1987 Suburban 350,700r4 & np208 swap in 1984 K10

[Preston]

okay, I have found (1 1/2 hour away) the motor trans and transfer case out of an 87 suburban to install this engine in my 84 will I need any additional electrical gizmos to make this swap work? Thanks for your help

Do you want tbi, or will be converting to carb? If carb, then just need to add control for torque converter lockup. If tbi, then harness and ecu and fuel

 

[Preston]

I’m not sure which way to go but looks like tbi would not be too difficult to set up, thanks for your help

If harness complete and have ecu, essentially just putting it all together. Would need to add a fuel tank with fuel pump and fuel injection rated connections/hoses.

 

[Preston]

Don’t believe I have the ecu, just the harness to the fuse block

I’m not sure this is a 700r transmission can you help me this was removed from a 1987 Suburban maybe a 3/4 ton the pan looks too small to me might need to take some more pictures thanks

Not a 700r4. Maybe th350 or th400.
Should be th400 if from a 3/4 suburban

Passenger side of the pan rail looks to be a th350. 700r4's were available in the 3/4 ton pick-ups in '87 along with the th400. Don't know if they made availability of those different for the 'burbs or not, but I guess it's a moot point anyhow as this looks to be a th350.

I’ll get a better picture tomorrow but there is a modulator valve on the passenger side it’s hiding in the picture, thanks I have to figure how to get it out of the trailer, maybe find a tractor, backhoe or a low limb close, I have a engine lift but not sure it will pick all this up at once.
