swapping a 5.3 in my 01ss to replace my blown up ls1. looking to see how others with 5.3's are performing. looking to know

what yr 5.3:

i'll be using a 5.3 out of a 04 silverado
mods are ls6 intake/tb, long tube headers, 3200 stall, 4.10 gears, 175hp nitrous.
full street trim, rear seats and all. I have no clue what to expect @ the track when its all put together so if you folks would, post your times, mods, weight, year to help me get a general idea of what to expect

If it has a stock cam then I wouldn't expect any better than high 12 to low 13 on motor and low to mid 11 on the spray. You need to run a 28 in tire on the kit with those gears but I would highly recommend a swap to 3.23 or 3.42 gears if you are running a 10 bolt rear. Even if you have a 9in or 12 bolt rear I would say you need less gear with the 4l60E tranny.

3.42 would be better

it wont have a stock cam(23x/24x) and the heads will most likely have some pocket porting/bowl work done. Tires will be 275/60-15 drag radials.

i'd gladly trade the gears for a set of 3.73 or 3.55 gears

Well a cam that big in a 5.3 will be a dog down low. A cam like that needs at least 11:1 compression. It really needs 4.30 -4.56 gears with a 6 speed but you could get away with 3.73 in an auto car. You will need at least a 3800-4000 converter . I would make sure you have good PTV clearance with that cam. Something in the mid to high 220's duration @.050 would be much better. Good luck and remember bigger is not always better especially in a street car.

WELL my buddy that had the cam sold the cam and his car so i'm back to the drawing board as far as that's concerened. looking into a 228/232 or something of that nature now. and working out a deal with a buddy of mine on a set of 799 heads, roller rockers, and pushrods. hoping for mid-high 10's on nitrous @ the track and a solid 11.0 on the street

You should PM "sman" He swapped a 5.3 into his camaro to replace the V6. Was stock internal and then he put a 224 cam in it. Also has had a few converters.

I know he went to the track with pretty much every set up also.

Im also doing a n/a 5.3, stock heads, 85mm bbk ssi intake and tb, pacesetters, injectors, and a custom cam through a 6 speed with 4.10s. Looking into a custom cam specced by lloyd or ai. Waiting fot results on others as well! Mine will be done by the end of spring

Bone stock 5.3 I was running 13.8.

LS6 intake, pacesetters, 3600 converter, TR224 cam had me at 12.8 on street tires.

J$Money

well i'm a few parts away from having mine done and installed.

LS6 intake
227/224
LT headers
4.10 gears
3200 stall
175hp nitrous 1 stage
125hp(possible 2nd stage)
and heads ported/polished

should most def be fun on the kit and on motor

Awesome you should post a video when your done i really want to see how it is, and what your results are. It sounds like it should be pretty stout. I still have to replace my dash and lt1 body harness with a ls1 body harness. Im anxious to see what these will run. I plan on running a 150 wet shot.

J$Money

i plan on it, its going to be on a single stage for a lil bit to get it dialed it and to run a real street class around here but i'll be on 2 stages grudge racing. pm me some pics of yours or a link to your build thread, once i get my remaining parts i'm going to start my build thread with the install and 1st start

May want to rethink that cam with nitrous. You need more exhaust duration than intake especially with that much spray. In that range 224/230 or something with 6-8 degrees of split would work much better.

J$Money

the nitrous is a sub for forced induction for the time being. Car will be getting a supercharger when its all said and done.

Killer5.3

iTrader: (1)

Ok, but here is a link for you to look at. Forced induction needs a different cam design and even turbo is different than supercharger. Just trying to keep you from being disappointed with your results or pissing in the wind so to speak. Look at the camshafts in this link and you will see what I am talking about.

Sadly, no. There is about 8" of snow on the ground. currently building a set of studded ice racing tires for it now though. Yup, thats how we get down up here. Planning on cutting off the cats and doing duals dumped at the axle before I do go get some times.

Cool. I will make a build thread when im ready. I decided to just get my ls1 harness converted to plug in to the lt1 car. In trade with my lt1 harness amd pcm im only paying $50 to have it converted. Im currently looking for a t56 then ill be ready to start a thread. My builds almost the exact same as yours only with a bbk ssi intake and 85mm tb and a different cam and six speed. I will eventually be running an ebay gt45 turbo and ebay ptk copy style hot side kit once all the bugs are worked out n/a. I might even make a few passes before i start the turbo part to finish the build.
