1996 318 to 360 swap need help
 

Hello everyone...I hope I can give enough info for someone to be able to help. My friends 318 in his 1996 1500 locked up. So he bought a used 1996 1500 with a 360 in it and a bad transmission. Both are 2wd one bad engine one bad transmission. So here we start. We swapped over the 360 engine into the truck that had the 318.Everything went well and we even got the 360 to turn over and start but it will not stay running at idle we have to keep feathering the throttle to keep the engine running. The only change that was made was to the intake due to a sensor on the front of the 360 had 2 sensors and would not match up with the wiring harness on the truck that had a 318. The 318 intake only had one sensor position this sensor was located one the front of the intake. The intakes lined up perfectly as far as size and bolt pattern. We used the fuel rails and injectors off of the 360 and put them into the 318 intake.

Question #1 We did not change out the computer or wiring harness does the 360 have to use the original computer and harness from the old truck to run properly?

Question #2 Will the 360 block work with the 318 intake, and 360 fuel rails?

Question #3 We tried to adjust the timing by turning the distributor cap but could not get rid of any of the problems. Do we have to disconnect the computer from the sytem in order to tune it with a timing light and the distributor cap.

I hope I have explained the situation and the circumstances well enough to start a topic any and all help from someone who knows more than we do will be greatly appreciated.

Oh and 1 more thing we replaced the balanced fly wheel off of the 360 and put in the 318 so it would not be out of balance or a a harmonics or vibration problems so we used the 318 sensor on this part as well.

Summary

Block 360
intake 318
fuel rail and injectors 360
computer 318
wiring harness 318
flywheel 318

You need the 360 computer installed as well.
