I looked at it hard at one time too, and came to the same conclusion. You will get more power, and cheaper, going the traditional Pontiac power route. So I did, and proved it.

To get comparable power from the LS costs money. And don't try to sell me 'you can grab a truck LS for $xxx and do it cheap'. Seen too many failures by those taking that route.

Many end up looking like this:

Show me a turn-key performance LS engine 'kit' that includes a harness and ECU, then add all the swap parts needed too, and add it up. Even doing most of it yourself, you will quickly see it adds up to way more.

A junkyard engine is just that, junk, if you want a professional performance engine/combo.

Most LS truck engines found it salvage yards are in salvage yards due to mileage or other damage rending the host vehicle uneconomical to return to service. Let me give an example: my ‘03 Silverado has the 4.3 Vortec in it. Just to procure a serviceable 4.8/5.3 iron block core and all of the associated mounts and accessories is more expensive than building a 4.3 Vortec with an 8 psi turbo system on it. Think about this: ‘03 Silverados came from the factory with 4.8/5.3 LS engines installed in them. I imagine the costs associated with replacing a Pontiac V-8 with a LS would be comparable to replacing a 4.3 Vortec( Gen 1 SBC based) with an LS.
