I would either build a LS1 427 with the AFR 225 CNC ported LS1 heads or a 434 with CNC ported AFR 227 CNC ported heads.

Lingenfelter builds a twin turbo 427 for their Vettes. I dont totally know what other turbo type setups they do but having seen their actually billing sheet I can tell you they are $$$. The engine and twin turbo setup alone costs $50,000 . . . almost as much as the dang Vette itself.

Lingenfelter.com is their website.

Galebanks.com also has a new turbo setup.

I'll take a 700hp, twin turbo Denali. Thanks!

$45K for the truck and another $60K for the motor sounds pretty resonable to me.....

btw this will not help me they sell mostly for corvette & hummer
as i see, and yes price seem hi a bit ...

What kind of turbo (low profile) i can use on SBC ?
Is vortec can be a good choice ?

I know almost nothing in turbo engine..
I know i need a 8/1 8.5/1 but not very mutch more..

I am just curious, do you have the money to do this right now? If so, I would be nice to know how much you are planning to spend. As was stated before, the lingenfelter combonations are around $50,000. If you have that much to spend, you can get considerably more than the 800-900 hp that they are making. If you dont have that much, there are different parts to consider.

I have less than 10k in my EFI turbo engine.....much less. Either of the above could get the job done, and Kenny Duttwieler could as well. Something tells me you can afford it, though. But, hey, if you can send us some pictures.

I have around 10k to spend, may be a bit more, not so mutch, lingenfelter too costly for me

...

But dont known where to start,

I just take a look at vortech supercharger that look
to be a good option, but i realy need to find more info
before buying someting...

I know how to build a powerfull non-supercharged engine, but i dont known a lot in turbo/supercharge ..

My wish would be a 434 sbc 8/1 ratio
A vortech supercharger whit a 150HP nitrous
may be whit it should make pretty good power.

i've known they were coming since last year because a friend of mine works with mobile homes and i just saw the first ad for their twin turbo kits for sbc from Banks. i also read tho, that they are small units. they might be small, but they sho aint gonna be cheap! but they outta be alot less than lingenfelters. have you thought about putting 8 turbos on it?

I think for $10,000, you may have trouble building a 434 with a turbo. If you build a 434, you will have to use an aftermarket block that will be $2,000 by its self. You can get a 434 short block for around $4,000, and then a good turbo kit for around $4,000 and you are already at $8,000 and havent even bought the heads. I would either build a 434 without a turbo with a set of AFR 220 comp package heads, or try a 383 or a 406 with a turbo and street ported AFR 210 heads. One idea is to build a 434 right now, and then in the future when you get more money use the parts you have and change what you have to in order to put a turbo on it. If you built a 434 right now with the 220 AFR comp package heads and used a matched hyd roller cam, you could get a easy 600 hp out of it on pump gas under 6500 RPM. I think that would be enough to get you into the 10's right now, and then in the future when you put a turbo on it you can go really fast.

Good luck

There is not real need to go huge cubic inches with a turbo or supercharger. With forced induction you could not get the power to the street with a turbocharged 305 that was built right. Race track is a little different, but not much. High revving short stroke engines work very well with turbos and they cheaper. A 350 setup properly would make enough power on pump gas to run 10's and 350 parts are real cheap and easy to find. Next time I have to build a shortblock it will probably be a 350 or 377.

Last year the Hot Rod Power Tour stopped in Lake Charles, La. I saw an 90ish full size Chevy truck with a Lingenfelter big block with twin turbos and dual stage nitrous. The owner said the hp was around 1000 without the nitrous shot. He had a speed slip from Bonneville for close to 200mph.

My 350 is 0.30 over, +-420HP (build as edelbrock performance RPM model) , i run whit 150HP nitrous but its not enough to get
the speed i want...

Actually the problem is my 350 as a 10.5/1 whit 64cc alum. head so i dont think i can put a supercharger whit this ratio if i'm right ?

So my best is to build another block , but i want to have more than a 350... More cube is pure power !

I'm interested on the vortec supercharger right now..
How many HP more i can expect whit that ?

and what the diff. "with straight or curved discharge " ??

and you tell 377 , whit not 383 ?

The 377 has the rev ability of the 350 and the large bore of a 400 for decreased valve shrouding and better flow abilitys. It is the same reason that NASCAR guys all run 4.125 range bore and 3.3 range stroke. Heck, a retired cup car engine is pretty cheap and would work real good with boost if you changed to a dish piston.

The vortec will certainly make good power. I have seen sub 10 second cars with that unit. The straight and curved discharge is just the direction the air leaves the compressor. Curved is nice for piping in some situations.

Could you tell me whats the "Ideal" ratio whit
a vortech for maximum boost ?

If i change my piston whit dished one, and is 6inch rod setup will be better ?

· #16 · Oct 3, 2004

There is no ideal compression ratio for "maximum boost".

Keep the compression 8.5-1 or lower and run as much boost as your fuel, compression choice, pistons, head gaskets, rear tires, and drivetrain will allow. Remember that the weakest link will decide what the boost limit will be.

Good luck fella.

The car & rear end can allow mutch over 1000HP i have a moser 12 bolts on it , i just have to make sure i will use the best combo on the engine, since supercharged engine is pretty new to me i want to avoid to get wrong part ...

thanks !

Compression ratio is sort of a matter of application......

If you are building a race only engine, I would say keep CR as low as you possibly can. 6.5-7:1 would be just right and would allow more boost on the same fuel. The problem is that with CR that low the engine is going to be a little hard to start and will have no power in the low RPM and before boost comes in. For an all out race car this is okay, but for something street driven it is not.

8.5:1 will give you room for a good deal of boost on pump gas and the engine will start fine. It will also not completely kill power in the low RPM which will make for decent street manors.

My car is used for street just a little, Most of the time its to go to the track the week end

As i can see
a 434 sbc block
a cr of 8.5
whit 220cc head

Any sugg for the cam, this engine will run a 150 NOS shoot & vortech unit on 1/4m ? i have seen some turbo/supercharger cam profile.. a good sugg. may be ?

Yep, my suggestion would be learn how to properly tune an engine on boost before you even put the thought in your mind about running boost and nitrous. You are asking for a disaster unless you are REAL experienced.
