing any work to it. Although the return money could be considerable considering the weight :)

EDIT: how can I make sure from which generation my 343 is? Vin code says it is from 1980. Is it Mk1 or Mk2? I hear that there are difficulties getting spare parts for Mk1. My vin code is: XLB343511BC554106

If you can find a 360, pop the b200 in the 740, take the bellhousing and torque tube etc from the 360 and stick it and the 234 in the 343 ... and show some of the more expensive cars on the stage what a volvo can really do :D

Wheels can also be taken from mk1/2 vw golfs, polos (up to 2000ish), corsa/nova, bmw e30, suzukis and some toyotas (starlets mainly) to name a few ....

Sounds like an interesting car in the making, keep us posted if you go ahead

Thats good news, since my old man used to have also Mk2 golf GTI which is standing there and has few alloys! God to know there is a good choice of wheels, 200/700 and more modern volvos are not to keen to fit other brands and choice is quite limited.

I got a offer to following car. Seller says it is a 360, but after vin code request I figure it is not a 360 at all.
Here is the code:XLB343213FC074441

I guess that would not help me out? :/

Once I get this small questions solved and I am confident to start a project I will start a project thread and keep everything in there :)

You figure wrong.

34 = 300 series
3 = 3 door
21 = B200 K/S
3 = 5sp manual
F = model year 1984?

Sounds like a 360 to me.

OK, that is interesting. But I am curious how do you recognize it is 360, because of the motor gearbox combo?
Looking at the Volvo 300 vin code explanation page here, it says that three first numbers are vehicle type identifiers.
http://www.volvoclub.org.uk/vin_300.shtml

There is another issue. In our state, motor replacement is limited only to those engines which have been installed to that series in factory. For example I could take and change one redblock engine to another but as 300 never came with b234f I am in trouble here. As i understand, they have this limit so that engine mounts would stay the same. There is option to install any engine to any vehicle in some extent but if I start messing with engine mounts I would have to pay beefy fees for experts and registering. Which does not sound very sensible anymore.
Of course I could go with the B200K/S and change the head to 234f...

The body is basically the same, you can recognise a 360 from the trim depending on the year, but you have to be very erm , enthusiastic lol.

All 360s are red block and torque tube, gearboxes are similar between 200, 340, 360 but you need some specific 360 mating parts so you may as well take the full 360 drive as diffs vary with 5 speed gearboxes too.

Not sure if anyone mentioned but, the flywheel needs consideration for what ignition system you want use. 360 is a renix pattern, b230ft will be ezk. Using the ezk means you are reusing Volvo engineering so you need a fixed flywheel only available on some older big volovos, and not the dmf from the later 900s. The older 340 may have difficulty with the cam dizzy fitting against the ventilation on the b230ft, so you need 360/200/700 intermediate shaft dizzy, or the dizzyless mod for the ezk.

Hi, what about the late 340's which use renault engines? I got offer for 340, 1.4l engine with 52kw, produced on 1988. The 1988 would say it uses the 360 driveline parts...but as I am not specialist...? That combination is no use for me to transplant redblock into 343?

I've come to the point where my 740 wagon with B234f & 940 sedan with B230FB run well. Last summer the B234f got reworked and I am planning to use it for the 343. Until that I'll keep it running in 740. Spare B200FT will go into wifes 940, B230FB will become spare, good engine to use it in Lemons type of rally for example.

First phase is to get 343 running as is and get the body in order. As that is going, will pop B234f into it. When doing the power to weight calculations, it should become quite swell ride. Which brings me to another question. What options are there to get suspension up to date?
My current 740 wagon has BiIstein B6 shocks, lowering springs, upgraded sway bar in front and upgraded front brakes. I really like how that car handles, tail is quite loose but easy to handle, controllable. My point is that it is possible to get still good quality parts for 700/900 series off the shelf. How about 300 series, which options are there to get suspension up to date?

Thanks!
