1. Clarify what is possible
2. Give "Newb's" some "hope"

When I got my CFI car ('83 Trans Am), I didn't know what CFI was except a "rare" injection system. I didn't know how it worked, or what was under that flat plenum lid. When I learned from others what a P.O.S. it was, I have to say I was pretty bummed. That "information" held me back...for a while. I contemplated porting, and removing swirl plates, but nay-sayers told me that would only kill low end torque. So I didn't...for a loooong time, and that was too bad for me. I finally quit listending to "nay-sayers" and went my own way, doing what I thought made sense to me.

After the fact, I'm proud that I got a 305 CFI to run 14.5 with FP adjustments, timing, stat, fan and exhaust. Similar to "CFI-EFI", I've never seen ANY 305 CFI run that fast, with ANY mods. Does that mean that I'm "misleading" or "bragging"? I don't thinks so. I hope that I'm encouraging. Showing what to shoot for. With less than $1500/00 in mods I was running low 13's. Is that "misleading"? I dont' think so. Again it should help to motivate a new and curious owner. That's how I feel about CFI-EFI's posts and you should to. That you "harsh" on him (or anyone) for his bang/buck improvements is exceptionally lame.

Well from reading all your replys and doeing some research....
I am going to do the following: Port my intake and my heads and probrably a performance cam. My exhaust is allready straight and I dont think I can do much with the air intake
Maybe change the injectors and throttlebody

What do you think and if I do all that is it worth it?
I appreciate all opinions
Thanks

on an 84 corvette air passes through the hood into your air cleaner assembly. the air enters the hood from the front of the hood in an oval/rectangular shape hole. generally is what is done is you cut a hole in the plastic peice that is right beneath this hole to allow better flow of cold air into your motor. most mods that i have seen people have taken and placed some weather stripping around the hole that is made to seal it up. if i had access to my car right now id take a picture for you. however if you go to the site i just gave you and searched there im sure you can find one.

I think that changing the TB's is a total waste of time and money. I bored mine out myself and saw very little improvement....on a 400 CID engine. On a stockish engine, TB's will make no difference.

Everything else you have planned sounds great though.

Once again, I am misunderstood. I quoted a post and commented on that post. Unfortunately, YOUR post was quoted in the post *I* quoted. Not only were my comments not directed at you or your posting, I don't believe, even with the wildest of imaginations, it could be said they apply to you or your style of posting. Touchy, touchy.

That, however didn't prevent you from taking a pot shot. My "last 10 posts in this thread" were answers to accusations. If you don't feel they were "meaningfull"(sic) then fine. There is nothing wrong with lurking and learning, in fact it should be encouraged, but if you never had anything else (not you) to post, there would be little need to post. If you don't get my drift, check some post counts and compare them to worthwhile contributions. Now take a deep breath...

You didn't read my post carefully and you reacted ("i have never once in this thread or any other thread") as though I had attacked you. I didn't. Check some of comp's posts. I think his post count exceeds the number of words he has written.

It doesn't. But before you place blame for the deviation this thread has taken, go back and read the OPs question and my reactions to it. I was the first to reply. I have tried to do nothing but help. If answering questions about statements I made while helping, and defending myself against accusations made about that help, are what caused the direction this thread has taken, then I have to plead guilty. Do not the questioners or the accusers have any share in the blame? You went off the deep end reacting to a post I made that wasn't even about your post. Am I such a bad guy for reacting, while you are not? At least I read the posts and responded to what was actually written.

Again, your lurk is not what I was commenting on. And while I admit not every word I write is a gem, my helpful and meaningful posts are well documented.

you are right i thought at first you was attacking me and i apologize for that but weather the post was mine or comps you still had jumped his case for posting which like i said wasnt any less usefull then some of your posts that you was defending yourself as far as the original thread goes. is it any better for you me or anyone to post a useless thread just because we think we are justified by someone elses rant or comment? reguardless of who you was commenting on i still think it was wrong of you to do that even though he has a low post count. a low post count may be due to a # of reasons niether you nor me may know. and your knowlege or helfullness to others isnt in ? here i have seen you post and help others a great # of times. it just seems when someone posts something you dont agree with you have some smart *** remark which is often taken as mean or degrading even though i dont honestly think you intend it to be so it just apears that way.

Shorky, here's the cheap (some free) mods that I did to my 84:

Ported intake, the ram air mod, new 1985 fuel pump, lowered my temperature to 180 with new thermostat and fan switch, cheap set of 1.6 roller tip rockers (with new valve springs and seals while I was there). I also bumped my timing up to 10 degrees initial (34 degrees full advance.)

I do not race my Corvette, but each modification seemed to help. All together, for less than $300, I feel a drastic difference in throttle response and acceleration. I stopped short of modifying the swirl plates, as I did not see any potential for more HP there at the time, but I may play with them a little bit next time I have it apart. Replacing the tired OE fuel pump with the new one for a 1985 brought my fuel pressure up to 13.5 pounds. I think 14psi would be ideal, but haven't gotten around to taking the regulator apart yet to adjust the pressure. Porting the intake is easy to do, as long as you are patient and have the proper tools to do the porting. I suggest looking for a used manifold to work on, so you don't have any down time.

A new cam and heads sounds like a good idea, but IMO you may as well pull the engine and at least freshen it up some if you are going to rip into it that deep. I'm not sure if you posted how many miles are on your crossfire, but from experience adding significant HP to a tired engine could = .
Just my 2 cents. Have fun with it!
