Default LS Swap

Wanting to swap my engine and trans, But undecided on what engine/trans and from what make and year. SC/MC or a LS Swap. a LS Swap really has my interest but don't know what engine and trans would work and bolt up. This will be my first swap looking for advice as well ideas.i have a 2000 MC/SS 3800 L36 6Gen

As mentioned in your other post, I don't think it's worth it to swap in an LS.

The only (relatively) easy option is the front wheel drive LS4 out of a newer monte ss / impala ss / gp gxp / etc. All other RWD LS engines would require extra work.

IMO a l67/l32 3800 is a better choice for a few reasons:
-Itll be a nearly plug and play change with your current harness since you already have a NA 3800.
-They're very cheap
-It can make far more power than you'll ever be able to use (between the trans limitations and traction limits). No doubt a built LS could make more power ultimately, but you'll never be able to hook and the thing will eat transmissions for breakfast
-bolt ons for an L67 gain more power since it's a boosted engine. There aren't a ton of cheap and easy bolt ons for the ls4.

I believe I want to go with a L67 engine and trans swap, for my first swap. I want to upgrade from what I already have. I believe stock a NA 3800 makes 200hp if I'm not mistaken and 225 in torque. SC 3800 makes 240hp and 280 torque. I think I came build on that with a few changes before I drop in back in. with the rite mods. I know more air means more horsepower. But you can get gains from the cam as well, and pulleys on SC. but that all I know .

Doing a cam swap with the engine out is the perfect time. It'll never be easier.

With that said, I wouldnt worry too much about doing a ton of mods for a couple reasons:
-it's easier to diagnose issues on a stock engine during a swap. If you did 20 things to it first and then swapped it in and it ran poorly, it can be harder to figure out what's wrong. Is an aftermarket part bad, is the cam installed wrong, is it a wiring issuex etc
-you also don't want to put so much money into it that you keep pushing the swap off. Do what you can in a reasonable time for your budget and worry about the rest later.

Keep your engine and but a used intercooled turbo kit. Will make way more power than a supercharged 3800 and be a lot easier to install.

Normally I'd agree, but if I remember right, he's got almost 250k miles on his powertrain. I think that's one of the cases where getting something lower mileage in would be worthwhile.

I would still use it until she goes. Then replace it with another l36 engine. They are cheaper
