I also found this! This casting is so thin that it will surely break off and fall into the intake ports!! I'm going to have to break this off before putting the intake on the motor.

Does the Ram-Jet MAP sensor work with a 1227730? or do you have to use the L98 MAP? I have a new intake and used throttlebody here trying to piece everything together. I've had the heads for a while and I think I'm going to use a ZZ-4 camshaft.

I think the Ram Jet MAP will work, but I can't say from experience. I have all the parts to finish this motor except for the roller rockers...I'm getting a little upset about the wait. Hopefully by this weekend I'll have the motor running.

Here's the latest progress (still waiting for the rockers).
The March 2004 Car Craft article seems to be wrong. They said they drilled out the pushrod holes to 3/8". I put a 3/8" drill bit in each slot with a lot of extra room.

Wildside when you get a chance could you do me a favor? I'm curious what size the throttle blade is? thanks John

I'm pretty sure the lifters and pushrods will work, but it never hurts to be exact!

what you need is a pushrod hole elongation tool....the tool slips in the existing hole and acts as a guide to hold the bit just on the edge of it.
that way, you drill your round hole into a oval.. and the oval allows more lift.

After I get the motor running, I'm thinking about selling it complete with starter and all accessories for $4,000. That's a great deal considering the Ram Jet crate motor doesn't even have a water pump and is about $1000 more.

Yes, the crate motor DOES come with a water pomp. It even
comes with spark plug wires, air filter, spark plugs, oil filter
and everything else to wire up the motor with. It's more
complete than you think!

Yes, I agree! The motor DOES NOT come with an oil dipstick,
however there's one pictured in there!
The T stat housing is NOT chrome plated either!
The engine coolant temp sensor is on the opposite
side.

*Update
I loosened the rocker arms a bit and the motor ran for a short while. I'm going to readjust all the valves this afternoon and I expect it to run just fine. My batteries died last night from all the cranking (even stole the battery from the Firehawk).

I finally got this motor running. The link to the video is below. The motor idles very steadily at 700rpm and it's very responsive.

So that's on a 1227730 with a stock chip? and it idles well? have you had a chance to check the BLM's? I was wondering how the 109 lobe center cam would work with SD. Very cool!

WOW! I can't wait to start my Ramjet 350 up! I am still
working out some bugs not even related to the motor.
My power steering pump needs to be removed and taken
apart to reseal. It leaks out the back and it's not the line
going to it. Also my pinion seal keeps leaking out from the
bottom lip off the housing. Was aftermarket seal, now I
installed a factory GM one. Hope that's all set. Once those
leaks are fixed and once I get an upper rad. hose to fit
right, I can move on to the wiring of the motor and start
up the freakin thing! Wish me luck! :hail: :lala:

MegaSquirt & RamJet
Just wondering if you might be able to make a harness to hook the RamJet up to a MegaSquirt ECU i want to put FI on my '85 with a 383/425 GMPP Long Block and the RamJet would be perfect, but I want to be able to make changes and adjustments without having to burn PROM's....

Thats an interesting engine setup you put together. Too bad you can't take it for a test drive. I'll have to stop by and see it run. I want to see how smooth the idle is. Did you make any changes to the bin file?

Congrats on finishing up the project! Sounds nice, I played that video over about 5 times in a row just to hear it purr. My wife finally said thats enough.
Anyhow, I finally got my RamJet setup in the mail, actually this morning. It's beautiful! Man, a very nice piece altogether, IMO.
S10, can I ask you a quick question if you woudln't mind giving me a lead here....for the fuel hookup, would you be willing to share what sizes/type of fittings are needed for the regulator and the fuel rail inlet? I'm not too keen on fuel fittings. I would guess NPT, but I really have no idea. And I don't really want to lug my whole setup into the hardware store, nor tear it apart to take just the rail/regulator. Any info appreciated!

The fitting on the back of the passenger side rail (fuel inlet) is a NPT to -6AN fitting. Aeroquip makes this fitting. I don't have the part number anymore.
You'll have to use two 90 degree -6AN fittings. The fitting on the passenger side just clears the distributor cap. It's so close that you can just slip a piece of paper through the space between the fitting and distributor cap. You might be able to get away with a 45 degree fitting coming off of the fuel pressure regulator, but you'll be happier with a 90 degree fitting.
Expect to spend the following:
$25 Fuel Pressure regulator fitting (from TPIS with shipping).
$30 Two 90 degree -6AN fittings
$10 NPT to -6AN fitting from Aeroquip
It's expensive, but it's the easiest way to go.

Thanks for the info, much appreciated! Now the -6AN adapter your talking about, do you mean the aluminum male/female piece that came on the regulator already? If so, ya I have that so that's one less thing I need. So you say that is -6AN, that helps a lot, so then the only thing I need to figure out is the NPT size on the back of the fuel rail and get a NPT to -AN fitting and run my lines. Thanks again!

BTW, I will be PMing you S10Wildside, for a question

Well, the project is over. Someone in Tennessee purchased the engine from me. I loaded it in my truck yesterday and dropped it off for shipping. My Silverado SS only has 345hp/380lb.ft. and I couldn't help but feel a little jealous that it was hauling a 350hp/400lb.ft. engine. The next project is to finish the Firehawk.

It clears my hood, although it is close. There is absolutely no room for a STB...even a fabricated one, as far as I can see

So this thing actually fits with the power bulge hood without cutting any braces? You got any pics underhood? I was going to to do the ramjet two years ago then the HSR came out and then the Vortec unit. How did you manage to get the cables setup for the TB? I still have a Vortec TB with IAC and TPS I can use.

I'll try and get some pics next time I am home. I have some of the engine sitting in the car, do you want the actual hood almost-closed on it or what?
No cutting is required. I used a Lokar braided SS cable for an LS1 for the TB to pedal.

It's not tuned yet. Haven't found much time to mess with it lately, the dist. needs a new ignition module right now. It runs but I haven't driven it any further than out of the garage to prevent asphyxiation. Lemme see if I can find a pic here....
Ah, here we go.
There's a lot of loose ends yet, and the car is filthy, so don't mind that...that's what happens when it sits in a garage for a year.

Just my 2 cents,
The crate 350 PFI Ramjet motor runs awesome. Only
need to break in the motor and go. NO tuning at all.
Powerband is great. Need to run custom lines,cables,
etc. Fr my motor, I made custom fuel lines and
modified an LS1 cable to fit the gas pedal to
throttle body.
Also, must cut braces on a Camaro hood to clear
the intake. Cannot use a STB either.

Yes, it IS my motor mounts. I am using All poly mounts
and bushings on the car. The polyurethane mounts
increase the height to about 1/4"-1/2" more than stock.
The down side: had to cut the braces in my hood (big deal!)
The up side: increased clearance for my 1 3/4" headers.
