Mike C Posted April 24, 2002 Share Posted April 24, 2002 The electronics are not upgradeable per se, but you could always add somebody else's electronics. Since the controller was designed for marine use, it may be that some of the aftermarket marine suppliers have a CPU upgrade for the Ram Jet. Try Arizona Speed & Marine first and see if they can offer any advice. www.azspeed.com Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 24, 2002 Share Posted April 24, 2002 thats totally true! you can,t easily change the programing on the RAMJET! look here,a far better option(about 1/5 of the way down the page, the holley stealth ram efi) http://www.holley.com/HiOctn/WhatsNew/WhatsNew.html the new HOLLEY STEALTH RAM IS TOTALLY LAP TOP PROGRAMABLE, and makes much more hp, comes with several fuel air maps and on-line help or DOUG(one of HOLLEYS ENGINEERS is available for questions over at CHEVYTALKs EFI forum) the chevy ramjet's 350hp sells for about $5000 delivered,add a new cam ETC and your still stuck crappy heads and a stock shortblock with about 380-400hp for about $5300-$5500. http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=120&pid=463 you can easily build a 383 with AFR or CANFIELD aluminum heads and a HOLLEY STEALTH RAM for about $6000 useing a forged crank ETC. (A HUGE LEAP FORWARD IN QUALITY and POTENTIAL HP.,easily in the 450hp range with careful parts shopping) Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted April 24, 2002 Share Posted April 24, 2002 Hmmmm...good points, but I guess I should have mentioned this before. This is my first foray into the world of engine swapping, or engine work of any kind. I like the idea of fuel injection for two reasons: 1- I don't know squat about tuning carbs 2- This will be 95% a fun commuter, with maybe some road racing (summit point type stuff), so drivability and reliability is very important to me. I'm not afraid of auto projects (I pretty much swapped out the drivetrain and susp of my jeep myself), but I don't think I have the time, tools, or knowledge to start getting into the internals of an engine. Keep in mind that unlike yourself, I'm used to the incredible performance of front wheel drive 4 cyl. cars, so 350 HP sounds likes a lot to me. I'm trying to be realistic about how much HP I really need. Henry Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 25, 2002 Share Posted April 25, 2002 Tim240Z I did it(swapped to crane 1.6 self aligning roller rockers)one of my vettes, a 92 LT1 vette, I needed to remove the drippers that are inside the valve covers, and the valve spring clearance was right on the minimum possiable with almost no extra clearance but still just possiable to get away with. it required very careful measurement and I would not advise it unless your willing to check each and every valve spring and retainer for clearance problems, but yes it can be done! BUT I WOULD STRONGLY ADVISE THE .050 HIGHER CLEARANCE VALVE LOCKS/RETAINERS CRANE SELLS. http://www.cranecams.com/master/vsretain.htm#Titanium%20Valve%20Spring%20Retainers Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted April 25, 2002 Share Posted April 25, 2002 don,t feel up to doing the work yourself http://www.dallasexportsales.com/383sb.html http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=6314&prmenbr=76 http://www.edelbrock.com/automotive/ (Super Victor #2925 ) total less than $5000 Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted April 25, 2002 Share Posted April 25, 2002 According to Car Craft, "The ramjet's computer control, developed for for use in boats, is a completely sealed unit, and it's not easily reprogrammable. This means that you can't go in and change the cam or heads or add nitrous or a blower and reprogram the fuel and spark curves." If that's true, then my lust for the ram jet just suffered some significant shrinkage. I'd at least like to have the option to throw in a bigger cam at some point. Anybody have any conflicting info to restore my desire for a ram jet 350?
