Stage 2 chip form jet..

the voodoo will have a slightly more choppy idle, but i think they will perform about the same. but again that really depends on the build, im just going off of the specs. i wouldnt do the stage 2 jet chip thing, i have heard really bad things about them. i would talk to one of our sponsers, like solomon. im sure you will be much happier with the results.

cool thanks for tailing me that stage 2 is bad..

i do not have a sponsors...

can i do not have a sponsors...

huh?

i have heard really bad things about them. i would talk to one of our sponsers, like solomon. im sure you will be much happier with the results.

an i sad i have no sponsers...

no look to the right of the fourm page, all the adds. those are our sponser here, with great deals an most of all your f-body needs. thats what i ment when i said solomon aka lt1pcmtuning.com

Personally on your build I think you should look into a custom grind cam. Build a cam to match your exact intentions of the car. Both those cams are gonna want alot of RPM's with those durations. I agree with the JET chip being a bad idea. Those are more meant as an upgrade for bolt-on cars. Your gonna want a more detailed, build specific tune from someone like Solomon as mentioned or another reputable place like PCMforLess or MadZ28. Solomons cable loan will probably be your best bet though for the money.

ok now i got you, and a custom cam i will look in to that thanks..

he wount be able to data log with it being a 93, using the cable loan method. but as for the custom cam that is a great idea, you will be much happier with the out come with a custom cam. then you know you got what you wanted.

what camshaft

IMHO......both of those cams are wrong with stock heads; not enough compression/too much duration.

But you can do what you wanna......your car ;) .

voodoo cam
APPLICATION CAMSHAFTS
Serious Street and Bracket race cam. Needs 10.5:1 compression. Makes uequalled power above 3500 RPM. Works well with nitrous and superchargers.

comp cams
APPLICATIONCAMSHAFTS
Good mid-range with excellent top end. Will require headers, gears, 2500+ stall, & custom programmer. Rough idle.

KW is right you will need to do some head work, P&P and some bigger valves and probely milled. thats what the add says, but i would take advice from people with runnig all short of cams aka experiance.

what about this 200cc intake runners
2.02/1.60 valves
72cc combustion chamber
cast iron head?

or should I buy the valves 2.02 INTAKE AND 1.60 EXHAUST VALVES?

You are getting way ahead of yourself and need to do some research b/f you buy anything or you could end up with a bunch of parts that perform badly.

As KW stated, you will want more compression sense the intake valve will be open so long with either of those heads, switching to a larger combustion chamber will do the opposite, drop compression.

IF you have to have one of those heads I would say at least have the heads milled and use the impy head gasket. Honestly though unless you are building an all out race car both of those cams are way too large for a proper driving street app, but thats just me and its your car.

what about this 200cc intake runners
2.02/1.60 valves
72cc combustion chamber
cast iron head?

who makes an aftermarket cast iron head for the LT1?
you do know that normal sbc heads are different then LT1 heads right?

what about this 200cc intake runners
2.02/1.60 valves
72cc combustion chamber
cast iron head?

......you do know that normal sbc heads are different then LT1 heads right?

And yes......those 72cc heads are definitely Gen-1 heads :( .

KW

so i need more compression so i need a smaller combustion chamber so i should keep my stock lt1 aluminum heads that they are 54ccs ported and polished but that means i will be running 12-13 compression. CanI still run nitrous? ported the intake runner to 200cc. and ported in intake manifold for my 58mm as will...

this guy that ported out to 72cc, Casting #: 10125320, an they are lt1..

maybe frist gen lt1, as stated before just get your stock casting port and polised which will flow great. then get them milled an throw them on with the impala gasket(thinner gasket). and port and poished stock castings are not gonna give you 12-13 compression ratio.

maybe frist gen lt1......

GreenX87, the Gen-1 is an LT-1 (with hyphen).......different from the Gen-2 LT1 (no hyphen) which we have. You will REALLY want to make sure of the product you're looking to buy or you may end up with parts that you can't use.

.......and port and poished stock castings are not gonna give you 12-13 compression ratio.

Very true.

GreenX87, the only way you'll end up with 12-13:1 CR is if you're installing domed pistons (you haven't mentioned that) or.....if the heads get seriously decked.

Some porters will deck heads because due to the porting process, they enlarge the combustion chambers a bit. But generally, they strive to end up with combustion chambers very close to stock (54cc) size.

So the 12-13:1 CR you speak of doesn't make sense.

KW

ok nice thanks alot..awizeking thank you for helping me alot..

thats why we are here bro.

thanks KW for helping me out too as well.

so if I am useing a impala head gasket what year impala? like 93-95? an could i buy it from autozone? thanks

he was talking about a 383 with -4cc pistons. that with 54cc heads has got to be damn close to 12:1. few other factors obviously but he is nearing it.

you will really need to know what you are doing to be playing with nitrous in that compression area. probably wouldn't want to run pump gas through the shot.

Mr. Gasket makes them (part #5716 IIRC) and you have to order them online. As I'm aware of no local parts store sells them, only the 9966 Felpro's which are stock.

So I was right about the compression, so how many horse power will I have with these mods but without the nitrus? or is it better to go all motor? or porting the chamber to 64cc and that will give me 10.5:1 compression ratio.

Thanks 95z for the right gasket part number.

Oh crap :craz28: !

I read the OP's second post and thought the 350ci set-up is what he was going to run.

I just re-read the post and saw that he's looking at a fairly high compression 383....my bad!!!!!

OK, first off......the cams you listed will work well with your 383.

BUT......a custom cam will be a much better choice.

All things being equal, I'd strongly consider contacting an 'expert' to spec out a heads/cam combo. Hell......you're spending good money on the short block, might as well top it off with a heads/cam package that'll give you EXACTLY what you what.

Giving Lloyd Elliot a call would be a good idea in my book!

And apologies for my earlier comments.......I should've read your post more fully :( .

KW

Oh yeah.....the Impala head gaskets are still available at GM (Chevy) dealers......but you may not need it. Make sure your engine is fully spec'ed and get a gasket set that'll put your quench in the .040" to .045" range.

Oh crap :craz28: !

You aren't the only one!

I was thinking stock LT1 shortblock too, hints why I suggested the thinner gaskets.
