Joe, your videos inspired me to ditch the crossfire and upgrade to a SPR modified TBI on a Weiand X-cellerator intake. I took the 84 vette out and it outperforms the crossfire through the entire powerband. It is not the same car. My vette has a 350 not a 305. The car is insane fun to drive now. I have heads, headers and TKX transmission sitting in the garage. I need a week or two off from work to complete. Thanks for the videos.
I totally understand your frustrations with the CFI but thanks to your input ive got an 8746 ecu and a Caprice 350 Police car stage 2 chip to go in my 83 Trans am when I put the 355 ive built with Aluminium heads that ive port matched to a Renegade manifold along with some fresh 2" bored throttle bodies. If and when i get the swap done my old throttle bodies may well be available for your car . I'll keep you posted.
Sounds like a nice build you’re doing! Not at all frustrated with the CFI, just out of options at the moment due to the worn linkage and improperly bushed TBs. I’ll eventually put the CFI back on, but for now I’m enjoying how great it’s running 👍
@@Joesmusclecargarage Sorry yes, I just meant your frustration over finding parts, not the actual functionality of the CFI. I love it and want to show what it can Really do. 👍
I only have a 1982 trans am with the lg4 but I really find this interesting, you are expanding the knowledge base and offering ideas and options for current third gen enthusiasts to consider
Either find the Fcar snorkle system or use the throttle body 90-deg elbow plus air cleaner found on the 4.1, 4.5 and 4.9 Cadillac engines for a cold air setup, slightly quieter too. Your vids are great btw, very clear.
I did this swap about 20 years ago on my 84 vette. I used a Holley tbi for a 87-89 Chevy 350 truck. The intake I used was Holleys tbi intake, it came with throttle cable brackets. Mine runs really well too. I think TBI systems run better when they have good flowing ports but a small plenum. Both the stock and Renegade intakes fail to have both of these, the stocker being worse.
Yeah I wasn’t a fan of the Renegade. The only reason I used it was because I got it for free and it was brand new. The single TBI ran circles around the Renegade in every way.
@@Joesmusclecargarage The 87 up tbi v8s had horrible swirl port hears and tiny cams. At least the L83s had decent head ports and a better flowing cam, so you're getting the best parts and letting the motor breathe.
L83s had 624 heads, which are open chamber corks. There is nothing good about them unless you’re comparing them to a 267/307/305 head. Also, a cam doesn’t “flow”. The L83 cam is a broomstick, even compared to an L69 cam of the era.
Hi , I have an 84 Vette with the Crossfire and want to go to that single TBI !!! did you or can you do a video on how to and what to use plz Thanks Tim!
Nicely done, this is just another example of how well you know these cars. If you have the time, I’ve found a carburetor restoration shop that I want to bush my TB’s, take a look the TB balance screw and assess the master/slave throttle linkage and I’m a little nervous about it. My CFI has the factory exhaust/emission system and I will need to address this area soon. I’d like to improve this area but am concerned with messing something up. Would welcome any advice you have. Thanks for all the great info!
Hi Joe, I was wondering one of the next things to do on my 83 305 CFI is to get to the IAC, I changed the coolant temp sensor, CO2, replaced some hoses re possible vacuum leake. The car drives nice at temp, but remains at high revs in neutral once warm. I haven't changed or cleaned the IAC as yet? Any thoughts?
Getting rid of my Crossfire Setup in my 84 Corvette switching over to a FiTech EFI myself, Although not going to lie but the thought came into my mind to try and run 2 systems on the crossfire intake but I think that mod would be too much for my stock cam and heads, Still looking for everything? LOL
Just started the project today! So I have another question, there’s 2 of the idle control valves, where did you run both? Or did you wire them in together
Joe I just purchased 2 tbi systems because I broke the fuel manage block. The problem is the unites I bought I was told that it was for a 82 corvette however; the tbi's are rodchester 24 and the Vett is Rodchester 22. I believe they are for a 305. Not sure if I should rebuild the 24 and put them on the 350? Good deals are some time not as good as you think. Let know what you think or maybe you can use these Tbi units. If you wish to see the 24 tbi I can send you pics to your email.
