Hi All. I came across a 350 for sale. The engine number is V0126DRK19C144705? I was told it came out of a 1970 Camaro? It is still running but will not come with pulleys, starter, extractors/headers etc. Comes with Carby, Manifold, Air Cleaner, Water Pump, High Volume Oil Pump, Flex Plate, Flywheel, Converter, Electronic Dizzy and Harmonic Balancer.
It is still in an old Morris Truck. Asking $3250? Is that a good price for it?
I was thinking of using it in my HG Van as I don't have the original engine anyway. The van is set up as 186 trimatic (on the column) so what box should I use with it to possibly marry up to the column?
Also a mate just picked up an aussie 4 speed (6 Cylinder) at the local markets........ It changes perfectly and came with the (bucket seat) shifter attached. How much is it worth? And how do you tell exactly what model it is from? He paid $80 bucks!!!!!!!!!!!!!!!! And it even had the clutch kit sitting on the input shaft! Been sitting in the old fella's shed for years.
I could go the other way and use it behind the 186 as I already have bucket seats and a half console. Can you still use the half console with the standard shifter as I am not sure exactly where the stick would come through the floor? I told him I would pay him double to cover the frieght.....
TIA. Ron

As above, 1979 LM1 auto. 350ci 4BBL out of a full size Chevrolet. 8.2:1 though not 8.5. It was 170hp but only 165hp in California. It was net hp though, so will be GM1 test (SAE net) complete with emissions strangled exhaust etc. Basically the same engine as a HQ except with lower compression probably by piston dish or combustion chamber or both. They had 6.27cc combustion chambers. Easily rebuilt with different heads and pistons to be the same spec as what is in a HT-HG 350 manual or if you leave the heads fit flat tops and it'll be like a HT-HG 350 auto in specs.

For the 350 in HG the best bet is a RH shift Trimatic. Will cost about $800 for a bellhousing to suit but everything else is cost savings. I'd use a 308 though, will be easier again than a 350. Just need a bigger diff and tailshaft.

The aussie 4spd is probably worth $100 max. Will probably need another $400 minimum to fix it, they are almost always shagged. Most of the $50 6cyl boxes I ever found at swap meets were M22 as well.

Thanks Mark and Byron. For a low compression engine it goes very well in a 1951 lc3 morris commercial truck. The engine is very clean and runs smooth. Has t350 behind it and a 9 inch out the back. It's on hilux suspension and brakes along with power steer. It drives and handles well. The motor will be out tomorrow and the new engine will be in and up and running by Wednesday.
I pick it up next weekend. It doesn't need a rebuild imho however I would probably do valve guide seals as well as gaskets. The Van will only be a comfortable cruiser, not a hi-powered show car anyway.
How do you tell the difference between M20 M22 etc? I've never had a Holden with an aussie 4 speed. All my past old Holdens have been grey and red 6ers with 3 speed manuals a few hydramatics, powerglides and trimatics thrown in and one VC Commodore.
I found a 3.08 banjo diff head in the dirt next door after a shed fire and clean up. It is totally stuffed. Could it be salvagable with new crown wheel and pinion, spider gears etc? It is missing the yoke too. I have a mate in NZ with a nos 3.08 crown wheel and pinion still in the box.....
Thanks.
Cheers.
Ron

If it’s a short output shaft TH350 the whole thing will fit in the HG using a HT-HG V8 Powerglide crossmember and HK-HG SBC engine mount adapters and engine mounts. You’ll also need a HK-HG SBC sump, pickup and dipstick. You’ll also need a speedo cable from a HK-HG V8 Powerglide and cut the hole in the firewall for.it. Make sure it’s the right TH350 and you use the right rear mount etc. I’d use some HK-HG 307 Ramshorns too. But your biggest challenge will be the column shift which won’t be easy to do, best bet would be to track down a late HZ TH350 crossover mech but good luck finding one. This is why I suggested a V8 Trimatic. Yes the bellhousing to suit the SBC will be expensive but you’ll pay much more for the sump, crossmember and Ramshorns etc. whereas you already have everything you need already. Just remember the Trimatic will move backwards 3/4” behind a SBC. Your gearbox crossmember slots should take that up though and the column shift setup will need a slight tweak

Forget a banjo behind a 350, waste of money. Use something else. Even left field options like an old Borg Warner out of an XW-XY or a wider Volvo diff.

