its about time for my beloved fbody to get a new engine. so being that im gonna get a gmpp crate, im thinking ZZ4 or RamJet350.
i think im gonna go with the ramjet because it already has a big enough induction. as with the ZZ4 i would have to do that part.

so what all is involved in planting the ramjet into my 92' 305 tbi camaro w/ 700r4.

tia,

It pretty much drops in, comes with it's own ECM and harness also..


But for $5,000, I'd build up a mild 355, throw on a DFI setup and a blower!

would the ramjet 350 meet emissions in most states? I asked about it in colorado and
my buddy at the local chevy dealer said no.
Would the induction fit under the Hood?? I got to check out the hot rod article!@!.....bob

No, it won't meet emissions. There's no oxygen sensor so it runs completely in "open loop".

I agree with 812many to a point, though. Unless the price of the RamJet 350 came down a bit, I'd go some other route. I could live with forking out a little under 4 grand for it, but it's going for about $4800 to $5000 right now. It would actually cost you a bit more in the long run since I think it's designed for older 4-speed automatic transmissions like our 700r4s, but the computer that comes with it doesn't have any provisions for the transmission, so you have to get a standalone computer to control the tranny.

With the way things work,give GM a little time and a cheaper price as well as an emissions legal version should come around within the next year if you can wait that long. Perhaps someone else in the aftermarket could reprogram the ECM for O2 sensor use for closed loop.

the 700r4 doesnt need a computer to work properly, the 4l60E does and that didnt come out until '94. Think of all of those guys with classic camaro with 700R4s that dont have any computers on board

700R4s have a computer control. the torque converter lockup is computer controlled. not sure if you really NEED it or not, but it is there.

I'm seriously considering this swap also.

Jim Pace has the Ram Jet for $4199.

Yeah I just picked up that issue of Hot Rod and read that too, what a shame. I can't believe GM would think something as simple as welding on an o2 fitting was too complicated for someone doing an engine swap. Dam shame...That engine looks hott under the hood...

Well, wait a second. Who says that you HAVE to use the MPEFI controller that comes with the RamJet?

In a basic sense, the ecm in your F-Body only cares about sensor input, ergo, if the RamJet
can be fitted with the proper sensors why would it car?

So, the basics of a modern GM EFI system are:

coolant temp,
MAF,
TPS,
IAT,
Knock sensors,
MAP.

So, if you could fit the above sensors in some way to the RamJet, you would be able to drive the engine with the factory ecm and a custom program I'd think.

So if its possible for Howell Tech to convert a TBI harness to plug and play TPI, then why can't they convert a TBI harness to drive the RamJet?

GhoSSt I'm sorry, but the whole idea of the RamJet350 is for an EASY EFI swap. It comes with everything needed specially for that induction system. Why not just get a 400 and a Miniram if you want to run a stock-like wiring harness?

Remember he asked 'so what all is involved in planting the ramjet into my 92' 305 tbi camaro w/ 700r4.'

He didn't ask for easy, he asked how to make it work. :P J/K

But, actually I spoke with Fuel Injection Specialists AND Howell about this at length, and both of them agreed that a TPI harness will run the RamJet just fine. The only thing that Howell mentioned was the lack of EGR on the RamJet would make (visual) emissions tough.

The Hot Rod article is kind of sketchy, but when you think about it, what is really different between the RamJet and any other modern EFI engine? It uses standard sensors, the ECM doesn't care what the engine IS so long as it gets back a set of understandable values from a given set of sensors. And given that we can chage the values via prom burning, I think the RamJet is VERY doable. Cost prohibitive perhaps, but no more so than a 400/Miniram swap.

I did not say the TPI harness would not run the RamJet intake, but that it would be a waist to buy the whole package and do that.

Now if you were to just pickup the intake, fuel rails, LS1 TB, 24lb LT1 injectors and run it with the stock TPI harness it'd be a great buy. Those would be the only things you'd need besides using fastburn heads or Vortec heads and having to fab some new throttle cables. Or at least from what I've gathered so far.

I talked to Jeff Tuesday (I think) @ SDPC and he's waiting for the parts to become available to do just that. I agree, its a cheaper way to go, to use the service parts and not throw away the MPEFI controller/harness. I wish it's fit under the hood of the Caprice. Thats EXACTLY what I'd do, convert my TBI harness to TPI and stick in a RamJet setup with fastburns on my L05.

I'm not sure if the 24lb LT1 injectors will fit the RamJet, but if they do then they'd be perfect since many TPI owners use them, they're cheap and the RamJet normally comes with 25lb injectors.

Yeah, I've already checked about that. AcDelco, Bosch, SVO Ford, will fit. 24's and 36's for those... special occasions.
