Lately my 1982 Chverolet Corvette Collectors Edition with the 350 CI Cross Fire Injection Engine has been stalling and missing. I have change the Spark Plugs and have burned the fuel down to .75 gallon and refilled it with fresh fuel a bottle of heat and a bottle of Fuel Injector Cleaner and have run that through the engine and it still has the above symthoms. Please tell me what I should do to solve the problem. Thank you.

Yes, you will need to transfer all peripheral sensors and the intake and injection from the Camaro engine to the Corvette engine, But the beauty of a small block chevy is that most everything interchanges. One thing to make sure you get correct is the flywheel. Count the teeth and make sure they match. You will need the correct balanced flywheel and balancer for the Corvette engine, and double check the length and rotation of the waterpump.

Cam companies usually have help lines to match a cam to your engine configuration . They have custom ground profiles that will work with your SBC .

From this chart - I think you may be misreading the number - 3970010 is possibly the actual number: Which makes the engine pretty old 68-72 350 V8 - 4 bolt main. I included past this number so that you can see that the number you posted doesn't actually exist. And thus my conclusion that the 9 is most likely a 0. Hope this helps. 3970010 350 69 Corvette late 69,4 bolt main 3970010 302 69 Camaro Z/28,Late 69, 4 bolt main 3970010 350 69-79 Truck 2&4 bolt main 3970010 350 69-79 Pass,Chevelle,Camaro,Nova,MonteCarlo 2&4 bolt main 3970010 350 70 Corvette 300,350,370 HP 4 bolt main 3970010 350 71 Corvette 270,330 HP 4 bolt main 3970010 350 72 Corvette 200,255 HP 4 bolt main 3970014 350 69-77 Pass,Chevelle,Camaro, Nova,MonteCarlo 2 or 4 bolt main 3970014 350 69-79 Truck 2 or 4 bolt main 3970014 350 72 Corvette late &undefined;72,200 HP,255HP 4 bolt main 3970020 307 68-73 Pass,Chevelle,Camro, Nova 3970020 307 69-73 Truck 3970024 307 69-73 Pass,Chevelle,Camro, Nova,Truck 3992386 327 68-69 Pass,Chevelle,Camro, Nova,Truck Large Jounal

do not need

Intake manifold gaskets are a common place for a coolant leak. I have changed several of them because of this. It is common for them to leak to the exterior. They will also leak to the inside and then will cause internal engine damage. It is not generally a really expensive repair unless you have damage from overheating your engine.

Not sure I understand your question...the stock motor on the 1984 Corvette is the "Cross Fire Injected" 350 V-8...Hope this helps.

Change the fuel pump in the gas tank.

i would clean the injecters

Possible causes, and in an order of where to check first:

1.Fuel filter - Located along the Right frame rail, close to passenger door area.

2.Fuel pump - Located inside fuel tank.
[Electric fuel pump. Pressure should read between 9-13 PSI.
The Cross-Fire Injection unit, is in reality,
Two- Throttle Body Injection units. TBI. ]

3.Fuel strainer for fuel pump. ('Fuel sock')
Located in fuel tank, attached to fuel pump.
The fine mesh of this sock can become restricted over time, by 'sludge' that has built up in the bottom of the fuel tank.
(
'Sludge'. Dirt mixed with moisture that builds up inside a fuel tank. Additives for gasoline that also add to the sludge)

4.Air cleaner element. (Added, because many times this is overlooked by the owner, and can cause bogging down when accelerating hard, if severely dirty. Added as fourth in the list instead of First, but may be the First area to look)

5..Cross-Fire Injection System, (Twin Throttle Body Injection System)
This injection system is controlled by an ECM, (Engine Control Module)
This same ECM also controls the emissions system. (CCC. Close Coupled Catalysts)

It is for this reason, of interaction of the injection, emissions, and ignition systems, that only a qualified, professional technician can diagnose problems with the unit.

Computerized diagnostic equipment, along with the knowledge, and training required, is needed.
