engine and gearbox choice for hotrod truck

[Wendle]

I have a period correct 6-cyl flathead and non-syncro 4-speed you can have for cheap. It has 87 genuine, rated horsepower and will match your drum brakes perfectly.

Looks like a nice solid body to start with. Has it spent it's whole life inland?

I'll definately grab that motor off you when i turn 60 and i've got nowhere in particular to be in no particular time frame Mate the air con i intend fitting alone would probably use half it's horsepower

It definately looks pretty solid, and by the sounds of it it's been near Yass for a long time.

Does anyone know what i could sell an sick, but running 350 chev out of a 79 model chevy truck for? probably about the same vintage motor i guess, i don't know any more than that.

fit a td42 t out of a nissan with a caball 10sp gearbox have just done this to a 70model f350 very nice to drive

392 v 8 and allison auto out of a 1982 international fire truck. pick up a truck for $5500 with only 180000 ks from caboolture,qld.stick it on impco gas gear and get 5ks per litre on gas at approx 55 c per litre.shitloads of torque up to 4000 rpm.when they designed and tested these motors they ran them at full rpm for 1000 hours......smooth as.

if going down this path, i would definately be going for the 345 as the 392 is renown for doing heads, and because of this heads are becoming extremely rare, and therefore expensive.

Petrol hotrods are all over the place. Diesel hotrods are soo much better.

And soooo horrendously expensive But yes, i'd love to sit and smoke a set of dually rears while listening to the jimmy screaming it's farking lungs out.

I have finally managed to get a hold of the engineer nearest me and he's given me the go ahead for either build plan - either retain the original chassis and replace the driveline or replace the entire chassis. So now i have to make the decision which way to go.

Keep the chassis

Pro's

Keeping the original heart and soul of the vehicle (i.e. it's chassis and cab together)
Able to carry my cruiser round the country and not worry about getting it home somehow if i break it on the tracks.
Not having to somehow get rid of a chassis and driveline.

Con's

Probably use more fuel than a smaller C30 chassis
Need to build a much larger shed to store the damned thing in.
Higher rego and have to stop at weighbridges for inspections
Possibly higher build cost getting all the driveline, suspension and axles from a Hino etc.

Ditch the chassis for a C30

Pros

Probably be an easier beast to drive and handle better. Big brakes, IFS etc
Slightly lighter so probably less running costs and rego all else being equal
Probably slightly less to get the components for - i can get a runner C30 for 2 grand or so.
Probably more of a hot rod than a practical truck, hence a little bit more fun to drive

Cons

Obviously i'm a bit more limited to what i can carry. About 2 tonnes is the limit, so that means towing the devil on a trailer and the costs that incurs.


So i guess i have to work out if it's really that important to me to be able to carry the devil around or if i'm happy to just occasionally borrow a car trailer and tow it.

By the way, even the engineer thinks i should put a screamer in it

... stop at weighbridges for inspections

probably won't happen.
In the 9 + years I've had my '78 Terry, I have only ever been stopped once at a W/Bridge, and that was with a tarped load. I've pulled in several times, but they've waved me on soon as they see I only have either the ute or the lil'ole tractor on board.

One bloke explained to me that they simply not interested in anything so obviously lightly loaded. Got enough to do on big rigs without messing about with a slightly over-sized ute.

cool - good to know that. cheers mate

[pozman]

have you thought about re-cabbing an newer Isuzu or hino truck?

I've been thinking about it for a while now, old school track cab on new school chassis, know one would really know the difference, and would be more comfortable and reliable, not quiet as much charm as the old girl tho

I'm going to be doing a 1940ish k series international pick up this way, only a tonner tho

[Mrowka]

The old International motors were/are legendary in the 'States for being underpowered, overbuilt, and extremely stout units. Parts might be hard to come by.

Who made the 392's, how hard are they to get parts for and what size rad would it need to keep it cool?
got wood?

Inter made the 392's and a 345 V8.

