The year of the block and crankshaft don't matter really they will all work.
So here are a couple questions for you.
What is your budget?
What do you plan on using the engine for? Street/strip/something else?

Read it carefully
So this 1250 hp 5.3 is gonna run 4.80's@160 in a 3400 lbs car???
but show up with a STOCK 5.3, and make 1001hp@ the wheel with the converter the car is gonna run with....and I will gladly give you the $5000.00 cash!!

I am not saying it isn't do-able. But I wouldn't call it reliable either. 240sx 5.3 engine with trans comes out in 2 hours, car is made around the idea. But it still doesn't mean I want to deal with that **** every week.
guy asking about 650:
To go 500-800 most V8 swaps include either E85 or meth/water injection along with 60-80lb injectors, and as much head/cam/intake work as you can afford on top of the turbo. Trans/Rear to handle it and thats everything

Sorry for getting off track, Getting 650whp is either going to take boost of some sort or your going to have to spin the crap out of it. Neither option is going to be cheap and a lot is going to depend on how much of the work you can do yourself. Paying someone will eat your budget fast.

I have no issue doing the fab work myself. I don't have a budget set yet. The car is going to be a street car with the strip maybe once a year and an auto x once a year. I would like anywhere from 550-600rwhp..Do i need that much for the street no, but it feels good knowing its there

I'm running an LSA supercharged 6.0 with LS9 cam and TR6060 6spd, I haven't had it on the dyno but similar builds are around 500-550 to the wheels. Better cam and Ported heads plus pulley the supercharger would put it in the 600-650 range, Throw in a ported blower with the other mods and you could be at the 700+ rwhp range.
I'm happy with what I have, I have tons of low end torque and it pulls pretty hard until my self imposed 6,000rpm redline. I have to ease into in 1st and 2nd or it will break the tires loose and can't even think about using 100% throttle until I'm in 3rd gear and I'm running Nitto 325/30/19 tires. A turbo will get you more peak power and probably get you there cheaper. I have around $2600 in my brand new complete supercharger and factory accessory drive. I looked a couple days ago and prices have gone up considerably. Now to build the same thing would be closer to $3200 and that's with a used supercharger then add in the cost of injectors ( I bought ID850's $700) and a decent fuel system and you realize it takes a decent budget to get it done.

With your 6.0, did you use ls6 heads to match the LSA or did you use adapters? Also, what year 6.0 are you using? I was looking at running the stock cts-v crank pulley and running a 2.40 blower pulley to give me 15lbs of boost.

I choose to go with Holley EFI, Front drive accessory is a GM kit 19303242 - Modified LSA Accessory Drive System, w/o AC
Non-Sponsor Soliciting Policy
That kit requires a low mount a/c compressor that doesn't work with all chassis if you plan on running A/C

That looks nice. Unfortunately I will have to mount my A/C up high on the passenger side. If I try to keep my A/c down low I have to notch the front crossmember and I really don't want to do it.
Was there any specific reason for going with the Holley EFI versus stock?

At the time the Holley system was a little cheaper than it is now. I added the cost of a Harness/Computer/Wideband/added gauges and HPtuners software and I was within a few hundred dollars of the Holley system. The Holley system does so much more than the factory stuff can do but it's not really necessary, I like new toys so I bought it.

supercharger quick and easy
but it costs 100~ horsepower compared to turbo around 500-600rwhp
Show me 500rwhp supercharger car, that is a 600rwhp turbo car. the belt style rotating force absorbs what would have been rotational torque for the tires, that the engine had endure extra stress from axially applied pressure to the piston to produce. Important info if the bottom end has a limit related to piston stress.

Here is a comparison of roots and twin screw. Roots Red/ Twin Blue
There is actually a transducer used to measure the torque required to spin a supercharger or anything else that requires rotational force to function and twin screws are a lot more efficient than people realize.
No doubt a turbo will make more peak power if everything else is identical but we all know that never happens when you line up against someone elses car.
There are turbo cars making big power and also nitrous and cars with centrifugal/roots/twin screws. It all depends on what your personally preference is. For me a street vehicle with a manual trans and twin screw is my choice, My other build has a 6-71 roots on it and it will makes some decent power but also looks badass (to me anyway) I know I can make over a 1,000hp if I put a turbo on it but I'll settle for a big ole polished heat pump that I can barely see around that only makes 900hp because I think it's cool.

what do I look like, google? I have the same internet you do
1st random google

The hp consumption is the product of a number of things, the blower will consume less power at a given speed if it is operating at a lower boost level (pressure ratio), provided it isn't way off to the right of the compressor map (blower too small for the engine).

That said, a centrifugal blower blower typically consumes the equivalent of 15-20% of your flywheel hp at elevated boost levels. That is to say if you're making 1000hp at the flywheel, the blower input power approximately 150-200hp.
