You'll need $10-14K for the motor N/A, ERL no longer build engines btw, and another $5k in labor. I'd expect to spend around 20K (N/A) give or take
Garage is being built soon I'm doing all the work my self except machine work. Budget is around 15k I want a engine that is bullet proof ls7 isn't especially with boost
You can still get a Darton sleeved aluminum block from Steve at R.E.D. There's also the more expensive option of a RHS block. I spent around $7k for my ERL 454 for the bare shortblock. It's very easy to hit $13k to $15k depending on options. Another $4-5k for labor and yeah, $20k is a realistic cost estimate.
I recommend you contact an experienced LS7 engine builder. Tony @ Mamo Motorsports is located in SoCal, I highly recommend him. Ryne @ Cunningham Motorsports is another great shop. If you are serious about 1000rwhp out of an LS7 I would give the whole project over to a professional shop.
The pain of hotrodding on a sunday. The struggle is real....
1000rwhp on a c6z is a $35-40k job for the basics. $20k covers just the motor. Add the power adder, fuel system, drive train, etc. If you want it reliable and able to daily it, $50k+ easy.
It is actually cheaper/easier to buy one. There are plenty of 1000-1400rwhp vettes for sale for $55-65k. You can buy a complete car for less than what it would cost to build one.

I was thinking about selling the Bette and saving for a zr1 found many for 49-53k but it's to much of a hassle and the reason I got a c6 z06 over a stingray was cause of the engine mainly. But what my plan is cause i want the experience the learning process is to start off with the build as a NA motor that way I have 3-6 months to save for f1x pro charger etc other parts needed drivetrain is dead last. I'll worry about blowing **** up later lol. But my main point was just to have a 427 I wanna keep the originality no 454 0r 500. You guys don't think I can build a NA engine 427 for 10-15k then also have it later to upgrade to a super?

ERL isn't out of buisness. They just shut down the automotive engine branch to focus where the money is.....
My first choice for any LS engine building work would be Erik Koenig. Formally HKE, but now has a new venture called Horse Power Research.... I only just found out about this a few weeks ago. Just give Erik your budget and goals, and give him free reign. https://horsepower-research.com/coll...-engine-blocks

You can definitely build a stout 427 for $15k. But it won't be a barnburner. You can get a sleeved, forged bottom end for that kind of money but you'll be out of budget on fancy heads. You could put a blower cam in it now, stock intake manifold and throttle body, fix the valve guides, forge the bottom end with a good block for that money. It will be "strong" for that money, but this round of spending won't get you a ton of speed. It would be good for boost later on though, and plenty more dough.
A ZR1 is a better platform to start off with if you know you want big power.
Building a 15k n/a motor, then adding a SC is not a good plan. The motor will be built completely different for N/A or boost. So could you build a boost motor, and then save up the extra $20-30k for the FI part, sure. Probably better off to do it all at once.
Sell your car, buy a built car, be done is the best way.
5.3 block sleeved by R.E.D. as mentioned he is in So Cal.
Or one of the new Aluminum Blocks that C.B.M. sells, also
In So Cal, they also build a lot of FI LS Engines for off road
Racers.

Hmm maybe I'll go NA and do nitrous, but the guy at Texas speed gave me a quote so it's 12000$ shipped engine is put together and balanced a stroked ls to 427 dart sleeves I think he said Wiesco stuff and rods and all and prc heads everything for that price. All I need is valve cover, rocker arms intake/tb and accessories
I want to track the car also I think 1000whp will be insane to keep it on the track not drag, I'd like to do both actually. But when I do drag I want that extra HP should I get a engine built for 200 shot or maybe run high compression and add a super charger later and run minimum boost for 700-800hp
