Well, I have read a bunch on here and done the search thing. The following is what I know, and what has been done to make it run better.

-My CFI camaro has a swapped in 350 with an "RV" cam in it. I know using the term RV cam can mean many things, but that is all I have to go off of since I got the car with the motor in it already. I swapped in some 350 injectors (orange/black), had the TB's re-bushed, balanced the TB's, swapped in a TPI pump, adjusted the fuel pressure and it runs pretty decent. I just canned the auto in favor of a T-5.

-I recently got a GM perf vortec dual plane spreadbore intake with a 2 barrel TBI adapter on it. I was going to sell it, but I am wondering if I should keep it and find some vortec truck heads and a TB off of a caprice or something and put this on the topend of my motor.

So my question is, would it be easier to save up for the renegade intake, or can the CFI system and go to an EBL ran 2 barrel TB setup. My goal is some performance with an emphasis on drivability.

 

I just read up on using MAF with a TBI. I like that route better than SD setups. Would that provide better drivability with the above mentioned heads and intake? (the GM perf intake has no exhaust crossover in the intake)

 

i have always liked CF but with the setup u got and the RV cam (great cam, lil thump, and hard pull) id go to single TBI

i got MAP TBI with lots of mods, no emissions, and i got no problems and run better times than TPI's even with my headers still sittin in the shop collecting dust for the past 5 years

i see you are near new orleans we got a car club if you wanna meet up with us myspace link on signature here is the direct link to the forum

Based on the mods you mentioned, I don't think it matters whether you go 2bbl TBI or stay with the Crossfire. You should make roughly the same HP with both engines, assuming you don't touch the short block.

I kept the Crossfire set up because it is unique. With the introduction of the Renegade intake, all factory shortcomings have been cured. It will cost a little more to keep the Crossfire, but there aren't that many systems still around and even fewer that run well. You will surprise a lot of people with a good running CF because most will assume the car is slow simply because it has CF.

 

Umm ya...read more.

I would waste no effort, money, or time on MAF TBI...use an EBL.

 

Thanks for the replies, I guess I will just stick with the crossfire for now and sell the intake and adapter. I caught the motor on fire (no backfire, just went up in a fireball) looking for a vaccum leak today and have to replace most everything on the back of the motor.

I had thought about getting EBL to tune my current setup since it is still running on the factory 305 tune, but it runs good and I am afraid to screw it up and make it run like crap. I need this car to be reliable because it is going to be my daily driver.

 

Well bolt yer butt down...that is a frightening trial by fire...

You must understand from my background how unacceptable any fuel leak becomes...

Now you have a badge of knowledge... ya it sucks,..don't forget the lesson, it could be much worse, I have truly seen hell & I'm sure others have seen worse.

The EBL is an incredibly easy to use and complete system that cannot be matched by anything short of the BS3, Accel DFI 7+,or Holley Dominator systems.

Bless the efforts of the DIY community,.. just avoid the grand-standers and some that might seek self-edification, those who's efforts have shifted from solving problems to ...

Once I get my car back on the road I will try and make it out to a meet or something.

I am pretty sure that I must have hit the dist with the spray and caused it to combust. I guess that is what I get. I dont have access to a smoke machine anymore so I had to go caveman and make fire.

I have read a ton on EBL, mostly to become familiar with what systems do what. It is a lot to take in and I am sure once I get around to tuning it I will also understand better as I am a hands on guy.

 

Absolutely go Renegade. I replaced my CF with a Holley Projection manifold and 7.4L TBI some time ago. Still run that.

Next step is Port Fuel Professional Products single plane EFI with an Edelbrock neck and a LS1 TB unit. I already have the bonnet/ducting/AC and fuel lines and Regulator/fuel pump. Should not be that big a deal to convert.

I converted my 84 Vette CFI to TPI and the overall power and driveability are vastly improved. I will say however that part of the problem with the CFI was a weak fuel pump. If I were to do it again, I would have gone TBI just for the simplicity.

 

Yeah, I guess I will just leave the CF on it, it does run strong considering it is on the stock 305 tune. With the auto it would break them loose hitting 2nd without a shift kit, but like all CFI's it runs out of steam about 4500. I have done all the basic "make it run good" stuff and it was a huge improvement over when I got it.

 

Supr_Fly - Did you port the intake? If not, do it and you will be able to make power up to 5200 or so. Also, install a set of 1.6 rockers.

 

I definitly agree as I've done this with good results. But you also need to address the exhaust side if you still have stock exhaust manifolds. I didn't want to deal with headers so I went with L69 manifolds/y-pipe and 4 bolt cat. You can also use L98 manifolds but you have to swap the air tubes if retaining the smog pump. The CFI cars shared the restrictive exhaust with the LG4