[flyinwall]

there was a ford trader diesel for sale on ebay that would suit you as it was just a running chassis (chassis motor gearbox diff complete just minus the cab)

Thanks mate. I don't get into the ford v holden thing but i reckon i might get lynched if i did that.

How about the GM Detroit 6v53T, they have been used extensively for years by the US millatary in Tanks and personell carriers. I have 2 of them powering one of my boats, they are reliable and will happily run all day long. very low maintenance and very economical. theres a few vids on youtube. Only problems we get from them are minor oil leaks.

I had definately thought about it, but the detroits are supposedly not real happy about idling or low load conditions for any length of time, or they start dribbling oil everywhere and glaze up. At least that's what i've been told. Not only that but they're getting old in the tooth and finding a good block and head motor that's not rooted is getting expensive.

By christ the sound they make gives me wood though.

Just some chinese truck news: http://news.drive.com.au/drive/motor-ne ... 1ftie.html" onclick="window.open(this.href);return false;

Initially two trucks will be offered: 4.5-tonne and 8-tonne GVM units. Both are powered by the new Cummins ISF four-cylinder diesel displacing either 2.8 litres or 3.8 litres.

These engines are rated at 110kW/360Nm and 105kW/450Nm respectively and will be backed by the tried and proven Allison 2500 series five-speed full automatic transmission. Manual gearboxes will also be available. The inclusion of a US driveline is a first for a Chinese truck

I wonder how cheap they will be?

They will most likely be powered by chinese made cummins' made under licence by the chinese. We're using locally made cummins 6BT's over here now as gensets and the're not the same quality as an american delivered item.

Cummins parts and engines are made all over the globe. Including China. "American Delivered" does not mean "Made in America".

Ok, you know what i meant though. The quality of parts, materials and finish leaves a lot to be desired from the chinese made items

[KiwiBacon]

Rubbish. Cummins parts from China are to the same specs as cummins parts from the UK, US, India or Japan.

If you buy copied parts there's no guarantee.

you will find if you look closely at all the parts they all come from different parts of the world.

CAT 3516 engines for example
aluminium intake tubes made in the uk, heads cast in US, assembled in australia (sometimes) block cast in china (sometimes) exhaust manifold pieces cast in india... all large diesels are the cheapest parts from over the world and have quite tight tolerances.
CAT/perkins and cummins have a quite good QC and are more than fair (in my experience) with warranty. cummins do awsome motors compared to the magority of companies in the same field and in general have higher power to capacity ratios (CAT have now got their ass into gear and are producing some good motors but are still carnts with warranty)

[BIGDAVET86]

Cummin 6BT and allison auto. Pulled strait outta an acco. dead simple, parts easy, can be dolled up with parts from the states to make a fairly exciting amount of ponies... Or left as is and will drag what you got allover the country side.

I can certainly back milo up on this. Yes you are correct when it comes to chinese made parts that are exported but the chinese made gear that is used domestically in china definately isn't controlled nearly as much and is usually sub standard to the export equipment regardless of the brand name on the item.

OOh yeah, they sound great, bloody loud though, my boat had straight through pipes and you could hear it from miles away, the local residents near the marina complained to council about us firing it up at 5:30am, had to spend $2500 on the latest fibreglass wet exhaust mufflers to quieten it down a bit, they still have a nice sound, just a fair bit quieter now, they do dribble oil, and they do glaze up a bit when run at low revs for a while, we cruise at 1700rpm, but generally towards the end of the day we open them up to 2800rpm for a short burst to clear em out, they are an old motor, we spent $60k last year to have both of them fully rebuilt. in saying that though i expect to now get many years out of them.

Hey dave,

Any idea what years they made these until? From what i've found on the net, the best year 6BT's to get are up until mid 98 utilising the P series fuel pump. After that they went to Bosch rotary pumps which are a pile of crap and have a proven record of dieing if you don't maintain or lose adequate fuel pressure to them.

[KiwiBacon]

The US 6BT's used in dodges could have very different injection systems to anything pulled from an Acco truck.