Hi Ron, just to clarify, to me it sounds like you are just getting the engine. The Morris guy is keeping the box and diff? My question would be why is he selling the engine only if it is good?
Also your mate got a bargain for the Aussie 4 speed and shifter, because a good shifter is worth that much if not a lot more on its own. The box is likely shagged (unless you are an expert it is almost impossible to tell without a test drive) but is still good for a swap over for a reconditioned one.
Also although HK pans the banjo, if it is a 170hp 350, a banjo will handle that fine unless you are a die hard burnout adict (which I gather you are not)

It will destroy the banjo. It is 170hp SAE net. Which means about 265-270hp gross which is almost the same as a HQ 350. The torque of it will tear a banjo to shreds. A banjo was designed for a HK-HG sized car with a maximum of about 75hp SAE net with a lot less torque. They built a heavier duty nodular iron case for 253 and 307/308 to handle a few more hp but remember those engines had far less torque than a 350, and the mid sized cars fitted with 307/308/auto banjo were always single exhaust which robbed a lot of hp and torque, a HK 307 standard would be lucky to crack 100hp SAE net, a HT-HG 308 maybe 120hp. That L48/LM1 engine exceeded the torque figure in North America for both the Saginaw and 10 bolt in a mid sized vehicle like a HK to HQ. Cars fitted with it were fitted with a Muncie and 12 bolt rear end, which is why a HQ got a Muncie or TH400 behind it.

From some real world experience if you can contain the burnouts, drive the car like a normal driver the banjo will take it. If I'm wrong then what is lost? Replace it.

True. But to make it legal as in “self-Engineered” fitting an engine that was available in that Series you have to fit the uprated parts that the 350 powered vehicles had. Which technically means a Salisbury and bigger tailshaft and uni joints. Luckily most authorities and Engineers don’t also know about the stronger rear floor in a 350 powered HT-HG!

If you were to fit a banjo you’d have to at least fit a V8 one which is a stronger case and bigger yoke. Plus a custom tailshaft most likely. When the banjo eventually breaks most of that expense is wasted. If the 350 snots the tailshaft before the banjo (remember a 350 powered HT-HG uses 1-tonner unis at both ends) and causes a big accident you might end up in hot water.

If keeping the banjo a 308 and Trimatic is a far better option as that combination was a GMH valid option, but still needs a V8 banjo or at least a 2.78 or 3.08 6cyl one with a V8 yoke fitted

Thanks for all your input.
I won't be doing any burnouts..... Just cruising with a nice V8 burble out the back is good enough for me. That is if I go with the 350. If I can locate the rest of the parts required I will weigh up the costs involved and go from there.
Is the SBC Sump and oil pick-up on HK HT HG peculiar to HK HT HG only or is it also common in any other GM Vehicles?
The owner with the Morris is only uprating his Truck because he has the funds and wants a bit more out of it. I think he said he is putting a 'Vortex'? engine in. He already has the t350 and a Tru Trac 9 inch. He is not a burnout man either. And he is older than me.
There is another HG Van in town at the moment getting a panel and paint. I was told the owner was looking at dropping a 350 V8 or similar into it. I am not sure but the panel beater told me he thought it was an original V8 Van. I haven't seen it yet. I will catch up with the owner soon as he is looking at putting a rear seat in and I already have a rear seat in mine which is coming out. He can have all the stuff I take out and I might be able to get what he removes to mostly complete my cargo floor.
I know how long a banjo will last with a 350 up front. Not very long at all if you use the loud pedal more than once. The second time will tear it apart if the first doesn't.
Thanks.
Ron

Sump is unique to HK-HG. You can buy aftermarket ones though but they are about $500-600.

You won’t find a Salisbury cheap. But what does work with minimal work is a 68-69 Camaro 10 bolt which is the same diff with different axles and drums. They are very close in width but need the HK-HG spring mounts added and some adapter hand brake cables. It will change the stud pattern to HQ though but that is easily fixed by fitting HQ rotors and calipers to the front. Then running HQ-WB wheels.
