Have you seen any Ramjet, fastburn head engines with the ZZ4 cam installed on a regular ZZ4 shortblock? I was thinking it would be around 400 or so HP. I know that the Hot cam gives about 30 or 40 more HP than the ZZ4 cam, but at the expense of streetability.</font>

I plan on a RamJet Fastburn, LT4 HOT cam set up backed buy the T-56 and a 9 bolt with 3.73 or 4.10 gears. That is long term, right now I will have to settle a RamJetted, Vortec headed, L98 cammed, t-5 backed and with a 3.73 10 bolt.
I figure the 430 Ramjet engine with just a ZZ4 cam change should be close to the 395 HP mark NA. I will be running boost, so the HOT cam would leach HP from me because of all that overlap. It would probably cost me a lot more than 40 HP gain over the ZZ4. So the ZZ4 is a far better choice compared to the HOT cam for me. Plus it idles nice and has good low end manners compared to the HOT cam. Win win situation for a boosted REAL street car.
I would love for FormulaJoe to put his power bulge hood on and tell me if it fits or not?
It looks like a very close fit to me! Camaro has a hood line that is a little more forgiving than the Pontiac. The part I am worried about is at the very front by the TB. You know how TPI tilts down there for hood clearence, gonna be close.

You know how TPI tilts down there for hood clearence, gonna be close. I got the 5.7 Vortec T/B in last night. Looks like the same exact piece, but with 2 extra vaccume ports at the bottom of it compared to the regular ramjet T/B. Better to have some extra ports than not enough. I have not measured the throttle bore yet, the wife is home and secret engine project part is pinnned down in the house!HeHeHe
I see no baffle or anything on it and the linkage is the exact same thing as the Ramjet T/B from what I can see of it. Looks like the same d@mn thing, with 2 more ports!

Does anyone know the what the LT1 Corvette fuel PSI is from GM? FormulaJoe said that the LT1 vette was the same reg, so I am looking for an aftermarket adjustable unit or the regular vette LT1 reg with the aftermarket adjustable part put on it? Any ideas? My 730 ECM and connectors just made it in today, no Ramjet stuff yet, it will probably be another week or two. Injectors should be in by Friday.
Joe which end does the throttle cable on the 4 banger have? IS it like the regular 85-88 or the 90 up or what? What did you do to make it work with the regular Ramjet T/B? Also what about the top radiator hose?

You have one of the TB's that I have then!

Those are not vacuum lines, they are coolant ports to heat up the TB blade to prevent icing in cold climates. I'm sure with some modding they can be vacuum ports easily

FYI that TB came from a 4.8, 5.3, or 6.0L vortec truck engine from a 99+ pickup/suburban.
That one is a great one to use for the RamJet Manifold. How much did you get it for?

I'll be a SOB! I had like 30 seconds to look at it before the wife walked in and saw me holding the box and incriminating evidence (TB) from "Super secret engine project!" So I could either deny what it was, silence her, get a new wife or what I did
threw it in the box and ran it to the garage. I bet your right, I will check the porting tommorow to make sure. I think it does have one large port that is not on the regular Ramjet intake. It is the same item as whats on the Ramjet, just with the additional ports. I paid $27 shipped, so that isn't to bad, it looks like it was pulled from a new truck.

Damn hiding parts from wife! I am lmao...You got a real good price on that TB. As I sell them for $45 on ls1.com. You can also find them on ebay sometimes. Someday when I get time, I'll see where all the RJ sensor part numbers come from. As far as what production cars/trucks they came on, that may make it easier to find, especially if they all came on one particular vehicle. It may be easier that way with a donor car, you could get wiring and sensors. Knowing GM it won't be that easy though

Joseph Yeah got it on Ebay. I was going to look for some of those replacement connectors you see in the help section at NAPA, but have not had a chance yet. Then I will just solder and heat shrink them to the existing harness.

Blown85, The end on the old 4cyl throttle cable is just a flat piece of metal with a small circular hole in it. The hole that is in it is not quite large enough to fit over the "tab" on the TB. I drilled it out and put one of those little "clip-dillyboppers" (i think its called an e-clip) on it! Its gonna work fine. Im thinking about making my own bracket though for the throttle cable. Like I said, I have a TPI bracket on there right now and I could get away with that, but it looks funky.
As for the FPR; I had th eRam Jet fuel rails in the speed shop and I mentioned something about the regulator; The guy said that it looked like a LT1 vette regulator to him (because he just ordered one for a customer) and he pulled out the LT1 AFPR and it was the EXACT same thing. This particular one is made by aeromotive.
Just as an update, I got my SLP 1 3/4 headers back from HPC this weekend and put them on the car. Now I just need to get that Ram Jet MEFI computer reprogrammed and I can fire it up!!!!

