Yes to the 10 speed and jake brake!

It's all in the gearing. They'll rev to 2500 rpm so the right gears it'll do better than 110 mph.

@@jerrykinnin7941 Ours was stock and only saw a road trip once a year. 70 MPH was pushing it.

yeah but you need to change the gearing. That is why their unit only does 60mph

the gears are helical. the noise comes from the straight blower rotors. 2 stroke detroits are not super charged. they are naturally asperated. if you need boost, you add a turbo.

@@georgedemas7718 All Detroit Roots Blowers have slightly helical rotors.

Thanks mate. Shes off to a new home now.

@@calhumps what was she worth?

I'd sooner attack the rear end ratio than go with twin transmissions. My 85 F150 came factory with a wide ratio 4-speed and 2.49 rear gears; 75mph is only about 1700RPM and the gearing in it would probably be better suited to a 4-53 Detroit than it is to the 300cid gas I6 it actually has! Good as the 300 is, a 4-53 or 6v53 would out-torque it too, so the thing'd probably accelerate a bit faster too lol. The upper limit of what these old trucks can tow was never their engine anyway. It was the brakes, the steering. I have pulled >7000 pounds with my 85 in the past; clutch was not liking life very much but otherwise it did it. Only rated 5500. With a detroit 2-stroke in the nose I'd be able to pull whatever I wanted to without issue. Still be limited by suspension, tires, brakes. Maybe that's what I'll do with my 95. Detroit 2-stroke swap it. That one has the same 300 I6, but instead of a wide ratio 4spd and 2.49 diff gears, it's got the ZF 5-speed and 3.08s out back.

@@TestECull sounds to me like your 85 has the perfect gear ratios a guy could ask for. This inline 6 300s were a fantastic engine really, though I prefer diesel- old ones anyway.. especially Detroits. The perfect engine swap would probably be something like a Mitsubishi engine I've got in a generator. 6D31-T. 302 cubic inch 117hp @ 1800 rpm with turbo. Quiet and very good on fuel. For me, the sweet spot is enough power and least fuel burned. As for your beginning saying rear end ratios over 2nd transmission. Yes. Except for money & options. I did my Detroit swap in 1991 before internet & had no money, but had donor truck parts.

@@lovesloudcars Mmhmm. Well that 300 is known as a diesel-with-spark-plugs to many anyway. Has about the same powerband as one of these 53-series 2-strokes, just not the earthshattering raw torque. But ye I think a 2.49 or 2.73 rear end with one of these baby Jimmies and a 4-speed or 5-speed manual would make for a vehicle that's quite comfortable on the interstate. 1700rpm is a pretty comfy spot for one of these Detroit 2-strokes to sit at for cruise when put in a pickup, yanno?

Vibrations not too bad. Noise, well yes. Probably best to wear ear protection for long trips...

And decent amount of torque but from memory dont think the engine revs that high.

@@calhumps that's a cool conversion 👌 Not sure I'd do it but I'm glad you did haha. You pretty much need heading protection in a 40 series of you travel over 80km/h anyway. Nice work 👍

Heaps of torque. Never went on a dyno

Nah sold it a few years ago. Very noisey on road and was full noise at 100kmph

No sorry. Not in our ownership anymore

Nah nelson airport

Original gear box, but it is a later 40 series 4 speed, not the 3 speed the 1973 model came out with.

Towing was fine i believe, yes it needed over drive, 100km/h was max speed

Was already in there when we got it. The 353 isnt very long being only 3 cylinder so it seems to fit in easily length wise. The exhaust was a bit of a pain as we had to re-do that, as last owner had a home made manifold which had poor flow.

Ok thanks I was looking at doing something like that

Nah

Yes

Fuck oath

@@calhumps give the world hell coz the world gives you hell :D

Donno, just smiles per miles really.
