You may be confused with the cam issues especially the oil pump drive gears shearing as the Cams do float forwards although there is a fix for this its reliability at load and revs is suspect.

As for the Slant 6 (225) they are reliable as hell even 50 years down the track, Aus never got the 170 slant BTW, only the 225 and they are a highly under rated engine.

We did get some 245 slants in Dodge trucks. They can be identified by an extra core plug on the manifold side, and by valve rotators if they still have them fitted. They are rare and if you can find one, grab it.

i hunted for more info on this years ago and came to a dead end, the 245 slant seems to be a myth, measured up a supposed 245 slant and was just a 225, id love to be proven wrong just haven't seen any proof to back up the theory, no one in the states seems to know about them either

i think the extra core plug determines an early and late block, what do you mean by valve adjusters? adjustable rockers?

Valve rotators, not adjusters. The device gradually rotates the valve whilst running. Cleans the crud off and helps maintain the seal in hard used engines like trucks. Hemis used in trucks had this feature also.

cool, just looked them up and i havent seen them before, are they not capable under high load or is there another reason we dont see them in performance builds

does anyone on here have an adaptor plate for a 245 hemi-series land rover gearbox?
got everything else lined up now but its kind of useless unless i can get an adaptor.

cheers

i know where there is one in wa, would be costly though by the time its removed/sent over

Talking Valiant/Dodge , I have a 56 model series one here with a 318 shoe horned in.:twisted:

One has to clarify that statement about series boxes quite a bit.

The SIII box internally is quite a bit different to the SIIa box. Most notably in the thickness of the 2nd mainshaft gear, which has been reduced to the width of the 1st gear. If you look at the image below and imagine a set of synchro cones squeezed in between you start to understand.

I must get an SIII cutaway image sometime.

The best box in the very late SIIa, which has the benefits of large layshaft bearings (Suff B ); shouldered layshaft (suff D) and sealed primary pinion (? suff H)

Ive been spitballing the idea of replacing my 3.5 rover V8 with a 3.5 lt (225 cube) Slanty and adding a set of long runner manifolds and a 4bbl.

My reasons for using the slant are that they are cheaper to repair, parts are still available from the US because of their continued use in the early 90's as marine engines, they dont suffer from cam walk or oil pump issues nor do the dizzys handgrenade unlike the 215/245/265.

A bit of head work and a fancy intake and they boof along nicely.

Id also leave it slanted.



Aussie Slant 6 had a bigger footprint for driveline hookups because of the predominant use of the 904 auto's which are basically a smaller torqueflite with the exception of the 245/265 "S" Block which was produced by Tonsley park in the 70's because Borg Warner went on strike for yonks and Chrysler got sick of being held to ransom.

So the S block allowed them to use imported 904 and 727 trannies behind their 6's.

My only worry with using a Hemi 6 in a landy/rangie would be over revving the buggers in low range because unlike Landy and rangie v8's and 4's who dont mind a rev the Hemi 6 gets a bit testy over 4500 rpm (Cam walk again).

So unless youve spent a bit on the donk to get her to rev cleanly and added a nice balancer I reckon a rev limiter might be a good idea.

Cheers,
Tony

Hey Tony,

Thanks for that, mate. Yep, I know that the Hemis were not truly hemispherical heads - I was just trying to work out what motor was being referred to.

I'm interested in your thoughts on using a 4BBL rather than a 2BBL on a slant in a Landy. I know there are four barrels and four barrels, but I would have thought a slant with a two barrel would be adequate to punt a Landy around and with less potential for becoming fiddly on tuning.

Is it right that the marinised slants up to the nineties were turbo-diesels? i heard that once, and have always hoped it was true.

Hey, and speaking of the "S" block, I remember hearing of Aussie Hemi sixes in Canadian Valiants fronting torqueflite boxes. Do you know if such a thing ever happened?

Cheers,

John

as far as i know, no hemi sixes went to canada.
nz was the only place that got them i think, but i cant remember what the japanese exports were, south africa got slants in everything
