H3T engine issue

[H3-ALPHA]

Hello fellows.

I recently bought an H3T, with a blown engine. It is very rare to find H3T in here. I have owned earlier H3 I5 and H3 alpha which I regret selling. The H3T is in great shape but is not working due to an oil pump failure which caused internal damage to the I5 engine.

I have 2 options:
rebuild the I5 engine from scratch.
do a 5.3L swap.

I am looking for a complete 5.3L engine and harness plus the fuse box plus the ecu. Do you know where I can find them? What about doing a 5.7L swap? 5.7 engines are available around, as well the 6.0. But I guess it would be a hard swap not having the plug n play harness for the truck.

I need your help guys.
cheers.

A 5.3 LH9 from the H3 and H3T 2010’s would be straightforward swap since that is the motor offered by GM. There are some folks here that have done the 6.2 swap but I don’t know which engine.

You’ve had both the I5 and the V8, is it even a question of rebuild vs swap [emoji6]


And the price difference between the two on AutoTrader and eBay right now is huge.

I’ve also seen the LH9 on eBay for ~$1000 recently so I am sure you can get some good deals…

Hmm, waiting for others to chime in. But the 6.0 is the same LS family as the 5.3, which is a reasonable swap. I don't know that the 5.7 would be as easy to source the additional parts, or to follow already practiced engine swaps. Many have done 5.3s, 6.0s and 6.2s.


I5 rebuilds are not as common, or at least not boring out and turning into a stroker or other larger displacement engines.

true.
my only concern is the harness to make sure everthing will be working as it is. Do you know by chance anyone selling the H3 harness alpha edition?

A straight forward rebuild will most likely be most efficient and cost controlled. It already has the engine so lol just get wrench'n.
