Kingbird97

Hey, I'm currently driving around in a 350 lt1 in a 97 firebird. It's a stock block running on 62 thousand miles, require guidance and a parts list. Also don't treat this thread as a pure motor question, I also need help with finding a auto trans and a rear end capable of using and handling the high horsepower. The project will take me a while and allot of money, we'll pretend my budget on the motor is 10 grand. I'm new to this game so thank you

600whp in an LT1 through an auto trans is not a reasonable goal.
Spending 10k on an LT1 is just pouring money down the drain to begin with.

Being that you joined an LS based forum, I doubt there is a single person here that will tell you to build that LT1 instead of just doing an LS swap.

I just seen the 'running on premium' part. Either you joined just to troll, or you have no idea what you're doing.

Dumping 10 grand in any motor is pouring money down the drain regardless of platform.

If you're expecting any kind of return on an investment modifying cars is a **** poor choice.

I'll be the guy who plays devil's advocate.

Rotating assembly:

But you'd have more luck getting to 600hp with a .060 overbore instead of .030, at the cost of the block should you ever need to rebuild.

You'll need another $1.5k or so for CNC work and valvetrain

Another $400 for the cam, which you should get custom spec'd

I would advise looking for an Edelbrock intake ($500) and getting it worked over($500)

And the injectors/spark/other odds and ends will probably run you up another $1.5k

Good luck finding someone to tune an OBDII LTx, and now you will need a huge(>3600) stall, along with 3.73s at the minimum. Because you now regret doing this to your car, you can use that left over 2k to buy yourself a nice cheap beater for a daily.

OR, you can get a LQ4, cam it, swap that in, and have a nice and cushy 400-425rwhp and 6k left over to put into your trans, s60, and the tires you'll be needing.

Almost forgot, you will be lucky if you see that magical 600 number anywhere below 6500 rpm. And anywhere before 5k, you're gonna get eaten alive by the guy with a 503 and ported heads cranking out 350 whp.

even with forced induction if you could get there youll probably split the block
does it have to be an LT? Have to deal with emissions?

On radical builds throw the low compression/pump thing out the window it just never works right

OP

one way to do it......$10k will not get you there nor will you get there NA at 600 "RWHP"

This guys sig from another forum...

Looks like Injuneer's setup. If I recall properly, he said it made 500hp NA. The motor was built specifically to handle that 300 shot of N2O.

Where are you getting the idea that an LT1 block won't handle 600hp? I'm making 502rwhp NA. Sometime soon, it'll be getting at least a 150 shot.

^^^He usually gives out pretty good advice on the forum. Especially on the forced induction side of things.

But like myltwon said, dumping $10k into any motor is a waste of money. Thats just the nature of the hobby. But the LS platform only really offers LS7s and other big cubic inch motors that is capable of making 600whp NA, which in turn is way more than $10k to begin with......

At the end of the day, making a 600whp NA LT1 is just not feasible idea. Can it be done? I think so, but you'll be well over $15k and have to have a strong T56 behind it to get those numbers. Your better off going BBC if numbers are what your after......

The internet kills me sometimes. There are turbo, blown and nitrous LT1's well over 1000whp these days

cuisinartvette

See for yourself. May do it for awhile not very long
I only go by what Ive done not what the internet says

Op isnt going to make that number period on an sbc NA it takes a lot to get 500 to the tire more than most think

BALLSS

yes it's Injuneers sig/car. Clearly his build goes well beyond the motor itself....and $10k....but does make huge power

Eh, depends on how you look at it. The money I've put into mine has been worth every penny, whether it's simply driving or racing. What gives me peace of mind is I accepted early on I never wanted to compete with the ***** of the walk. Saw and read way too many instances of those with big dreams and shallow pockets and they end up scrapping everything. I've always wanted to simply be faster than stock and keep it as simple as possible. Still expensive, but well worth it. Doing an LS swap can get crazy expensive as well. All the little **** adds up. Still something I may want to explore before I'm too old to work on my heap.

SwampWS6

I agree. Every penny that I have spent has been worth it too. But at the end of the day, this is just an expensive hobby and one will never will never be successful in recouping the money and man hours that were spent. Only very few have been successful at that. So unless you build engines for a living or work for some type of racing team its all a waste. I just so happen to like to waste my money this way....

You mustve done something wrong then. You must not be that current in the LT1 community. At least 5 of these 1000whp+ cars are still living. So they must know the formula that you seemed to have missed. I was pass the 550whp mark even with having issues on gate pressure. So I do not understand your stance here.....

cuisinartvette

yup...not like these dont get torn apart modded rebuilt anyway noone expects them to go 100k
