Official NBS 4.3v6 to GEN 3 V8 swap Guide

[zebra]

Well first off, congrats on getting it going

thanks

By your year i'm assuming you have a throttle cable style intake and not fly by wire. I am not sure but it may be your throttle positioning sensor or motor. These two items are located on the drivers side of the throttle body and could contribute to your wierd idle because in the winter when its cold my v6 does the same thing and my mechanic told me it was one of these culprits. As far as your guages and tach not working i don't have a guess on that one...

yep - cable throttle (DBW started in 03). tomorrow, i plan on getting some MAF cleaner & spraying the IAC down & also resetting the TPS (i was told to disconnect the negative battery for 10min while i remove & reinstall the sensor)

as for the cold... well, it ain't really. even if it was, i would understand it idling high (around 1500-ish) for a minute, but living around 500 or less is wrong

I got my harness all squared away. A the owner from KNOX Auto Supply was a real help and was able to next day air ship me one from TN so i could still do my swap this weekend. Hey also when doing this v8 swap can you use the stock v6 torque converter???

Knox Auto was a let-down for me. the shop owner where i did my swap gets stuff from them all the time & i bought an 02 L59 from them but when it got here, the harness was cut & some of the accessories i bought were missing
the replacement 02 LM7 they sent looked like crap (from sitting on the warehouse shelf for 3 years [keep in mind, i specifically said to not send an engine that'd been sitting more than a couple months]) and was missing an exhaust manifold. we just ended up doing a complete return/refund.

a month later, i finally found a fresh (in the yard a month, still in the truck) 01 LM7 in tompkinsville, ky

as for the V6 converter - i believe you can use it, but i'm a standard guy so what do i know?!
