I am currently driving an 86 Z28 carbie 305 with 5 speed gearbox. I also have a 1990 fuel injected V8 with a T700 auto in the shed, it has the computer and all sensors etc but no wiring. What am I up against if I am going to fit this engine into the 86, I would like to keep the 5 speed but is the computer wired to suit the auto? Any help from anyone who has the experience with this sort of engine swap would be greatly appreciated. Cheers, Craig
You can get an "engin swap wiring harness" from jegs or summitt that would require a little extra work on the wiring on the inside of the vehicle, however if you have the original wiring harness for the 90 engine, there is a plug on the inside of the right(pass) fender of the camaro that connects the internal wiring to the external. (plus the fuse block connector under the hood on the firewall on the driver's side) as far as the trans. i did the same thing with mine and kept the 5 sp, the only real problem is that i don't have back up lights.

Those are both fuel injected. The 1992 is a multi-port injection system (one per cylinder), while the 1990 is throttle body injection- one or two injectors inside the throttle body assembly -which looks like a carburetor, but it isn't.
there is a complience plate located on the firewall which has engine #if it starts with 16 its a 1.6ltr if it starts with 18 its a 1.8ltr.also i think that if its a carby its 1.6 if its fuel injected its a 1.8ltr!! hope that helps.
I believe that all cars were required to be fuel injected by the late 1980s in the US. but the only way to be sure is to look at the engine. Is there are big cylindrical dish that looks almost like a tire sitting on the top center part of the engine? if you dont know, try and find the air intake. follow the line past the air filter. When you get to the engine, does it seem to meet with small marker shaped objects, one for each cylinder the engine has? if so, the car is fuel injected. If there is a carbeurator, the dish thing that sits on the top of the engine, the car is not fuel injected
These kinds of troubles should show as a fault on the engine computer. Rent your own scanner and have someone watch it while you try to drive the car. The primary thing you are looking for is whether it is a fuel or ignition problem--sudden stops point to ignition failures as fuel problems usually stumble to a stop. I'm assuming that the engine uses throttle-body fuel injection rather than direct multi-port injection. With throttle body injection, only one injector is involved, and it could cause sudden engine stoppage if the injector solenoid coil opens or loses operating signals when hot. An intermittent crankshaft position sensor or camshaft position sensor can cause these problems. I assume that the engine never exceeds the normal operating temperature. An ignition problem could involve any component of the ignition circuitry including 12 volt supply, but not the spark plugs or plug wiring.
almost every rear drive drive full size used the 305 V8, so u can get an engine from a Buick La sabre, Pontiac bonneville and firebird, also Oldsmobile 88, and don't forget Camaro. any 305 chevy V8 will bolt in, also the 350 V8 will bolt in, this is a much better choice..
CARBY - fuel pump, dies when warms up (most likely if you still have spark)-to test for spark remove a lead and stick a small screwdriver in and sit a few mm from an earth point(dont touch the metal part of the screwdriver) turn the car over you should see spark. - needle and seat - fuel filter (not likely) - coil (if no spark when test)
FUEL INJECTION - i would go straight to the ecu, the 1990 is renound for having a **** ecu, they blow capacitors real easy and carry on in wierd and wonderfull ways. hope i helped.
use 15w-40 for the engine, ATF for the gearbox and 80w-90 for the diffs and transfer box. engine and gearbox have dipsticks for the levels, the diffs and transfer box have removable plugs for level checking, fill until the fluid comes out the level plug.
