Yes, but as I said they were all autos. Manual 350 was basically dead by the release of Sandman. I think there may have been a few manual XW8's built early in 1974 but to all intents and purposes the 350 manual was no more in 1974. Even if the 400 wasn't pulled from HJ late in 1973 I doubt there'd have been a manual version either, and I also doubt they'd have been available on a HJ commercial. The new higher performance 308 released for HJ basically made the 350 obsolete too, as it went just as hard - a 308 manual HJ is all but identical performance wise to a 350 manual HQ. To put it into perspective, have a look at the 0-100 and 1/4 mile times as tested by Wheels or Motor on the early LX SLR5000 or SS 5 litre. They are as quick or quicker than the L34's tested 18 months earlier. These used the same engine as a HJ. I know the later LH's had the same engine but it is harder to find tests on later cars, most are on the earlier 1974 with the HQ spec 308 engines, plus LX didn't have a pea shooter exhaust!
