Did you read? He wants budget and light weight. Alloy 6.0 is LS2, L76, ect. not cheap
Alloy 5.3 (L33) is much more common and very capable of 400 whp NA with 10:1 cr
welcome to the forums 
and faster then rankins old cammed trans am :rofl
that was when i was stock ,thats why he aint worryin about that car so he dont lose again
Welcome!
:lol
stock auto vs cammed stick…
who would have thought the winner would be… :rofl
Put a carb’ed 350 in it with Vortec heads, cheap and better than any of that crap that you listed.
Fuck carburetors! I’d rather diag a no start on an EFI car for ten years than pump a carb while cranking it over to start. I hate, hate, hate, hate…hate…carburetors. They suck. Literally. A carburetor has jets that meter how much fuel is sucked into the engine, and being an internal combustion engine wants to run wide open naturally, it tends to suck too much fuel. Hence the reason EFI, or even mechanical set ups, deliver better fuel economy. They regulate how much fuel the run away machine takes. And then there’s things like instant tuning adjustments on EFI machines. Change altitude on your carbureted shit, and you need to dig out your pocket screwdriver and make some adjustments. All the while I’ll pass you with my MAF sensor. And cold starts? Ha!! It all changed for me when my father had carbureted junk that he had to nurse with his right foot to keep running for the first 35 seconds, and mom’s cars were EFI and you could lean in over the wheel and hit the key and run back inside where there’s heat. And tunability…I could go on and on. But the short of it is, mechanical, multi-part pieces of equipment just simply don’t cut it for TRUE performance.
And yeah, 6.0L’s cost wayyy too much. I have an iron (LQ4/LQ9) 6.0L that weighs 204 lbs…about 90 lbs heavier than it’s alloy counterpart. Reasons I’m selling it. I’m not saying where there’s an aluminum five-three for $875, but it exists. And it’s cheap. And 87 octane reliable.
But I need a '97-'98 Y-chassis fuel rail…only LS with a return line to accomodate my Third-Gen fuel system…anyone? lol
I’ll make a carb run better (in all aspects of performance, other than maybe cold start), than any late 80’s GM junk EFI, esp when it’s being adapted to anything other than a stock engine.
I dont see a lightly modded 305HO getting around a 13.7 Stock LS1 4L60E… 
Nice. Except cold starts. Great. Perhaps the single largest driveability gain from electronic injection. Yeah. Carbs seem like amazing idea. But you’re also limited to a central induction point (unless multi carbs are used) and relatively short runners. Thanks again long tubed TPI setup. Or spiral intakes, such as LS based engines. And EFI also uses these wonderful things called replaceable PROMs. People make chips for modded engines.
And who threw the 13.7 E.T. in there?
Jesus christ, I’m learning a lot here! John, you writing all of this down?
One question, what’s a replaceable PROM? My twin-turbo ZO6 Corvette (with dat dere fuel injection) has no such animal.
That was I. Thought I read something about a L98 car being as quick as a LS1… Just messin wit ya. I owned a couple of these barbaric vehicles. I had 3 different proms burned for my 91 GTA: 377, alloy vette heads, TPIS Cam, Holley Stealth Ram, Built 700R4, 150 shot… sadly never even filled the bottle. I think the best thing you can do with these engines as you probably already know is ditch the restrictive intake. I think a good single plain carb style intake with the injector bungs in it and a intake elbow would be a great. The new 24X system with the LSX PCM has great tuning potential as well. If I had my GTA now it would have been an entirely different setup.
that replaceable prom is a dinasor …we now have flash tunes
Yes, electronic control modules have changed. This is old shit were talking about. Sorry, I don’t have millions of dollars to pour into an LS7. If I had fourteen grand to buy an seven liter V8, I’d visit my local GM parts center and walk out with a big heavy box. I’m broke and I need to go…somewhat fast. Ha ha ha, TPI cars are slow, I get it. Competition is essential, otherwise we wouldn’t race, or build shit. So thank you for your participation.
And I thought about the elbow on the carb intake idea but I don’t need a hole in my hood. I don’t have a mullet. Or glasspacks hung from the floorboards, lol, but thanks. LS management would be ideal, but again, cost is an issue.
You can look into Megasquirt, convert to TPI or MFI. Cheap for a real time tuning.
he has a C5. Forged LS6
i have a old lt1
i have a T.B.I. 4.3