FormulaJoe The two main questions I had about the reg was how many bolts are holding that thing on, and what is the PSI its set at? The bolts come 10 to a bag! I just wondered if anybody knew what PSI the Vette LT1 reg was?
Is the Ramjet going to clear a stock bird hood where it meets the T/B? The TPI has a tilt to it for clearance in that area. Can you lay a tapemeasure or flatedge or something from the inside lip of each fender accross the engine bay without hitting the top of the intake? I know that it is close and dont want to change my hood, unless I have to.
Didn't someone say something about a cable that could be ordered from GM to fit the F body and Ramjet?

Blown85, I need to go look, but Im pretty sure there is 1 bolt that holds the regulator on. I have no idea what the fuel pressure is set at though. I would imagine that the regulator on the ram jet IS a stock LT1 vette regulator. Why would they make something totally new just for the relatively limited amount of Ram Jet intakes when they have hundreds of these old ones laying around from a mass produced LT1 engine?
When I go home after work today, I will see if I can lay a straight edge over the fenders to see if the Intake will clear the stock hood.
Whats the deal with this throttle cable from GMPP. I heard something about that thing too. Someone must know something.
Why in the heck does this intake only have 1 vacuum port in it? Is this the reason you guys are running that stock vortec unit? More ports?

Just as a guess, I would say 42-45 PSI. I dont really know though. I really want the adjustable one because I am running the SVO 30lb/hr injectors which are rated at like 38psi(or something like that) as opposed to the 42-45 that a GM would run. I mainly want it so I can have the tuneability.

ON the Reg you have two options: 1 buy the WHOLE adjustable aftermarket reg for around $130 or buy the stock part and buy the adjustable reg part that goes on it. I think the price will be about the same either way, I was just looking for options since I dont know a whole lot about LT1's.
I guess the Vette PSI stock at about 47 PSI?
Joseph what's the stock vette LT1 Reg PSI?
And what about this GMPP throttle cable for Ramjet and thirdgens?
Joe would you measure accross the inner lip of the fenders to see how high the ramjet is in your car? I would REALLY appreciate it!!!

"No one here has really came out and said it, but you cannot direct swap a ramjet intake for a TPI intake. the bolt pattern is different."
Yes that is true. But for those people who already have good heads on their motor, just re-drill the bolt holes on the head.
The ports and angles are the same.

There is a throttle cable that works, I have no idea what its from. We tried emailing the GM engineer who put the "yellow" RamJet Camaro (From HR Magazine) together for the part number, got no response though. I'll do some more asking around though. What about one from a 98+ LS1 Camaro? Dunno how it fits on the Pedal side compared to 3rd Gens.

Well, I went home last night and tried to lay a flat piece of wood across the tops of the fenders. Well the problem is, I wasnt able to do so. The ram jet TB was sticking up about a half an inch above the tops of the fenders. Bad news. Dont know if the stock hood will work. I guess its a good thing I have the ASCD ram air hood!
I dont think the LS1 throttle cable will work. Probably wont be long enough. Remember, on the 4th gens, the back part of the motor actually sits behind the windshield, thus, its gonna be closer to the firewall than a thirdgen. (shorter cable)
For now, the only solution I have is to use a cable from a 4cyl thirdgen. These are the longest.

Joe Thanks! More question's: Is it hitting just the T/B or on the manifold itself? What I am trying to say is: since the t/B sticks forward, if it had a downward tilt on it (like the TPI) would it then fall below the line of the fender? I thought this might happen! :-(
Yeah man, I think its just the very front and top of the throttle body that is protruding about the fender line. If it were angled down like the TPI plenum is, it probably wouldnt have any clearance problems.

Joe Would you be able to take some digital pics accross the fenders so I can get a good idea of what type of angle is needed? Thanks for the other info, nobody else has one in a bird, so I dont know who else to ask this of?
Like I said before I dont think the Camaro guys would have a problem since their fenders are a little squared off where our's are more curved.

Im trying to borrow the digital camera from work so I can get some pictures put up. Ill make sure I take a few to try and capture the hood clearance problem.

