it should crank back up in the donor vehicle with the fuse pulled and the bmc wires disconnected without having to do the 30 minute relearn. or it'll crank your motor up in your truck. on the wiring there are 2 wires you can hook up, and have a stand alone harness. just keep the fuse block out of the donor. bypass vats first though of course.just saved you some more money on a harness:party36::cheers:
no sense in paying someone else to do it if you have access to EVERYTHING:Nonono::shakehead::buttkick:

if you have any questions feel free to PM me.

You will need to change out the Frame mounts. The V6 ones are different than the V8 mounts.

Let me look for a pic....i found these on Ebay for $100.

You must be registered for see images attach

They bolt to the frame and then your engine (motor mounts) bolts to them.

Isnt that what these mounts i boyght are for? I thought the 4.8 mounts stayed where they were on the engine then these went from the mounts to the frame?

The mounts you bought bolt to the frame stands. The V6 and V8 frame stands are different, so you will need V8 frame stands to bolt up the dirty dingo mounts.

pics of the 87 chevy r10 SWB with 4.3 tbi , the 350 4bolt main i had planned to convert to tbi but lost interest, my 2000 chevy silverado 1500 4.8 vortec i have for a donor truck(74k miles), the interior of the 87- leather buckets seats that were in the garage.. not sure what they came out of.. the motor mounts for the 79 350, which are a 3 bolt design which looks very close to those on the 4.3


sorry about the pics being sideways... not sure why, when i open them on my computer they are straight

They may work, it's worth a shot. I think they may be bolted to a different location on the crossmember though.

in the mean time I'm still looking for a set of frame mounts... having a hard time locating any online for sale.. don't see anything on eBay, hoping i can find a set local before my parts arrive but these trucks are getting scarce now.

It took me a while to find them. Try Car-part.com also.
