my friend has an 82 t/a with a 305 cfi. we are wanting to know if we can swap in a 350 short block in place of the 305 and still use all the stuff off the 305. will we have to make changes with the computer, injectors, or anything. can we use any corvette stuff to make these changes. any help will be great. thanks

 

The 350 uses larger injectors.
This is the place for Cross-Fire info:

I can also lend a hand... Trust me, I learned from mistakes along the way.....

 

Yeah, you can swap the stuff over. Now is a good time to port the manifold .

 

With a little labor and not much money these Crossfires run with the TPIs. Given similar long blocks as LT1s, roller cam/alum heads, these crossfires are making over 300hp.

 

Ok, perhaps I should not correct a moderator, but my G-tech time is very realistic. And I will take it to the track when I have the chanse. I was going this summer but they canceled that event.

This is my rwhp / rwtq graph:



rwtq: 350 lbs ft @ 3750 RPM
rwhp: 295 @ 5000 RPM

This picture might explain why ...

 

89WS-6,

Here's a dyno run of a naturally aspirated Xfire. These are chassis dyno numbers, of course.

 

5 years ago running a 355 SBC, 3.42s, CC 270 cam, 95#/hr injectors, 36mm front bar, 19mm rear, full exhaust, Old BFGs ran mid 13s at 99.99 MPH, 747 ecm, my own chip.
Leaving at 800 RPM no power braking, ran 2.0 60's.
From a roll, it suprised alot of people, the lousy 1st gear in it prevented it from doing well at the strip.

 

Don't let the fact I'm a moderator stop anyone from posting their opinion. I might be wrong, but my opinion is that a person doesn't deserve to be labeled a troll for a single post that can only be interpretted as offensive if someone looks at it in completely the wrong light.

Just to clarify, I think CFI would be a cool setup IF it worked. Problem is that the design *in the fbody anyway* is so bad that the car can barely function around town. I will admit the Corvette setup is a better functioning design, but sadly it still doesn't pack a significant punch. I've had personal experiances with 84 Vettes that were slower than my bone stock 87 Iroc thats completely out of tune. So in my experiance to badmouth it a little isn't a huge deal, and if you guys really thought it was a good system you wouldn't let one little ribbing bother you so much.

Regardless I think CFI is in the same boat with the V6's and the TBI cars, until verifiable time slips show these cars running realistic times ranging in the same arena as TPI cars they aren't going to get any serious respect. The L98, LT1, and LS1 are all proven FI platforms, CFI has been around since 82? and still doesn't have any real following. Its not worth fighting over, just know that if you go a different road then other people that you should be prepared for criticism of varying degrees.

 

for future referance to all in the future: j/k = just kidding, a joke, not to be taken in all seriousness.

my policy is to delete and/or edit flames. Its either that or lock the whole thread.

 

Drew,

The fact of the matter is that it hasn't been a little ribbing. The 84 Xfire has been the subject of pity by others in the Corvette community for a long time. And yet the 82 is coveted. Same motor.
Different body style. First and foremost it has been people like Bruce, Jonas, myself and members of the Crossfire Forum that believe the Xfire was dealt an unfair hand by the handicapping that came from the factory. And because of its limited run, we've had to come up with our own fixes rather than being able to pick up a catalog and "buy" our horsepower. So what to you seems to be a little ribbing is really a sorespot for a lot of us. And what we are trying to do is bring the respectability you are talking about.
Bruce ppointed the way for everyone, and I can supply you with my timeslips showing a 13.8@101.3mph with a 2.195 60' time. This was using the stock 3.07 rear with street tires at 35psi. As Bruce said, the hinderance in getting better times is putting that low-end torque to the ground. This isn't meant to be a rant. Its just that many of us think its time to clarify some of the "urban legends" about the Xfire that are spread out there by people who don't know what they're talking about

 

I don't know what your definition of function is, but I have an '83 T/A Daytona Pace Car replica with a Crossfire engine that has over 200,000 miles on it, and it starts up on the first try and has never missed a beat getting me around town. My car wasn't treated very well in its previous life either, not abused or mistreated - just neglected.

If I read correctly Quote; (by 89WS-6) " But you're from overseas, what do you know?" Unquote

That's what I was refering to by someone on their first post on the board to someone who has made several contributions on this site.

Not on the CFI system.

Everybody has their likes and dislikes. That's my opinion......

 

Yeah but only then did I say that, after you couldn't take a joke. Now drop it like the moderator said.
