Re: changing crossfire C4 to carburation

I would be all over a conversion if it were my car. where you going to
find the parts for a 1984 crossfire (something that was very limited
production).  

Other poster said this car has a electronically controlled 700R4...is
this true on a 1984 model car? Since I'm not a corvette nut I don't
know but that does not sound right.  You have the lockup converter
controlled by wire but I don't think this thing ****fted by wire
(correct me if someone knows for sure)

Unless you have a pristine car and want to retain the stock engine....
I would basically trash the fuel and intake setup. Install an old
school HEI distributor (like came on a 78 z-28) you can buy a good
rebuilt unit from NAPA. Find out what low profile dual plane intake
and carb setup + air filter will clear the hood. Do away with computer
controls....etc...  Now this based on living where emissions controls
are lax or non-existent.

If you live where you have strict emissions controls... I would look
for a good tuned ****t motor out of a later model z-28 to swap over.

There are a number of companies that make all kind of stand alone
wiring harnesses for projects just like this.  Of course you would
have to know how to work on the car and have good basic mechanical
knowledge of the vehicle and any donor vehicle.

All around road manner and good power....I would be looking for a
tuned ****t setup to use (GM OEM Stuff) not aftermarket. I would look
to buy a complete engine assembly out of a wreck.

Maybe something out of a 02 Z-28 or even a LT-1 engine out of caprice
or road master would be good. 

crossfire to me would be a pain in the ass to screw with, given the
op****tunity to get a new motor with a lot better fuel injection setup.

Was a crossfire not something like to mini-throttle body type injector
setups.  I would go with a more modern fuel injection setup any day
over crossfire.  You can buy entire engine assemblies + ecm + wirining
harness for $1,500 or so.

Seems to me that even the corvette used a transmission in the 1984
year that worked of either  kickdown cable or TV cable.   Unless the
84 has the odball trans mount setup I would change that too, and go
with a more modern version of the 700R4 with TV cable. Does the 84
have the oddball trans mount setup?

If under strict emission controls, you better check the rules on
engine swaps in your area to make sure what you can do in order to
pass emissions / inspection, othewise you may be up the creek.

If you get a complete engine assembly then get the wiring harness 
and the ECM.  Othewise you'll need to obtain an ECM and can use
a wiring harness from painless.   

Swapping all this would not be an easy job. Don't know if that car had
an "electronic" dash...  and if so does the ECM have any direct
control over the gauages or inputs into the dash.  This would be a big
job to tackle, I would certainly do some research, espically if you
will have to pay someone or even do it yourself.
