I am finally getting some work done on the vega wagon and am getting near time to figure the engine out. I was going to run a 4.8 with an ls1 intake but I have bought myself an aluminum 5.3 and don't want to mess with the injection right now. It is an 08 model with flat top pistons and 799 heads. I will be deleting all the DOD stuff and building headers to fit the car.

My plan right now is to mill the heads .030" and run a tsp torquer v2 with 110 LSA cam with a 3600 stall. I am thinking of running a victor jr. intake but don't have a clue on the carb? The car will weigh around 2700# and run a 200-4r with 3.73 rear gear.

Is this combo going to work or do I need to change some things up to make it work? I am new to these engines and certainly don't know anything about a carb on one. My goal is to have the car running the 11's and then maybe put a little shot of nitrous on it later on.

Thank you all for your help and hopefully this thing will come together soon.

Sounds like 11s all day long to me.

We did a stock, and i mean stock GEN III 5.3 long block, no cam, in a 89 mustang, carbed and headers, went 7.9 all motor in the 1/8th, this was a full interior car with a roll cage, it was on a trans brake, but you can imagine your lighter car with a higher compression motor and a cam, it should be in the 11s with no issue as long as everything is tuned and dialed in.

The motor should b @ or around 400 hp and in a 2700lbs car 11's should b no problem !

There is nothing special about carbing an LS motor. Whatever you did with a first gen will work.

I would think a 750 with mechanical secondaries. Pretty much everyone with a 5.7L and larger run at least a 750. With your mods that should work for you too.

Classic double pumpers on an LS open pleunum intake tend to have a bog off idle. Not a big deal, just takes some tweaking to get rid of it. However a lot of members say Holley HP carbs work perfectly right out of the box. New ones seem to be a bit cheaper too.

Thank you everyone for the help. Since it seems to be the consensus it will run in the 11's, I will definitely go this route. I will probly go with the Holley HP 750 carb if that sounds like a choice. That is what I was thinking before, I just didn't know if it would work with this combo. Hopefully this will all come together pretty soon. I guess I should finish the car first though.
Thanks again

Nice find on an aluminum 5.3!!!! Where did you come across that? If you don't mind me asking.

Carbed LSx is a breeze. Just get an MSD box to run to your ignition system (24x or 58x), slap a carb on it, and go!

It should do 11s all day day fairly easy with that kind of power to weight.

I got lucky. A friend of mines nephew rebuilds wrecks (mostly GM trucks) and had this laying around. It has 6x,xxx miles on it.
