To make a long story short, what's the "best" way to convert a C3 L82 SBC to fuel injection? I've done several searches - some swear by the TPI setup, others prefer the Super and Mini Rams, etc. My goal is to attain 400-450 RWHP naturally aspirated and then to spray with a 100 shot of squeeze :D. I am extremely confused - some say the S/R bottlenecks at a certain level, other's swear by their M/R setups :crazy: . Lately I've been reading about Hogan's Intakes and Holley Fuel Injection conversions as well as DFI software :crazy: . Should I just buy an LT1 and get it over with?
Sorry for the long post and thank-you for your time and help - I am a beginner as you can tell and any/all info is greatly appreciated!

Hello ! if you have over 400 hp as an goal ,forget the superams etc factory manifolds. Hogans are suberb but i feel they are littlebit overkill for this setup.
As seen in racetracks (drag and "openroad") singleplane style manifolds have worked wery well. I dont like the idea baying "bolt on" kit like holley or edelbrock advertise,they are allways some kind of compromises. do it right at once and bay the components wich are right for your set up and good ECM to control it ,Haltech is one of the leading systems from motorbikes to Formula 1s. check this link ,i am sure their smallblock kit will offer all the power you are looking http://www.force-efi.com/
I used to have a SuperRam on a 383, controlled by an Accel DFI 6.32 ECM. I have a custom Hogan's manifold now, on a SBC 427 controlled by a SpeedPro/FAST SEFI ECM.
You can make the power you want with either the SuperRam or a Miniram, there are plenty of guys on the forum making that kind of power with those manifolds. A custom Hogan's manifold is very nice, but unneccesary for that power level - keep in mind that an EFI manifold from Hogan's is $2450. That's just the manifold.
If I were you, I'd either convert a single plane over to EFI, about $600, or go with the Superram (if you have an automatic tranny) or a Miniram (if you have a manual tranny). Then either add the Holley 950 or Accel DFI efi to it. That's will give you waht you need. But realistically, to make 400-450 rwhp from a 350, you need to really focus on cylinder heads.
Thanks guys for the help, I will be sure to check out that EFI link mentioned above.
Monty, yes I've checked out the Hogan site and d@mn!!! ~$2600 USD for a dual TB EFI Intake :eek: . A friend of mine (ZTurbo) has that setup on his twin-turbo Z28 drag car, but for me I agree, it's overkill.
Why did you suggest the MR with a manul and the SR with auto? I am getting a killer deal on a beefed up 4L60E right now - will it not be in my best interest to mate this with a MR? Also, since this tranny is the "E" version of the 700R4, I'm assuming I will need fuel injection software for sure, correct? (the tranny is from a 95Z28, OBD1).
Thanks all for reading and for all the advice - I said it before and I'll say it again, you guys are a great group!
I suggested the Miniram with a manual tranny, and Superram with an auto, becasue of each manifolds characteristics. Certainly you can use either manifold with either tranny. The SR was designed to improve upon the TPI manifold by offering an extended rpm range and increased mi-rpm torque and power, however, the rpm range is still limited to around 6000 or so. The MR is designed to increase the rpm range even higher and move the torque and power curve up the rpm scale a bit. While the actual low to mid rpm torque difference between the SR and MR is smaller than most people think, the SR is generally know to produce a better mow to mid rpm torque curve.
The E tranny's like the 4L60E and 4L80E need a transmission controller ECM to operate it. There are full manual valve bodies available to eliminate the need for a computer though. You can either incorporate a factory ECM or use an aftermarket transmission controller like the TCI/FAST T-Com, or one of several others. Most start at $600+. The neat thing about the T-Com is that it is fully programmable for shift rpm, speed, firmness and torque convertor lockup via a laptop like the FAST SEFI systems.
So basically I will need a separate device for the tranny ie. a tranny controller AND the fuel injection software ie. DFI ? Doesn't the DFI have provisions for an E tranny and allow me to control the shifts, etc.?
To avoid this hassle, maybe I should just stick with a 700R4 and spend the money I save on the controller to beef up this tranny...
You might want to consider the new Holley Stealth Ram set up, either complete from Holley with Commmander 950 computer, or just buy the intake and rule rails and add your own throttle body, and computer set up. Looks like a good set up. Couple of threads on it in the C4 section
Thank you HW for the info on the Holley setup, I will definitely check it out.

SingrayRacing - do you have website or detailed modlist? Your car is beautiful - and your numbers are right where I want to be as well. Can you give me some info on your setup? Thanks in advance :cool: .
