Default H3 LS Swap

Hello everyone
I recently purchased a 2007 H3 with a blown up engine. instead of overhauling to 3.7 5 Cylinder engine. Was thinking of swapping with a 5.3 LS Engine.
im sure its been done before. any advice on how to or what is needed, Compatibility issues ect would be greatly appreciated. thanks in advance

Welcome to HF.

As far as the swap.
SEARCH, Search, search... info all over the WWW on H3 I5 to V8 swaps.
READ, Read, read... very few complete A-Z build threads on H3 I5 to V8 swaps.
SAVE, Save, save... expect to pay more than what you originally budgeted for an LS swap, A LOT MORE.

or you could just buy an 08-10 H3 Alpha for less than the cost of your current rig and a swap.

The swap is not a direct bolt in, takes a bunch more than that.

Put an I5 back in it, get in running right, sell it and buy and Alpha = done.
