Most performance bits would be ex US I think?

[Struggler]

A friend had one in a UC about 10 years ago. The valve cover, intake manifold and carby all hung out of the bonnet.

You can imagine how far they would protrude in a LC/J.

[wot179]

Longer and taller.
I cant imagine it would be cheaper or easier to fit.
I like the idea though.

Hemi six has been tried. Will try and dig up a pic...

EDIT:


Fits a lot neater than the Chev motors, but the gm sixes put out HUGE power, like really huge. And even though they aren't really 'popular' in America, the market in general over there is so massive that there's still a lot of shit availible for them.

why dont you think about a modern 195kw V6 economy plus power

[Mr Lc]

hey mate i was gona do it too my project the shell is now forsale i have regency approval to fit a 292ci, most parts are from usa just look on the us ebay site u can buy heaps for them i also have a performance book on them. heaps can be done to them they have the same rods and pistons as a small block chev so yeah lots of stuff to buy. You can buy completely rebuilt engines from the states for about 1k us dollars do a bit of research as it can be done just need to put a recess into the lip on the top of the firewall to clear and you would have to run thermos and no fan.Also the engine is basically a 202 on steroids as holden based the 202 design on the chev motor, they mention engines in the states in this book putting out over 500hp NA, the guy that wrote this book has a studebaker with a turbo 292 they were trying to aim for 1000hp, they used two small block alloy heads with a cylinder machined off each then welded together to form a six head.another thing is they run a turbo bolt pattern so you can run any of the turbo series autos.Ther is a couple of lc/lj toranas with these motors, i remember a salt race with a 292 running twin 4 barrel holleys, however dont expect it to corner fast due to the weight in the front but the power and torque they deliever would make an awesome street drag car and to the average eye it will stil look like a holden six, would leave a few people scratching ther heads.If your interested in the shell and papers, the book or any other info just pm me and ill sell them.i encourage you too stil try this conversion,jus do some research on us sites, i wish i had the time to finish my project. cheers anton.

Thanks for the reminder!

[Collo]

Isn't there a Chev v6? Can't remember the details (or where I saw it) but it was basically a 350 with two cylinders missing...

Would be something different.

yep thats the one there is another car that ive seen pics of too, was a street car.an underbonnet install is possible its all in measurements and engine mounts and the manifold and carby you run.

[Mr Lc]

i think the chev v6 is similar to the commodore v6 and can be bought new as a crate motor from the us. being gmh i think the holdens motors are basically smaller versions of the bigger us motors correct me if im wrong ??

[Mr Lc]

if the air cleaner sits out a bit you can just make a small scoop to cover it as long as the opening is on the back, then it can be passed had to do it with my dads big block monaro we thought about using the xr6 hump but then got a old german guy to make a steel one that matched the bonnet lines.It prob wont look as good as it will be obviously off to the side, to be honest i still think you would be able to get it all under the bonnet, but i cant be sure as i never got that far with my project, maybe you could use webbers.

[Heath]

If you're that scared of having a hole in the bonnet, make or modify an inlet manifold; for side-draught carbs, EFI, or even just a carb that will sit a little lower.

As long as the motor can fit underneath the bonnet, that's the main thing

[Struggler]

The UC I refer to had a Duggan head so that may have been the extra factor that pushed the valve cover through the bonnet but bear in mind a 292 has a conrod that is 6.760" long (not the same as any other Chev) so imagine how tall the block must be compared to a 202.

I will say it made a lot of torque and had a lot of problems keeping the flexplate and balancer connected to the crank.

[Mr Lc]

good little read here.

I've seen the hemi 265 bconversions into kingswoods & toranas.Looks pretty good when they paint them red & put on the 3300 stickers on the rocker cover.

245-265 hemi can be be done cheaply & go really well with basic mods.
