But I agree it is a dying art and most under 20's likely do not know how to drive a manual.

The costs associated with a custom converter are exhorbitant. I've been down this path with local "specialists" who are in no way what I'd call a true specialist.

These days the stator can be cnc machined from billet and made perfectly, instead of splitting and rebrazing etc.

They also overcharge for what is delivered.

I have a list of 8 places, all of which deemed a rover converter (even a modded 4.6 one) to be too hard basket and I shelved any plans to use that transmission.

what you "can" do if you are suss on it, is rebuild your box with the 4hp24 internals and be mindful of the difference in the converters between the 4.6 and the 3.9

You will lose a little with the 4.6 and the 3.9 will possibly work just a fraction too hard, but - I'd still consider an r380/lt230 combo as the best of all, and even though I like the autobox itself, I'd skip it if I were in a rebuilding mood.

Your other option for an auto is a ZF8HP and a standalone controller, but you then have to mess with adapters and propshaft lengths and crossmembers etc... simply not worth the effort when the manual box is a proven effective and robust component.

Shifting is a privelege in todays world. laziness is the auto.

we all love to be lazy in city traffic.

use the L322 for that.

Once you start driving it you will know for sure. It depends how radical the camshaft is. It didn't sounds to have a crazy lope (valve overlap) happening in that video, so it might work really well with a standard torque converter. If the motor refuses to come onto song until 2500rpm .... it will drive you nuts with a tight converter though

I wonder if whoever built this motor ..... has ever built one that turns backwards

I have two grandkids, different genders, with manual learner's permits. They both complain about the difficulty finding manual cars to drive. Another grandson, on his red Ps, owns a manual 740 Volvo.

Jesus, they are as rare as rocking horse excrement. I've had a line of manual 140s and 240s but I never located a manual 740. Thought about converting mine, but sold it and bought a manual D3 instead.

the boss women here is making noises about needing a modern larger car (she has a little 2 door) now the middle child has taken access to her old 4 door car away (shifting out of home). I've looked high and low, the nice big 4 door saloon... comfy, grunty motor ... manual gearbox ... it just doens't exist.

I did spot a alfa romeo on fb marketplace from 2008 with a 3.2 litre v6 and manual gearbox yesterday. I MUST NOT go and look at it ... that likely would not end well

He and his dad converted it. Not as straightforward as it initially seemed. The CPS trigger is on the crank, which is as you described. Dad cobbled a trigger to operate from the front of the crank, but the vibrations limited revs. That wasn't a bad thing in the first couple of months of solo driving. They finally found the right flywheel in Sydney.

Ahh, yeah the trick there was having a mate with a mill and a rotary table to drill the side of the flywheel with the 60+2 pattern for the CPS. There's a couple of places on line that sell pre-modified flywheels for the LH 2.4 injection. The other problem is the 740 used a dual mass flywheel, so the best solution was to modify a 240 flywheel and conventional clutch.

I love my D3, but I miss my Volvos.

You'd get on well with my young bloke, his young bloke and Jerry's young bloke. They're all on some Volvo chat group.
