was wondering if people that have done ls1 swaps in their thirdgens can chime in and help. im wanting to do a ls1 swap and want to see what eveyone went thru during their swap and if i should even attempt an ls1 swap or if a fuel injected motor is just as powerful, reliable, and drivable. also any good ls1 swap threads would help to. also was it all 01-02 f-bodys or just a few that recieved the ls6 heads. thanks.

From what I've heard, the LS1 swap can be done as cheaply as any good SBC build. If you find a donor car, with low miles, engine/tranny/ecm/harness intact; would be even cheaper than some SBC builds. The power potential and aftermarket for the LS1 is very impressive, but so is the SBC. That's unfortunately all I really know.

I think you're better off finding a 6.0 out of a truck than an LS1 specifically. There's a chance it'd be cheaper because people think the truck motors aren't as good. 345hp out of the box!

If you can't do wiring it just means you're going to pay someone else to do it for you. There are quite a few places out there that will do a plugin play harness for your (speartech, etc).

The initial cost is quite a bit more to get an LSx motor in your car but there is a ton of potential. The LSx is going to be more reliable than a genI SBC.

Couple of threads....

Truck motor is the same dimension, sans the intake, but you'll want an LSx intake anyway. And everyone knows iron is more reliable than aluminumiumum. Razz

The truck motors take a bit more work because you have to car intake, car oil pan and car accessories unless you want to run a crazy cowl hood to fit the intake and a special spacers/adapters to fit the truck accessories.

The iron motors weigh about 80lbs more than the aluminum versions which is still lighter than your typical SBC because of the plastic intake and aluminum heads.

If you drop it in without a rebuild your probably going to find the truck motors were more beat on.

If you're wanting to use A/C and such you'll have to decide whether you want to use the 4thgen/truck compressor and notch the kmember/buy a tubular kmember and run custom made AC lines or use the thirdgen compressor on a custom bracket.

It's all the little things that add up. Very Happy

Don't forget fuel system, gauges, transmission, etc.

I have a carbed 383 and its perfectly driveable. Even with my huge cam. But 383's sure like to suck the gas, thats the only thing I don't like about mine. But I have been daily driving it to highschool since school started this year. Except for downtime due to the transmission problems.