@@10rrace All CFI throttle bodies are the same; Rochester model 400. The difference is the injectors. You can swap the injectors accordingly depending on application. I don’t have any use for CFI parts anymore. I sold my T/A about 18 months ago
I also used IAC valve off the crossfire injection style, is that okay? I’m only asking because got my whole car together got it timed 6 degrees btdc and fuel wants to spray until start up then stops spraying
@@CalvinReinhart No. Use the L03/L05 IAC. The pintle is different and the CFI one won’t work on the TBI. And like i told you before, you wired something wrong. Either that, or the ECM or PROM is bad. Check the wiring from the ICM to the ECM. Fuel won’t spray unless the ECM sees engine RPM via the ICM.
So I recently purchased a 1982 C3 . It runs decent, but they are so limited on gaining power. Whereas I love how complex the system is, specifically with balancing vacuum pressure; My fear is that the best I will ever get is maybe a 30hp gain. My dilemma is where we have all been before. It's a numbers matching Crossfire Vette (AC even works) but I am looking for 400hp+. Can I get that kind of power from a Crossfire set-up or do I gut the whole top end for a carb or Stinger set-up? You seem to know Crossfires, I am an old school stroker and TBI guy.
First, the CFI is an extremely simple system. It’s really single digit IQ type stuff. You can take it as far as you want to, and can pick up a hell of a lot more than 30 horse. Bump timing and fuel pressure, port the base, remove swirl plates, 7747/8746 ECM swap. From there, the list is the same as any other car; cam, heads, gears, exhaust, converter. An 82 350 had the worst of the worst; corks for heads, broomstick for a cam, horrible exhaust, tall gears, 5550 ECM, etc. There are CFI street cars going deep 11s now.
Joe, did you already have a ported CFI intake on it? Curious as to if just the larger(normal size) intake runners from the tbi manifold made any performance improvement? Asking since a lot of folks ditch the CFI due to the small intake ports and instead of taking time to port the CFI they just punt and stick a carburetor on it? Because you have so much experience with the CFI I would like to ask another question. People claim the small runners were to increase air velocity to help reduce fuel puddling in slower driving. Would porting the stock CFI and switching from 2.83 to 3.73 rear gears not mask or eliminate fuel puddling due to higher rpm’s at same slow speed driving as before? The increased rpm’s would be an increased intake charge too would it not?
I did have a ported base on the car before I put the single TBI on it. And yes, there was a huge performance improvement with the single TBI. I honestly didn’t think there would be, but the difference was huge. The car even pulls harder than it did with the Renegade I had on it a year ago. You are correct about the reason for the choked down runners. It was done to increase port velocity. With the original designs of the manifold, they had problems with poor fuel atomization due to the large runner volume and overall runner length. Changing to a lower gear ratio would not have a positive effect on the puddling issue if you were to have a standard size runner on a CFI manifold base. I have 3.73s in my 83 and when I removed the ported CFI manifold to swap the single TBI on, there was fuel puddled in the manifold. In some spots, the fuel was puddles 1/4-3/8 deep. My manifold isn’t completely hogged out either. I shortened the runners roughly 1.25”, gasket matched, and opened up the entire length of the runners. I also trimmed the swirl plates. Even though good gains can be had by porting the stock manifold, it is still poor, as a result of the overall design of it. All you would benefit from a gear swap is WOT performance. Your low RPM operation would fall to the same issues that were had when the manifold was originally designed.
It’s not a matter of having the TBs rebuilt. I can bush them. The problem is whoever bushed them in the past put bushings with too large of an OD in. The TBs are junk.
Hi Joe I’m back, do got it all together and the injectors seem to prime the car and will run for quick second then quit spraying and died. Any suggestions on what could be going on?
