Tim240z Posted January 7, 2005 Share Posted January 7, 2005 Anyone know if any of these motors from the 2000+ chevy trucks and vans have regular cable throttles, instead of drive by wire throttles. (looking to retrofit my 71 Cheyenne 20. I would like either of the 2 above, or an LS1 with overdrive auto. Any reason why the LS1 would not be a viable option in a 3/4 ton truck? Thanks, Tim Quote Link to comment Share on other sites More sharing options...
mark Posted January 7, 2005 Share Posted January 7, 2005 I've had a 2000 suburban and a 2000 Z 71 pick up. Both with 5.3. One had cable and one had throttle by wire. The throttle body looked the same except the suburban had the throttle control motor bolted on the side. Looked like it could be removed and replaced with the cable setup. Hope that helps.

Tim240z Posted January 7, 2005 Author Share Posted January 7, 2005 Thanks Mark. Do you know if the sensor on the pedal was wired directly to the TB, or if it was an input to the PCM? Quote Link to comment Share on other sites More sharing options...
mas28O Posted January 7, 2005 Share Posted January 7, 2005 Tim the early 5.3 have a cable and the later years switched to drive by wire throttles. You can buy any 5.3 and then just put on a cable TB. 5.3 motors are cheap on ebay now. Mike Quote Link to comment Share on other sites More sharing options...
Tim240z Posted January 7, 2005 Author Share Posted January 7, 2005 Mike, Does the same apply to the 6.0 and 8.1? I don't want to downgrade the driveline to a 5.3L. I sometimes haul heavy stuff and will be building a car trailer (double axle) as soon as the weather clears, so I need some punch.
