My swap. 5.3 LM7 into 1990 3/4 ton 4x4 suburban.

Figured i should share my swap with the folks on here. Here's what i got. 90 burb that originally had a tbi 350 in it. Has a th400 trans and np241. Anyway, trying to do a factory looking job without being obsessive about it.

On to the pics!

Motor mounts from car shop inc.



Flex plate spacer.



When i picked up the motor.



My Blazer when i was picking up the motor.



Unloaded the motor and started cleaning and prepping it for the swap.



Pulled the intake and started cleaning and prepping it.



Pulled one of the valve covers. Looks pretty good!



Pulled the hood off the burb and started taking it apart.



Ready to pull.



Out.



Waiting for someone to buy it. Currently on CL.



Now cleaning the engine bay before i drop the motor in. Should be putting it in Monday. This is the "before" cleaning shot of the engine bay.



And thats where im at so far. I got the computer and harness already done with the motor. Got the autometer oil pressure sensor adapter, VDO water temp sender, ep381 fuel pump, and fuel line adapters. Just have a few more things to pick up like a fan, throttle cable, radiator hoses, alternator, and o2 sensors. Should have it up and running in a few weeks.

Good amount of progress. Hopefully it is up and running soon. Also nice Blazer, what year is it?

[myzterray]

nice start! any mods? cam? headers?

Save the ac compressor if it was working. They make a kit to use it on the new engine.

Thanks! The Blazer is a 79. No mods to the motor at this time. The swap is about the limit to my available funds... The A/C was good but was completely empty so it was leaking from somewhere. I think im going to leave it off for now and later do the sandan compressor mounted high with the relocation brackets.

Thanks! But right now im pretty well tapped out financially just getting the thing on the road.

Got my fuel pump and temp sending unit today!

Got the new motor dropped in today! Also set the intake on to see how it will look.

WIRING! Actually its going pretty good so far. I got rid of the tbi harness tonight. THere is still a few wires left over that go to the driver side that i have to figure out that i will probably be asking about here soon. Also mocked up the exhaust manifolds. The strange thing is that the passenger side clears super good but i might have trouble with the driver side! Anyway, you know me, on to the pics!











Left over wires.



Removed wires.



This goes to one of the injectors on the TBI setup. Wonder if this could be part of my problem? Screw it.

That looks real good to me. Which engine mounts did you use?
