Yes,wires will hook up the same and no you dont have to change the chip. I would DISAGREE WITH PART OF THE ABOVE ANSWER. You will need to get the correct computer for this AND NEW CHIP.
NO. Not even close.
The chip is located inside the ECM (engine control module). There is an access cover on the ECM that will expose the chip. A special tool is used to r & r the chip as not to damage the prongs.
You may need to go to a performance shop for a new chip or who knows what. That's the problem with too radical of a modification. Most engine shops will tell you to not go radical on an engine rebuild if it is to be connected back to the same computer and sensors.
You go with a 350 instead.You need the engine with it's computer chip (you can place it into the v6 computer), knock sensor, injectors and TB unit, but since you are getting a complete 350 (and bypassing the 305), you'll have everything you need.Move the v6 mounts up a few inches to the v8 mount holes and bolt back in.Drop engine in place.Done.
Yes your wires will hook up and no you wont have to change the chip either. the wires will hook up but if it is a tbi you do need to change the chip or it will run lean because the timing of the fuel dilivery for the 305 is longer than the 350 and you will run lean so the chip needs to be changed to change the timing of the pulse.
Under the hood above the engine.
You will have to remove the fuel pump from the fuel tank. Then the next problem will be that the transmission that's in it now will not work right because it is computer controled and with your new engine none of the electronics / computer items / sensers will work on the old 350 engine.
You would need to carry over the entire harness including computer from the TBI engine.
to answer this we need to know what size engine and whether diesel or gas engine
It is part of the engine computer.
well apparently a 4.3 litre is a 5.7 with two less cylinders. It's bored out the same as a 350 and so I've beeen told all you need is a 350 engine a new computer and new wiring for the engine and the engine will bolt rright up to your transmission painlessperformance.com and advanceadapters.com has motor mounts for a 350 if you need them hope this helped
Yes it does work. However you will also need to use the 22 lb injectors for the 350. To get the full benefits from the upgrade you should get a 350 chip burned. The computers are the same but the chips are different. This is all considering if the swap is for a lb9 (305) to a l98 (350).
yes. it should work fine.
Usualy the torque difference fom the 305 to the 350 will cause a hard shift problem but check with the aftermarket computer chip co. but yes this can be swapped over. also be sure to switch all of the sensors etc so the change over is identical...
Depends on the specific engine, need to know what vehicle and year.
YES, if you know what you are doing. You will need the complete engine and transmission wiring harness and computer plus the fuel pump for the 5.3L engine. The wiring harness and computer on the 97 will NOT work.
Yes but it has to be a vortec 350 so evrey thang matches up to the computer.
You could look for Hypertech products, which are distributed by Autozone, Advance, and O'Reilly's.
yes you can, you will need new motor mounts and have to go with a HEI distriburetor so you can eliminate the computer.
PROBABLY a faulty knock sensor, however, you'll need to run a computer diagnostic test to find out for certain.
Yes but the transmission will blow you need a racing 350 transmission
As long as the 350 is a fuel injected engine / TBI / Throttle Body Injection engine there is NO difference.
Need to know the year of engine and what it is in. YOU WILL NEED TO ASK YOUR QUESTION AGAIN with that info. THANK YOU.
