If anyone has a bad/junk Gen I V8 in any condition, I want it. I don't care whats wrong with it. As long as the block isn't cracked of course.

My brother races for Nissan Motorsports now, but used to run with the Chevy V8 crowd. He wants to build me a super V8 for the ls. I'm basically gonna just give him money and a motor. Then he's gonna rebuild it in an insane fashion. New pistons, cams, etc. Ceramic coat the headers, custom machining, the whole works.

Does he know that everything will have to be custom made? Like pistons and whatnot..

Yup-
Pistons/high compression (custom)
Re-ground Cam Shaft (custom)
Gasket set/fel pro
-Port and Polish head
Valve Job
• (oversized)
• (multi angle)
• Stiffer Springs(source)
Port And Polish - Intake manifold
Better throttle body
Fuel injectors(source)
Fuel pump/(source)
Alternator(source)
Headers/(custom)/ceramic coated
High flow cats
Exhaust(custom)
Coil Packs/ (mustang)
Custom Coil Cover(fiberglass)
Hone the block(cylinder sleeves)
Powder Coat Block (Red)
Flywheel/Pressure plate(Not Sure Yet)
Chrome Plate Valve Covers
That's the short list. I need to source a cheap motor first.
So......who's got a bad motor???

All of this plus 1000s of dollars for maybe 50-75 hp?
Too much for me.. I would rather throw a supercharger at it IMO.. It would be one of a kind though.. Which would make it awesome

I have two of them. one has a spun bearing(s) and the other i'm not sure yet. starter is good but it just kinda "tings" when it engages the flywheel and i can see it trying to turn from underneath so i'm leaning towards a seized up engine. but you can take your pick.
PS
FASTLLS i picked up another ls sport just like mine that i'm parting out if you still need an SST shifter.

Those mods would make it a "REALLY awesome" motor and more than 75hp.
Ceramic coating custom headers alone is prob around 15. Plus exhaust, port and polish, high compresion pistons, etc.....If you really think about it you'll see what I am sayin and the engine will be sweeter. Plus if I can find the project motor for next to free which I may just have, than the final product will be no more expesive than a remanufactured factory spec engine putting out the OEM hp and giving 0 benifits other than being a fresh engine. With the peeps I have, I can have this bad boy up and running far better than any other LS non-super/turbo on the planet. (Theory!) And still have my original stock motor for a secondary rebuild project. (supercharger). I plan on never ever ever ever ever selling my LS, even if I have to push it to sweep around it! I don't owe a penny on it, so, this will be like putting a brand new engine, a better brand new engine in it. And, it will have all new suspension, rebuilt tranny, and many custom body mods. I may one day be the last person on LVC drivin a LS, but I will still be drivin it.
Sorry, alot of red wine passin through the system tonite!

dude if this were 6 months ago i had a gen 1 with a spun bearing....trashed it

Quik said that a port and polish gave him little gain. He said he maybe gained 3 hp out of the deal. He said they matched them pretty good from the factory. I mean it's your money and I'm not going to say that your not going to gain anything because you are but the LS has pretty high compression as it is. Just sayin..
Like I said, it will be one of a kind so who cares about power..

True enough. I think that with that, and a custom manifold, bigger throttle body, custom injectors, mustang coils, ceramic coated headers, custom pistons, better spark plug, higher volume fuel pump, better engine bay cooling,etc...
It's taking all the little things that have been tried and gotten little gains, and adding them all together with a pro tune and seeing them work in unison ...that'll be where the magic is. Guys have been known to get 5+ HP just on a better fuel tune. It's adding all the 5-10's together, and having them work together.

Okay, motor fell through, so still looking for a junk motor. Anybody out there has one, please let me know. Parts are starting to build up in the garage!

Modifications
Don't want to rain on your parade, but here's a few thoughts:
An internal combustion engine is well-thought-of as a big air pump. It's over-simplified, but if you can get it to flow 10% more air, it'll make 10% more power. But the approach you specified above---linearly adding the results of your modifications---is not a good way to calculate. It's like the guy who made a series of modifications to increase gas mileage. First thing you know, he was having to stop every little while and partially drain the gas tank to keep it from overflowing. NOT!!
Your list of improvements will likely produce as much as fifty horsepower. And require 116 race gas to run properly. A fabricated intake manifold will be horrendously expensive if you have to pay for it, and will likely be of little value unless you increase displacement to make use of the extra potential flow. It's likely that you'll have to make several iterations as you test with a flowbench to find improvements.
There seems to be room in the AJ block to increase displacement by about 25%. That suggests, being generous, that the upper limit of your projected effort will still be somewhat less than 400 horsepower.
You'd very likely be better off to spend your time and money going for a 'power-adder' or a combination of power adders.
Good luck!

Just for comparison, I was going to get a intake like Quik's one off CNC'd.. The cost you may ask.. 2-3k..
So I took a different route.. The CNCing wouldn't have helped much on the flow anyways and that's a lot of money to spend

I still have mine. It has a broke timing chain. Happened as I was starting it a few months ago. PM me with a # if your interested. Btw its still in the car.

1.Currently I have 110,000 miles on the motor. To SC ot TC this motor would be a waist.
2.What I am doing is building a super solid motor from the ground up. With the resources at my disposal, this will cost less than a fully reman'd stock engine, and would be way better than a new stock engine.
3. The intake manifold would be cast, and not CNC'd. And I am getting it done for less than $800.
4. Even if the engine gave exactly the same horse power, exactly the same, it will still be a practically new motor that I will know for a fact will be able to handle anything else I through at it.
5. The thing is also being built pretty. Red, Black, chrome, full dress up. Hoses, wires, etc. In the end I will be spending less than most guys have on this forum for swaping new stock motors in their rides that they end up having all the same old problems with. This may take a year or two to complete, and by that time I will most certainly be read to pull the current motor out.
As an added bonus, I am having every single part made twice. So I can rebuild the one in my car now and sell it afterwards.
Lastly, I will in the end most likely supercharge the motor. It wasn't the original plan, but it's gonna be the end result I am sure as my brother is already giving me sh!t about it.
So, we'll see what happens. The brakes, and suspension are done, so time to go fast or dye tryin.

The only supercharger I have seen was three times the amount I'm spending. The one Quik has is like $6000 isn't it. When I go SC,(when or if) I am just buyin the supercharger itself and havin the rest put in custom by my peeps.

A casting for that price? Are you sure that includes the design? Or do you have someone on the inside..
Why spend so much on an intake and then supercharge it.. Requiring a whole new one?
FASTLLS
Dedicated LVC Member
That's what I'm doing.. Projected cost is 1.7-2.5k.. Depends on the tuner.. Also, running water/air which costs a boat ton more..
lsdarkshadow
Dedicated LVC Member
Yes, a man on the inside. I cant say where until it's done, but you'll recognize the name when I get it.
As far as the answer to the why? Because I could easily sell it again on eBay for that price since I doubt anyone else can find one cheaper. There will be a year in-between the first build, and the supercharger.
