The only thing you would really have to do is drill & tap for the Alternator Bolt, everything else will be a direct fit & plug-in..depending on what 5.3l Engine it is..GEN III will go right in, just need to drill & tap still.

If you want to get technical you will have to change out the front Coil Springs for the LT1 spec ones if it's an Ironblock.

was going to do it but found a 100K LS1 for 600, and it was old lady driven, very clean inside dealer maintained, may not be a good thing, or,

Yes, that is what the 5.3 would go in.


Trying to put together a sheet to figure out costs.

Really sucks that the LT1 T56 is different than the LS1 T56.

bumping this one back up.

Any 5.3 FAQ's or anything?

Trying to find out exactly what I am going to need for this.

If I cam this little motor do I have to put rockers, pushrods, etc? Or just a cam?

For the LT1 car you'll need things like a wire harness, coils, computer, K-member, that kind of stuff.

I've currently got some of that stuff for sale if anyone needs it.

I've done the swap, but my car was orig. an LS so it was literally bolt on stuff aside from drilling and tapping a hole for the Alt. To swap it into an LT car you'd need a wiring harness, k member, new fuel lines or get alum rails and put inlet on one side and return on the other along with a new input shaft, slave and bell housing. I'm not sure if the Master Cylinder is the same as a LS car.

Super chevy did a build up on a 5.3 not long ago, its called Modern Mouse I believe. With just heads, cam and intake it put down some really good numbers IMO.

If your just doing a small cam then I'd just do rod bolts, valve springs and new pushrods, maybe new lifters and lifter trays while your in there just for the hell of it.

5.3's are the same as the LS1, the only thing like it was said above is that you'll have to drill and tap for the alternator bracket.

Here's a 5.3 I Installed in a customer's car although it was an LS1 car to begin with...

did you have to swap the balancer from the ls1 to the 5.3?

You have to use the LS1 accesories so you have to take the 5.3 off and put the LS1 on.
