Thank god the trans am never had that system on it ... But do keep the mystique behind the legendary CFI alive. Were all giving you the thumbs up in you quest for power. :rof l:

 

I think you've made the right decsion get rid of it,part it out, junk it.. whatever. With your lack of knowledge of the CFI its best for the car.

The CFI has been proven many times over and over for reliability as well as holding its own on a track. Good luck in your other ventures with your other vette. It may be more suitable to your needs.

 

Yeah the though of unleashing this CFI's full potential made me quite scared of the car which in itself is another reason I chose to part the car out. I love vettes but this mean machine always made me nervous when I floored it so I bought a 90 vette to restore since I feel a little less intimidated by it's power verses the CFI's

 

As an 84 Corvette original owner, I have been following this thread. Let me say that there is no wrong or right when it comes to a person modding their cars. I have run the whole gamut with my car. After I bought it new, I was going to just polish the wheels and put in a K&N air filter. Then I added nitrous. Not long after I cracked the block when a nut braised onto the air cleaner hold down bolt came loose and was eaten by the motor. Switched to a 70's block with 4 bolt mains, ported and polished the heads, changed cams, ported the intake, larger injectors. Finally decided I could go no more with the crossfire and carbed the thing. Then went with a 383 and an extrude honed SuperRam set up. Now I have a 406 with the SuperRam. I have tried over a half dozen cams over the years and spent enough to buy a Ferrari or two. This car is my hobby and I enjoy different phases of buildups. Was I wrong to do any of the mods? No one can tell me yes or no because there is no answer; sort of telling someone he is wrong for liking the color blue. What is important to one person may not be important to another. This thread started out with the op proud of doing what he could do with his own hands to improve the output of his crossfire, and has evolved into a somewhat nasty clash of egos. Let's remember we bought out Corvettes for fun and enjoyment. Willie

 

And you should!...
Again you have missed a point.

you and 85 ... learn this word ..know it , understand it, then try an use it.

com⋅pre⋅hend  /ˌkɒmprɪˈhɛnd/ Spelled Pronunciation [kom-pri-hend]
–verb (used with object)
1. to understand the nature or meaning of; grasp with the mind; perceive:
2. to take in or embrace; include; comprise


I do understand how much different the 350 Short block under the CFI intake is just so much different than any other 350 out there. So it can get awfully confusing.

 

Exactly. What he^ said.

 

Well put, Willie. Sounds like you and your '84 have been on quite a journey together, that's the kind of relationship I'm trying to forge with my car....does that make any sense ha ha!

 

You're wrong Kangi!! !

 

To the original poster. My hats off to you. TO have the gonads to pull off your own intake and do some porting is 90% further than many so called enthusiasts have ever gone. They will never understand.

I'm not expert on porting but I've seen heads finished porting and look rough and just some fine polishing brings them to life. You are not far off.

I want to laugh and comment about carbs but I wont. Everyone can also mention other options but what is the cost to buy another manifold and associated parts? This man is doing the work himself and thats where the true beauty is.

If we all had money I'm sure we'd be lined up at Katech or Lingenfelter or Callaway (me). But we dont. Great job look forward to seeing some results or finished work.

 

Love it

 

...well minus the broke parts, sweating, crying...y'know the good parts!!

 

Don't forget the knuckles.

 

Well congrats on your journey OP, you are seeing the 2 different points of view here, and obviiously you still keep your path.

I give the guys credit who made it work, or make it work, but we all know it is what it is period.

I say that because if I had an 84 it would be carb, I dislike my tpi compared to fords unfortunately.

I like LS's though LOL, any chance you might upgrade to a LS thread to keep us on our toes here.
LOL

 

How much of a difference was the ported intake manifold from the stock manifold? How fast were you with the crossfire before you went to the carb?

 

I wish I could tell you. This was 2 decades ago and I did not document the changes and the improvements with 1/4 mile times. A lot of the changes were done in mass so I couldn't begin to pinpoint the benefit of each. I'm buttoning up a freshened up motor that I hope will run low 10's next week. Sorry op, off subject here.

 

You are lucky you can't and smart if you don't. He will beg for answers and then argue with you about what you give him. He will issue a challenge, then back out. He will put words into your mouth and then ridicule you for what you never said. Any assistance you give will come back to bite.

For instance, I never said My car would run 12s. The man has a comprehension problem.

No good deed you do for this this guy will go unpunished.

To kangi,
Keep up the good work. If you have any questions for me, please e-mail or PM me. I am happy to help any sane, rational, honest, well intentioned, car guy serious about what he is doing.

RACE ON!!!

 

Way to much drama for me to read all of the posts.

I just wanted to add that in our local club we have a couple of guys running in the low 12's with crossfires (yes still with the crossfire induction).

If you want some contact info just PM me, I'm sure they would not mind answering some questions.

 

Wow... thats impressive..
I thought the record for a CFI was 12.48 in a quarter?
What are they getting?

 

Thanks for the offer I just may take you up on it.

Well, I've still got a lot of porting to do, and with the good advise I got from this thread I'm more confident in what I'm doing. I'll start a new thread when I need a little more attention

Oh, almost forgot, next tuesday I got a dyno run to establish my baseline. I'll post the results.

Thanks, everyone!

 

This is getting really good, finally a guy that will have a baseline to work with, if you could, could you do a 0-60 test before and after too. A stop watch will do. And don't forget your SOTP dyno we will need those numbers as well. Good luck and rock that dyno hard
