Yours looks sweet! And yes, it can be done on the cheap.

To get to our LS HP and torque levels you'd have to shell out some serious $$$$ in an SBC or (heaven forbid) and Olds 307!

Just sayin.

the Olds 307 is probably one of my favorite engines.. but even in top tune a tired high mileage 4.8 would run circles around a good 5.0 Olds...

A little more cleanup and farting around and ill have the engine in soon enough.. :)

A friend of mine is an old-school small block Chevy guy. Before I got my LS he was trying to "virtual" build me a 383 stroker. Target was 400tq/400hp (which is what I have now). We stopped when I realized the bare AFR heads for SBC were more than my entire budget!

I love ls engines and would love to swap one into something old. However 400hp isn't really very expensive with an old carbed engine really. Buying an ls engine from a junkyard and swapping one in obviously saves a bunch of money. A 383 making 400hp and 400 torque could be easily achieved with 200 dollar junk yard vortecs. Of course your gonna spend 1500-2k on the bottom end though.
When in doubt, tach it out.

I've not been to the dyno yet, but I'm prob north of 400/400 at the crank.

As for the SBC, I didn't really want to have to wind a 383 to 6500 all the time. Plus machine shop work (block would need to be clearanced). And those 2 bolt mains would have me worried.

I was sick of seeing first gen belly buttons 20 years ago. That said you don't need AFRs or 6,500 to make 400/400 with a 383. But I do love the ls series. The 5.3 makes a great motor in a light car and the 6.2 is great in the 1/2 ton pickup or transplanted in a G.
In the muscle car era if it had a small block it was your moms car. When you turn your car on does she return the favor? Life's short enjoy your ride. Hybrid burns gas & rubber. Check out my photo album.

x2! That's what steered me towards the BOP stuff. I hate to admit it but LS engines are looking like the future of hot-rodding. On another note, my oldest son just got his learner's permit. I'm trying to get my kids into cars and I think a g-body with a 4.8 or 5.3 would be a good start.

I'm not knocking you guys with carb conversions, but one of the allures of the LS swap is fuel injection IMO. Cold weather start-up, drivability and decent mileage are a huge plus in my book. I had fun frying tires when I was younger and what-not, but now I want to be able to comfortably drive something across the country.

what other transmissions could you bolt to the 5.3? can you bolt a th350? 200r4? and still have it fit in a Gbody?

hey 1984 monte carlo ss you can get a tci kit that will mount all older transmissions to ls engine. You can even get kits for t-5 and super t-10s to mount to ls engine.

.Not a problem anytime. I to am planning a 5.3 swap with t-56 though. As far as I know you just have to swap to f-body accessories on it. I am still trying to figure out all the emissions stuff for utah. It doesn't matter what motor you have the car, you just have to run the emissions stuff that can on the car. Check out John B's ls7 he put in his monte ss http://www.montecarloss.com/ls1montecarloss/. Also here is the gbody swap thread on ls1tech.com Lots of good info here about ls swaps in our cars. http://ls1tech.com/forums/conversions-h ... hread.html

If you live in a strict smog area like I do, 5.3 swaps and carb LS swaps are out of the question since both are illegal in a G body under Fed law for the whole country, but it's only enforced in a few areas for now. 5.3s are truck engines and it is illegal to install a truck engine into a car or vise versa. Installing a carb on a LS disables the LS low emission systems, a big legal no no. While most areas may let you get away with these illegal setups for now, not every place will let you. So always check your local laws and the degree of enforcement in your area before buying anything. If I ever do an LSX swap, I would just get an E rod LS3 for ease of mind with any legal issues IMHO.