Joe, can you email me some pics also. I can upload them to my personal RamJet site with the wiring diagrams. I think you are right about the LS1 throttle cable also. I should have thought about that, I work on them all the time...I am planning on getting a 2002 Z(Buy car + slicks = 13's easy) Plus I can do all the warranty work and get paid

Pontiac owner's, the Ramjet might still fit under the steel hood! Turns out after Joe snapped those photos he remembered one real important point, his tranny was not bolted in all the way!(still LMAO over this one) So when he gets it all in the engine might not tilt so high in the fromt and possibly clear. Just thought I should let everyone who was interested know this.
There is a good possibility that it still might clear a firebird hood. We will have to see though. As blown85 mentioned, the tranny is not all the way bolted up to the motor. I didnt bother bolting it up cause its getting ready to come back out this weekend(the tranny). After I get a tranny back underneath it and all bolted up, Ill take some more measurements to see if it will help clearance.
BTW, there should be some pics on their way. I sent them to some people and they are supposed to put them up for all to view.

Hot Rod magazine, among others, have pictured the thirdgen ('91 ?) Camaro that GM put a 350 Ramjet into. The car had been the prototype for the 25th anniv car (Heritage edition?) with the never-released hipo TPI.
One pix of the engine sitting in the car is at:
http://www.fastlane.net/~thartman/RamJet.htm
Observations:
The Ramjet intake manifold is essentially the lower portion of the LT1-type alum intake manifold, which portwise mates to the iron and aluminum LT1 heads, and to the iron L31 Vortec heads, coupled to a larger taller plenum (air box). I am talking about the intake ports matching the ports in these heads, and I am NOT referring to the cooling flow ports. That is why I said LT1-type alum intake, because that's where GM started.
I haven't looked inside a Ramjet to check the runner length (maybe someone can), but the std LT1 intake runners (incl the head path) are around 3" long. The Ramjet MAY have extended the length of the runners within the manifold, and that would help engine filling, and hence torque.
The Ramjet manifold also has a large air plenum to reduce the intake air friction and loss due to unwanted vortcity (as compared to the smaller plenum volume LT1 intake), as well as providing the room for slightly longer intake runners.
Lastly, the tall plenum allows the Ramjet intake to cosmetically resemble the tall fuel injected Ramjet (Rochester) intake manifold from the 1957-1965 Corvette 283-327 engines.
Note that the Ramjet engine uses a very mild cam (196/207 deg i/e with something like .450 valve lift) and yet it makes 350 hp and 400 ftlbs, both at very moderate rpms. GM was able to get that much out of such a low-lift mild-cammed engine because (a) the heads flow so well, and (b) because the intake manifold is vastly improved over any of the L99/LT1/LT4 intakes. The *best* LT1 and LT4 engines, each having cams warmer than the Ramjet, were 300 to 340 hp and 340 to 350 ftlbs, so it should be clear that the Ramjet manifold is what allows about the same hp and much better torque even with a milder cam. FWIW. - Ken

the more and more i read the more and more makes wish I had the money right now to do it, maybe by that time the swap will become a little more know and absolutly all parts will have been tried to see if it works. I first need to get a 350 to rebuild to replace my 305TPI and then save for vortec heads and the RamJet with all assorted parts and why don'y you guys save money but going to the hardware store to get bolts, they may even be better quality.
Just as an update and FYI, I put the ASCD Ram Air hood back on this weekend and it had NO clearance problems. It probably has 2-3 inches of clearance above the throttle body and intake.

No, not yet. Ill let you know when I do though. I did take the tranny out. I was going to put a new flywheel on but Oreilys sold me th ewrong one and I have to go exchange it and put the tranny in tommorrow.
Im 21 and yes I am in college. I go to Oklahoma State University. I am a Fire Protection and Safety Engineering Technology major.

Thanks, just make sure you keep dating this post as you get more and more done. You should be able to have topics saved. That way if someone ask l8r on about this then you can direct them to it. Oh and how old is everyone who is considering this sawp? I am 16 with a good paying job(s).
you can tell this product will be a good seller. I will probably out sell the MR and SR. I orignially looked into it to it b/c it was a GM part and different. People would go ohhhh and ahhhh at it b/c it was so "hard" to install. Looks like alot has changed in a few months. Oh well, I still like it and think it is a great intake.
I think its going to be a good performing intake. It has good flow number from what Ive seen and has some good high rpm capabilities and should promote good torque down low too. I dont know, we'll see.

You guys with the Ramjet setup on hand, please help. I need the part# for the automatic trans/throttle cable bracket.
I have following numbers but my source cant help: 12489585, 12489586, 12489587. TIA, Claus

Right now, I am using a throttle cable bracket from a TPI car. I dont know of any part# for a throttle cable and transmission cable that is Ram Jet specific.
The Crate motor came with a small bracket for the kick-down cable, but it has no hole for a throttle cable. I am thinking about making something of my own that looks a little better than the TPI bracket.

you might want to ask drain89. He came up with all the part numbers for everything eles. How much do you guys think a T-56 would go for in a U-pick it junkyard? I will need that before I slap on the RamJet and Vortecs.