Is it possible to 3D print a lower section to pair w/ the original Crossfire air cleaner or is there too much rise now w/ new intake? Would look great to keep that original look.
I’ve actually been thinking of making an air cleaner base out of aluminum. I have seen a CFI air cleaner adapted to a single 4bbl, which is the same size neck as this single TBI. 👍
Joe, I have been watching your videos. If you plan to put the crossfire back on and sell your TBI set up I am interested. If you are planning on leaving the TBI on and sell the renegade I am interested in that as well. Unfortunately, I just moved out of Los Feliz.
@@Joesmusclecargarage Joe Thanks for getting back to me. I just bought a TBI from SPR performance. I will be converting my crossfire to TBI soon. I am still deciding on the manifold. I have a X-celerator intake, single plane that will fit under my C4 hood, but it will kill torque down low. I am debating the EPS manifold with drop base air cleaner or new fiberglass cowl hood to give me the clearance to run any manifold I want. Your videos have been inspirational, thanks. No one is doing the TBI conversion.
Joe, I was wondering if you still were looking for a crossfire set up as i have an 83 camaro crossfire all still intact and runs. Maybe we could trade your single tbi setup for my setup?

@@Joesmusclecargarage oh men, I also have a 82 T/A with due injections, and planning to upgrade to a duo carburetor, to keep it almost original.....do you still have the renegade intake?
1984 Corvette owner here.. Wondering if you could post the main parts that you used for this conversion? I'd like to copy your setup. Really looks awesome what you've done and don't think it would hurt the value, converting crossfire to TBI. Thank you for your posts!
It’s just a TBI manifold and throttle body from an 88-92 F-body, or 87-95 truck. Everything interchanges between 305 and 350. The only difference is the injectors. Since you have an L83, your best bet is to get a manifold and TB from a 350 truck. Use whatever air cleaner will fit under the low hood of the C4, and you’ll have to change your TV and throttle cable. Everything else is plug and play once you modify the CFI fuel lines for the single TBI.
Did you use a factory throttle body injection intake manifold and if so did you have to modify the center mounting bolts going into the cylinder heads?
I used an L03/L05 manifold and yes I had to elongate the center two bolt holes. I’m eventually going to change to a 4bbl manifold and an TBI adapter plate.
You don’t buy a “kit”. You go to the junkyard with your tools, find an L03, pull the top end off of it, bring it home, and replace the LU5 setup. It’s not hard or time consuming, and even an incompetent can knock it out in an afternoon.

I didn't think there was. But I was curious. I've never dabbled in the TBI world as I have only owned L98 cars but I am looking at some crossfire vehicles at the moment.
@@tymaginnis7746 You can take a CFI car a long way. There are legit CFI cars running deep in the 11s, still reliable, still driven on the street. If you’re good with tuning or know someone that is, you can do a lot while keeping the CFI.
Are you still using the egr valve?
@@bco181 No. I eliminated it.

Can I get the info on swapping the ecm?
You got all the original gauges to read?
Of course. The gauges have nothing to do with the type of induction.
Thank you!
I'll sell you my cross fire stuff 200 if you still need them
Don’t need it anymore. Dumped the car 6 months ago
hi friend have exactly this car and have lot of problems with crossfire please can you say to me the instruction to swap it in tbi single? can you give me your email please? thank you
Joe, what do I need for throttle linkage brackets?
L03/L05 bracket
@@Joesmusclecargarage I found a bracket for a 92 Camaro with TBI on Ebay. Do I need a different throttle cable or does the stock CF throttle cable insert into the 92 bracket.
@michaelhelsley4133 The LU5/L83 cable has a too long. Grab the L03 cable
@@Joesmusclecargarage I finished the conversion. My 350 vette is insane now.
@@MichaelHelsley-p6n Here's the deal, tbi never came with either a decent intake(cfi) or decent heads/cam (L03-L05). Add the L05 intake and tbi to the L83 engine, which have better heads and cam, then you start making power.
