If you are changing your 305 for a 350 on your 1993 K1500 with an automatic transmission will the wiring hook up and do you have to replace the computer chip?
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.
Where is the computer chip located on a 1991 Chevy Suburban with a 350 V-8 TBI Auto 4 wheel drive?
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.
On a 1998 4x4 Silverado with a 350 Vortec bored to a 383 stroker how do you get the onboard computer set for the modified engine to turn the service engine soon light off?
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.
Will a computer chip out of a 89 Chevy with a 350 work in a 2000 with a 4.8?
NO. Not even close.
4.3 L V6 engine in your 1990 Cheyenne was there a 305 V8 for that year and if so would you have to change the motor mounts or do any other mods if you install the V8 instead?
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.
If you change your 305 to a 350 in your K1500 with an automatic transmission will the wiring hook up exactly and will you have to change the computer chip?
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.
How do you make an engine harness to install a 1986-94 350 TBI Chevy engine in an older carbureted vehicle?
You would need to carry over the entire harness including computer from the TBI engine.
What do you need to do to put 350 4 bolt main carbeurated in your 94 z28?
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.
How do you swap a 4.3 liter motor with a 5.7 liter motor?
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
How do you change from a 305 engine to a 350 in a 1985 Monte Carlo ss keeping the computer and transmission?
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...
Can a TPI set up and computer from a 305 TPI be used with a 350 block and heads?
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).
Where is the engine computer in a 1992 1 ton 350 dodge van?
Under the hood above the engine.
