better how?

raw flow numbers? Stealth Ram
easy of install? Stealth Ram
price? not a huge difference if you consider time an issue, but if you consider only the cost of the intakes and fuel rails, the LT1 has a distinct advantage. The stealth ram is a direct bolt on tho, other than the 87-up head bolt hole issue and a few other minor things.
hood clearance? LT1 definitely
distributor clearance? they both kinda suck, but at least the stealth ram intake comes ready to accept a distributor.
emissions legality - 50 states? neither
ease to obtain? LT1 intake by far

That being said, those are not the only two options out there. The ramjet/vortec head combo is pretty stout, and there's always the miniram and superram, and the 8000 aftermarket variations on the stock long runner TPI setup.

For me it was a no-brainer. I'm building a stout 400/406 with some serious flowing circle track car heads, and I'm gonna go about as far as I can go on an EFI friendly, boost friendly cam. The LT1 intake wasn't gonna meet my flow needs. I also have the early style head bolt pattern, so the stealth ram was the obvious choice. I actually had an lt1 intake manifold, and i sold it.

ram jet?

I was wondering about performance differences.
Also what's this ramjet and the price. where can i check it out.

I'm wanting to ditch the stock TPI For something loke the stealth or lt1. I dont want tp spend$300 for runners and another $400 for a base. It just doesn't make very much sense hp to $

GM part number 12489371... about $450. It looks very similar to the StealthRam or early mechanical fuel injected 'vette intakes. It uses Vortec heads and late-model 3800 throttle bodies.

well the LT1 intake has flown enough to get cars in the 150mph trap speeds. is your 406 going to be that stout?

Im getting my LT1 intake done by John Millican ( www.lt1intake.com ) I was thinking of the stealth ram. but if the clearance is that close. Think of it while the motor is revving. Also Im tired of multi- piece intakes. (more chances for vaucum leaks).

But thats just my opinion.....

ram jet

Well http://www.gmpartsdirect.com has the ram jet intake for $380 and you still need a throttle body fuel rails TPS throttle cable bracket etc..... lots a little stuff. Basicaly the Stealth, Lt1, and Ram Jet look similar and are around the same price. what I want to know is what are the performance characteristics?

first off, if anyone is interested, i have a ramjet TB with the sensors on it i'll sell for $50. I've actually convinced myself to do all 3 at one point or another, so i have the extra tb left over, and i sold my lt1 intake a while back.

Performance characteristics aren't the whole story. If you go with vortec heads, you want to go ramjet, if you go with standard style heads, it's easier to go with the other two. That's a given, so keep that in mind....your head choice dictates intake choice as well.

As far as performance is concerned, head and cam choice dictates a lot more than the intake does, but the stealth ram outflows everything in sight, so it will make more horsepower in a highly modified engine. But it's probably not the optimum choice for a street engine, because you will lose low end torque no doubt.

With the flow numbers generated by the stealth ram, it's gonna be able to support pretty much any small block you bolt it on to.

There are 9 second LT1 intake cars out there too, so the lt1 is definitely not a limiting factor by any stretch of the imagination either.

I don't think the ramjet intake is gonna go as far, but then again, neither do the vortec heads.

I want to know how you come up with that statement. Show me the flow numbers for the HSR, LT1, Superram and RamJet intakes please.
If you cannot produce this infomation then do not post BS.

John you are absolutely right. I don't have flow numbers, so people reading this post, do not take my OPINION as absolute truth by any means.

My role is an unbiased observer who has had in his personal possession both the LT1 intake and the stealth ram, and I have been able to hold in my hands and take a look at a bare miniram intake as well. I have seen the flow numbers for the superram, and I'm not impressed. It still comes back to just how far one can go with a tpi-based lower intake and "long" runners.

The LT1 intake absolutely has more internal air obstructions, which no doubt would have an effect on flow numbers and horsepower. What effect has not been quantified that I'm aware of, but if I were a betting man, I know where my money would lie.

So that being said, I do apologize, and I should have been more clear in my initial postings.

However John, you have an undeniably biased view on this considering you are personally profitting off of the LT1 intake. So no offense intended at all, but whatever great things you have to say about the LT1 intake do need to be taken with a grain of salt. I have no doubts in my mind you are a great, trustworthy guy from what I've read on this board, but just because you say the LT1 intake is better, doesn't make up my mind for me.

The same holds true of any posting made by Holley's Doug Flynn as well.

Has the stealthram made 9's on a sbc?
Super ram? Just a few?
Miniram? maybe one?


I know a whole lot more LT1's have seen those numbers than the rest

With or without forced induction? I'm sure there are more minirams than superrams in the 9's without forced induction... I'm curious about this debate as I'm going to be building a big cubed sbc (400+) but I really want to keep my stock tpi intake hehe. I was wondering how far I could with an edelbrock baseplate siamesed as far as i can go with siamesed runners and basically completely empty plenum hehe. This could be a potential money maker people!! Which is of course why i want to keep it basically stock looking .

Hey Wraith, your right. I do have a biased view of the LT1 intake but I didn't say it was better then the others. It just appeared that way.
I didn't want to start an argrument (I don't believe we did) because you seem to be very knowledgeable in your statements so far. You always post great detail and people DO believe for truth what they read as long as someone says it's so.
I would like to see more people back up what they say with facts or just state it's their opinion, that's all.

Now, with that said, lets continue hottrodding!!!

nah, no argument......just some friendly exchanges

You called BS on me, and you definitely had a point..

FYI, I think 99.99% of us will agree there is no yes or no answer to which is better, stealth ram or LT1, and that is the original question at hand.

well it goes without saying that there's probably a lot more LT1 intakes out there on faster cars, because there are more lt1 intakes out there in general. There are tens, if not hundreds of thousands of them out there on 92-96 vettes, 93-97 f-bodies, and 94-96 caprices, roadmasters, etc.

the amount of superrams and minirams out there might be significant, but it's nothing compared to the LT1 intakes in use out there.

And the stealth ram and ram jet are relative "babies"

oh, and there are long runner tpi cars in the 9's as well, and most of us will agree that intake setup has a significant amount of drawbacks.

So Far I am VERY happy with my LT1 intake!!! It pulls very hard all the way up to 6000 rpms where I usually shift it at. I have yet to make it to the track but it is running VERY rich and till I get it tuned out I will stay away.

The one in his trans am looks like the CC305 cam. You can get it from Thunderraccing.com (one of the sponsers) I just ordered mine. here are the stats
DUR: 220in/230ex
Lift: .510"in/.510ex .544/.544 with 1.6ratio rockers
LSA :114
alot of LT1 guys seem to like this and im going with an LT1intake so I thought this would do me good.

I am 90% sure that these numbers are correct, 08-305-8 comp cam. I threw out my box 2-3 weeks ago and I can't find my cam card either, but im pretty sure that's it.
