Thread: straight six horse power

Tweet

The thing about slant sixes Drg84 is you have to take care of them better than a straight six. i had a friend that his slant caught fire. we pulled the engine with a 66 impala and a logging chain over a tree branch. after we got it out and rebuilt it gave us hell trying to get it back in it was a bitch trying to get the tranny lined up.

Ive heard off an Australian variant version of the slant six that has a hemi head. Now that would be the ultimate in alternative engines in a rod, a hemi slant six. I know the Australian versions have several different displacement sizes but maybe it wouldnt be too hard to adapt the head to an American block.

I'll look into it, make a few calls, talk to some people etc.

From memory the drunken rambling of my mopar mad flatmate a few years back, the Oz 6's were 225, 245 and 265ci.

The 265 triple carb motor in the Charger (sorta like a Chrysler hardtop but in short wheelbase) was a full-on V8 killer.

Now just imagine hanging a hairdryer or 2 off the side of one of them and watching your knuckles turn white. Lovely. And thats coming from me.....and I own 2 Fords.

Its all about passion I suppose (and going fast)

OK, the slant six in mine had 70K oldllady miles on it. Still diddnt want to play. Got Bosh plugs, new coil, rebuilt the carb, Compression testing, various timing combos, still wouldnt play. Got rid of it, and the guy who bought it had it stolen! So, maybe it was a fluke, but I havent met a good S6 yet. However, the HEI idea on the 4.2? Hmmm, potential. Also, another good idea for those in the AMC division. Take that POS electric carburetor and throw it, get a manual off an older AMC with an I6, Drive it about 200 miles, then set it all up. In my experiance, its worth about a 15% gain!

I saw a dodge dart with a slant 6 in it and with a few modifications to it it was blowing the doors off of some of the other cars on the track. the good thing about a slant is you can wind them up really tight.

Aussie Slant Six Hemi

Well this would be a great mill for an odd rod. The article I found wasa sales brochure for the 1967 valiant. It came in either 225ci or 245ci. I cant find any info on the 245 but it says the 225 was 160hp and only had 8.4:1 compression with a single two barrel. Id love to know if you can adapt the Ausstralian hemi head to an American block.

That motor is awesome, I just wish I knew if the head could be adapted to an American block. It looks just like our slant exept that its sitting upright.

According to the Mopar familiar flatmate from way back. All the Aussie 245 and 265 had Hemi heads from models VF to VJ. He's had about half a doz of them over the years and was pretty sure it was only the old 215 or 225 that didn't have it.
