Will a 350 Ram Jet crate engine fit in a 90 Camaro or is the intake too tall?

 

it will fit the same as any other 350 would, as for clearing the hood, just get a cowl hood if it doesn't, but i would imagine it would.

 

it will fit gm put one in a 90 rs looks at home in the third gen

its lower then a stealth ram....


looks good in there too

 

i think the ramjet is a good motor. but the only thing i dont like is that you cant modify it at all! it is what it is and thats that!

 

Why not?? A cam change and some port work would be a change right?

 

the ramjet comes as a complte 'kit'. engine wiring and computer. its a sealed unit! you cant change the chip or modify it. if you wanna add parts to flow more air, its pointless cause the computer will only send enough fuel to feed the parts it was originally designed to work with.

 

Conclusion

Converting to electronic fuel injection can be a daunting proposition for a first-timer unsure of the intricacies of this “newfangled” technology. With its supplied computer and wiring harness, the Ramjet is a true turnkey, plug-and-play EFI crate engine. It fired up and ran flawlessly right out of the box with no tuning required. [B]However, the Ramjet’s computer control, developed for use in boats, is a completely sealed unit, and it’s not easily reprogrammable.[B] This means you can’t go in and change the cam or heads or add nitrous or a blower and reprogram the fuel and spark curves. The Ramjet is what it is and that’s that, which is a great crate package for anyone who wants the convenience and drivability of EFI without major cost and hassle.

If you look hard enough you will find the ram jet 430 with aluminum heads and the hot cam. They just reprogram the GM EFI 3 thing and off you go. It is about another 1000 for the upgrade but well worth it in my book.

 

and i think its a little pricie for 350 hp. i know it is entirely complete! but almost 5000 buck for 350hp. i dont know? i mean for $2200 you can put the 350ho under your tpi, with a little modifiction. or you can pay $3200 and get the complete 350, carb to pan! thats easy! you can easily built a motor yourself cheaper and get the same results if not MORE power!

 

yeah the manufacture has to prgram the computer. sure the 430hp is great. but not the ramjet 350. still you cant modify the 430 either! you can get the engine with more power but YOU personally cant modify it!

 

Well like all current EFI systems they adjust very well to mods. Don't worry about changing it so much. That is why it is computer controlled. If you keep the mods within the realm of tunability it isn't that big a deal. Most current EFI systems don't benifit from ECM changes until over a hundred HP is added. Plenty of radiacal heads and cam combos out there on stock OBD1 and OBD11 tunes for LT1's and LS1's alike. Sure you can gain a little more from a tune bit its not like old PROM style chips where they have set parameters that never change. Lots of LS1 and LT1 guys have over 350 to the wheels before they even change the ECM.

 

you can have the small ecu reprogramed by arizona speed and marine for a veriety of combos,went through this a year ago,the factory setting has it running rich so A.S.M. has an o2 mod,can also tune for larger cams,bigger valves etc....the yellow r/s with that 350/6spd and 4.10s ran a 13.10 not bad in my book,only drawback NO EGR provisions....

 

btw, nothings stopping any of you from sticking the ramjet manifold, fuel rails, ect on a car and using a TPI ECM.......

 

That topic was discussed a couple of years ago, if memory serves (someone was doing it). There are some sensor issues. And lack of EGR. But, you're looking at PROM tuning, anyway.

I don't know anything about the RamJet except what I've read. I've read it's an open-loop system, so if ASM is making a feed-back system, that would be a big improvement. If it is open-loop as-delivered, the mag was pretty irresponsible passing it off as a viable street engine (can you say emissions testing?).

I've also read the ECM programming is not friendly to changes, so as mentioned, you change something (like cam or head flow), you go get a different ECM. Perhaps ASM has also addressed that.

 

yea you have to burn a PROM for the EGR delete.. but as far as i recall, thats it...
there was a thread a few weeks ago with someone trying to do this.. apparently, the manifold isnt that much at all from GM..

ASM is making a closed loop version and conversion kits... i also understand they will do custom tuning for that ECM...
the magazine and GM point out several times that this engine is NOT for "emissions controled vehicles"... so technicly, its a "illegal" swap.. like the stealthram.

 

the gm catalog says this engine is a performance upgrade for cars and trucks up to 1974.................
