if you took this Olds Cutlass and added a 426 hemi, wouldn't that equal a sleeper?

yes it would. However I'd rather use a Olds 500 inch "rocket block" if memory seves, its a BB olds sold only over the counter for drag racing. olds 455 a good second choice, and way cheaper.

You used to be able to buy an aluminium block 426 from MOPAR.

Go with a 454 Chevy bored out to 502 - easily available as a brand-new-with-warranty crate motor from GM. Bolts right in with the correct engine mounts. FWIW - local guy somewhere has a box chevy caprice stripped and caged running 10s in the quarter with 454 and spray. outside looks --fairly-- stock

Hemis aren't that great when compared to modern engines of comparable size. They sure are a heck of a lot heavier. The heads are what they had going for them back in the 60s and 70s, but modern heads have caught up, and now it's just another big block, but heavier, and cooler.
The above represents the opinions of Tuna and only Tuna.

For the cost of a hemi you could instead put in a modern GM LS engine. You'd have as much or more horsepower, it would weigh a LOT less, and you'll have enough money left over to upgrade the chassis (which on that car will accept many Impala SS/9C1 components.)

And I would imagine that a junkyard LS1 would be considerably cheaper. True HEMIs are pricy.

+1 on not using a Hemi. Unless it was a case of having one laying around, in which case I'd sell it, as you could buy an LS1, all the parts you need for the swap, and a couple Miatas for what it'd sell for.

that brings to mind the question, why are the modern hemi motors not as popular for swaps as the gm LS-series? there have to be plenty of dead rams and magnums etc in the yards by now.

The LS engines were here first before the modern hemi came along, so the aftermarket's already ramped up with conversion kits and such. On top of that there are simply a lot more LS engines around so there's economy of scale. Finally, I'm not sure of this but I think the LS is probably just a better engine - I find it amazing they can make so much power, while at the same time still have good manners and get decent mileage.

Most of those have Buick 3.8s in them, so swap a Grand National drivetrain into it and be done.

Sure it'd fit, but again, you're talking about a rare (read: expensive) motor with a limited (read: expensive) aftermarket.
From the sounds of things you're a Mopar guy and stuck with a Chevy?

okay, the viper's expensive. how's about a 5.0 bored to 6.0 with edelbrock heads?

5.0 as in 5.0 Ford? They don't bore out that big, 5.7L is the most I've ever seen out of one. 351Ws can be taken out to a 7.0L, though.
Why Edelbrock, though? Trickflow heads are supposedly the best when it comes to making power.
Why not just build an SBC? It'll bolt in, be RIDICULOUS cheap, and make as much, if not more, power as anything you've mentioned. Especially if you do a 383 stroker.

The LS motor aftermarket is big. The gas mileage would be decent also. Lots of 5.3 truck motors out there.
If these came with Olds 350s' - the Olds 455 will bolt right in the same location.

Ok. I know old Hemi's are as powerful or as light as a LS1 and they are more expensive. But they are just so much cooler. If you have the money to get a Hemi I say do it.

I don't think so. I don't think they were available with a manual transmission either until the Challenger came along (I think even the trucks were all automatic, though I could be wrong). That probably hurts the swap enthusiasm a little, although I guess they were only introduced in 2005, so we should give them a little time.
Chrysler has sold a huge number of these engines though, so hopefully they'll start turning up in junkyards for cheap. (Car-part.com says ~$1800 and up for the car version of the 5.7L, $1200 and up for the truck version. I guess that is pretty cheap for a 4 year old, 350hp engine).

New Hemis have bastard electronics. Not like the ease of the LS swap. Hell, GM has made it so easy, its like they want you to put it into everything.
Hemis guys and electrons don't usually co-habitate.
